Bulldozer Final Thoughts

Those of us hoping that AMD's Bulldozer CPUs would catapult ahead of Sandy Bridge performance must live with the disappointment. Considered on its own, the AMD FX-8150 CPU is a great processor with excellent performance (especially if you can keep all eight cores busy), and in many cases beats the Intel Core i5 2500K. But there are few real-world applications that gamers and enthusiasts use that will fully exploit it; in fact, as you can see from many of these benchmarks, even programs designed to spawn multiple threads frequently do not scale their performance well past four cores.

Of course, having eight cores also means you can have a lot of background stuff going on and still keep things perky in the foreground application, and AMD has some persuasive demo videos showing how much smoother multitasking is with real cores as opposed to virtual cores, but it's a hard thing to quantify.

The 32nm fabrication process and other architecture improvements give the FX-8150 good overclocking headroom, and AMD's aggressive turbo frequencies represent the first officially-supported 4GHz and higher clock speed in any consumer CPU. But the Core i5 2500K has lots of overclocking headroom, too. Since overclocking results aren't guaranteed, the comparison chart below is based on each CPU's scores at stock clock speeds.

Using these benchmarks, the stock-clocked AMD FX-8150 averages 2.2% slower than the stock-clocked Intel Core i5 2500K. But as you can see looking at this chart, the individual differences are typically much higher: the FX-8150 tends to win big or lose big. It would be easy to choose a mix of benchmarks that gave a decisive win to either CPU, but I tried to use as broad an array of tests as I could to give the most accurate performance comparison.

As I showed in the single-core section, the performance of a Bulldozer core is not significantly better than the performance of the older AMD Thuban core, and both are far behind a Sandy Bridge core, so AMD's banking on keeping all eight cores filled to get the best performance. And indeed the FX-8150 can return excellent performance in these cases, although the performance improvement is less than what you might expect given the extra cores. And if software vendors upgrade their products to use the new instructions AMD has integrated into Bulldozer, its performance will improve more.

AMD claims the Windows 7 thread scheduler doesn't make the best use of Bulldozer's architecture, and says that we can expect a 10-15% performance improvement when Windows 8 ships. Also, Bulldozer is just the first in a line of new processors: in the coming years we'll see Piledriver (2012), Steamroller (2013) and Excavator (2014), each of which AMD says will bring improvements in performance-per-watt and instructions-per-clock.

But Intel's not standing still. Before the end of the year we should see Sandy Bridge "E" processors, and next year we'll see the 22nm Ivy Bridge processors, which according to rumor will drop right into existing Cougar Point motherboards, enabling Intel users to easily upgrade their systems. AMD FX CPUs are only officially supported on AMD 9-series chipsets, although several vendors have said that their 8-series motherboards will support FX processors with a BIOS upgrade. When specifcally asked about this, AMD said only that official support is limited to the 9-series chipsets, but that individual vendors were free to do what they wanted. We'll see, I suppose.

Given the market for this processor, you might wonder why I didn't include game benchmarks. The reason is simple: at high resolutions (say 1080p and above) and with multi-monitor systems, the critical factor is your video card setup, not the processor. Assuming the same video card configuration, your Bulldozer gaming rig will not give you a noticeably different experience than your Sandy Bridge gaming rig. If you're an AMD fanboy like me, rest assured that a Bulldozer system is an excellent base on which to build a high end gaming rig.

A few weeks ago I attended an all-day press briefing on the Bulldozer architecture at AMD's Austin, Texas headquarters. One of the points AMD made was that performance is only one aspect of a processor; another is performance per watt. But while AMD's server processors and E- and A-series APUs excel in this area, the FX-8150's 125 watt TDP is 32% greater than the Core i5 2500K's 95 watts. Granted, most desktop system users don't consider processor power draw when designing a system, but there it is.

AMD's weakness remains its integer core (APU) performance, which Bulldozer does not significantly improve over Thuban. More cores can compensate for this in some circumstances, but overall in my tests the FX-8150 can be considered at best to have achieved performance parity with Intel's 2500K...at a $254 MSRP as compared to the 2500K's $216 MSRP.

This was suppose to be AMD's next step up.. It looks like they missed the step and fell all the way down the landing.. It is a good chip, No Doubt.. But it is not the Great Chip that we expected.. The 8130 was a bust before it started.. thanks for not releasing that one. But the 8150 was the next step up and well.. Like most AMD chips of today.. I guess its okay. but it makes me wish now I would have bet on INtel instead of The Bulldozer.. Sorry. Guys.. I am usually not this down on things but it is really disappointing that it didn't kick the Llama's Axx.

Thanks for the grandiose statement about how this affects you. Please note that the team at AMD is not all about realizing YOUR expectations.

BTW, why would you bet on a chip?

Every time someone releases a product there are people like you who dump all over it as if you've been personally harmed. Please get some perspective.

It looks like the benchmark test did the dumping here. His opinion is every bit as important as yours is, and I don't blame him for being disappointed (as I am as well). I was also betting on (rooting for) AMD, but it looks like the win is just not in their column this time.

The perspective that needs to be gained here is that he has as much right to his opinion as you do to yours without being labeled as "dumping all over it". You work for AMD or something?

If you bought an AM3+ motherboard then you bet on the bulldozer. Granted you can still use a phenom chip on the motherboard but the main reason people bought the AM3+ was for the future bulldozer chip. It is disapointing that the fx 8150 did not do as well.

I am also disappointed big time. I have been using a core 2 quad for a couple of years and was planning on upgrading this winter. I was hoping for the Bulldozer (I always root for the underdog), but it looks like I'll be going Sandy Bridge.

I totally agree. I just ran benchmarks on this chip after spending about 1200 on the best possible setup to configure this on, and it was barely faster than my 1100t. Very disapointed. After years of repping for the underdog, I think I'm calling it quits. Time to sell this setup and build a 990 extreme.

so far i've been really impressed with the chip battlefield 3 in % cpu usage barely tickles the 8120 you could run the game twice and still have enough left over for antivirus defrag or god knows what else. And yes i am a little disappointed with its gaming bench tests i read in PC Format. But still its doing me really really well.

Which is why you shouldn't pay too much attention to benchmark results, unless you're doing stuff like video transcoding all day long.

My "Intel system" is an overclocked Core i7-3960X CPU and two GTX580 video cards in SLI. My "AMD system" is an overclocked FX-8150 and a single Radeon 6950 video card.

With a 27", 1920x1200 monitor, I can't see any difference in any of the games I play between one system and the other. Sure, I can measure frame rate differences with benchmarks, but these aren't noticeable in actual game play.

The situation would likely be different were I running, say, a triple-monitor setup. But how many people actually do?

I think I may have the answer to this, I also have an awesome 8150, which really is the best value processor you really could want right now...

I have noticed that when I run the Windows test, it only loads all cores to 60%! Try it yourself download the CPU gadget for your desktop...

All CPU Meter from addgadget.com is a good one, and you will see when you run the windows test it only loads the AMD to 60%!!! What about the other 40%????

This is why its showing a low score... Trust me this CPU is one of the best multitasking cpu's on the market right now...

You don't get the other 40%; the other commenter is simply noting that Windows' built-in "Experience Index" is a crappy indicator of overall system performance. Well, at best only a very rough indicator. In other words the test is written in such a way that it doesn't use all the performance of which your CPU is capable.

I have to agree with you, I feel that some of the reviews for this processor have been very biased indeed, us AMD boys & girls know that, AMD processors are built for multitasking first and GHz second. I have been blown away by my build tonight, and I am so looking forward to adding my solid stare hard drive to finish it off. It really does Rock, also someone on here said it scored 7.2 in the Windows 7 performance test, in fact on my system, with no over clocking I have a score of 7.7...

Also its my first build with all AMD, AMD chipset, processor and the new AMD performance memory 16gb's worth, all in all only cost me £350 for the mainboard, memory and processor and £100 for the ATI 6850 gcard and another £150 for the 256GB solid state hard drive...

If this was an I7 build it would have cost near £1000 and its not even a real 8 core processor...

What else can I add it really does rock. ;)

Multitasking with an AMD system is way better then Intel, I have seen both working side by side, hit 8 or 9 items on intel and watch the judder, AMD does not do that, remember they was the first CPU company to do away with the bottle neck bus system Intel use, Intel learnt a hell of a lot to get where they are today, most of it from AMD...

Actually not: a decent 9x0 Mobo ($100) and a fx-8150 ($205) cost more than a 2500k ($185)+decent z77 Mobo ($110).
And you need a $100 H100 or a custom loop to reach 4.6GHz with the fx, when a 2500k does it with a $30 Hyper 212.

I can't even sell my fx-8120: it's such a failure than nobody wants one! Even at 120 bucks!

why does every one bust on products when there first benchmarks come out. bulldozer is a brand new design. non of the software is designed to tap in to its potential and its brand new. give it a month or two after the release of windows 8 and bulldozer should see a 10-15% increase in performance. plus there is the fact that the 26ook has been out for half a year. its had a much longer time to fix issues and bugs then the few week old bulldozer.

# RE: RE: RE: System AdministratorDavid Ramsey 2011-12-14 16:27
Well, that's what AMD says should happen, and some web sites that have tested with the developer Win 8 have seen some upticks in benchmark scores. Since each Bulldozer "module" shares cache and instruction decoding resources, it's faster to run two threads on two separate modules rather than two threads on the same module. Windows 8's scheduler will be "Zambezi aware" and try to schedule threads on the least-used module.

It remains to be seen if this strategy will have any real-world impact, but benchmarks will certainly improve if they're multi-threaded.

# RE: RE: RE: RE: System AdministratorOlin Coles 2011-12-14 16:35
Of course that's what AMD says, it only makes sense to claim performance in an Operating System that doesn't yet exist to the public. Windows 8 is still at least 1-2 years away from release, and by the time it's public you can bet that Intel will have surpassed Bulldozer by a longshot.

# RE: RE: RE: RE: System Administratorkiv 2011-12-14 17:32
I thought it was the opposite. That Windows 8 would try to load the modules up, which would then free up other modules to be deactivated and allow for optimal Turbo Core clocking. My understanding is that with the current scheduler, all of the modules remain active, and Turbo mode doesn't end up being used at all.

I hope they pull a rabbit with Piledriver. The decision to focus on clockspeed rather than shortening the pipeline seemed like a strange plan.

Your comments of 'bias' make me laugh - especially when you clearly don't know what 'faster' means or have any concept of how many Phenom II processors exist at varying speeds. We test the product, publish the results, and that's that. Then we give people like you access to them, for free. Still, you ignorantly believe we're going to report negative results that don't exist for a product supplied to us knowing we must maintain a long-term relationship with the sponsor. Quite silly, when you think about.

Your build was not upto the task, please tell me you sourced your own mainboard rather than using the stock one sent. I never use stock, I pick and choose the best, which can give the processor an edge, never been a fan of MSI, they seem a bit slow for some reason, love ASUS and my new system is built on an ASUS board using AMD performance memory, its the first build, I have had where all the processing power, GPU and chipset have all been sourced from 1 company... It can make a big difference!

I was trying to find the chap who quoted that his Windows 7 performance score at stock was 7.2, I do not believe in overclocking, why damage a system to get another 10% out of it. My system at stock scores 7.7 with the same for memory. So build quality can make such a difference even you should know that.

And dont take it to heart, I did not mean to offend, just could not understand why your scores were lower!

We always test with the latest BIOSes available at the time of testing. If you check the results you'll see that both the ASUS and MSI motherboard are turning in virtually identical scores at stocks speeds, so I feel pretty confident about the results.

Obviously the Bulldozer CPUs were brand new at the time of these tests, and vendors have have more than six months since then to fine-tune their BIOS code. I imagine if I retested today with the current BIOSes the scores would be somewhat higher.

Now thats an idea... What with software updates and firmware updates... Could you run a retest now? have you still got the rig or do you have to send them back?

As I said somewhere else, someone said they got 7.2 on the WIn 7 check, but I am getting 7.7 at stock speeds... Might be worth a follow up, how about running it with Windows 8 so we can see what a difference we may get, as AMD say it does run better with WIN 8, however saying that I am very happy with the way my system is running, its a very nice processor which I feel will be more future proof then others. ;)

Ok how about just 1 test, which you ran before?

Have you checked to see if any updates are out for your mainboards. My bios for mine was completed end of FEB. How much performance can you get from just software and BIOS updates?

Have you ever tried it before, say with the Sandy bridge when they were slowing down...

The optimizations AMD is talking about work like this: since each Bulldozer module has shared resources, if there's only one core running in a module, it can use _all_ the cache and other resources. So if you have two threads, it's faster to run each thread on a separate module rather than run both threads on the same module, since then you'd have two cores each with the full module resources available rather than two cores sharing the resources of one module.

You are right in some ways. The ribbon looks like it's there to stay. Never liked it, never will. Even in Office you can't get rid of it, only hide it until you need a menu function. I suppose there could be third party apps that will help out making the start menu a little better (I like the search in the W7 start menu, and the functionality of the XP start menu). They likely have not addressed the problems with the W7 windows all opening on top of each other and not remembering their last size (I'm running 3rd party apps to correct that). Even with those minor little problems I still liked W7. I'll hold off on W8 until I'm satisfied I can change it to what I like. Metro may be great for a tablet (even if it won't run Windows software) but personally I'm not interested in any of that UI on a desktop. I'm all for "under the hood" upgrades, but it seems to me like they are ruining the GUI even though they say you can default to a "more traditional desktop", but it turns out to be traditional in appearance only. Of course everything could be fixed by adding a magical "Use Traditional Desktop" check box that actually defaulted to a real XP/7-ish GUI, but for some reason it seems that it is beyond Microsoft's programmers skills.

Not be nitpicky, but... Okay, it's entirely nitpicky, but nevertheless:

The 1090T is $20 dollars cheaper than the 1100T (at Newegg), and only .1GHz slower, but it's still a Black Edition, and I'd venture that the overclocking is not that much better, if at all better, between the two. On top of this, the older releases of Phenom IIs are regularly seeing $10-$15 promo-code sales at Newegg, dropping their prices even further. $114.99 dollars for Phenom II x4 965 or (for a current example) $159.99 for 1090T is much more justifiable than spending $190 on an 1100T when ~$20-30 extra will get you a 2500K.

You told them you were overclocking? If your CPU dies, you just send it in. Put a note with it that says "it just died". What more do they need?

However, I have to point out that if you are overclocking (as I am) it's up to YOU to take responsibility for what you're doing. Most of the time you can get away with it, but if you kill a piece of equipment while overclocking, there's no one to blame but yourself. That's the chance you take when you overclock. This is hardly Intel's fault. I know people these days don't want to accept responsibility for anything, but in this case no one else is responsible.

Your post doesn't make much sense. First of all, all overclocking always voids warranties. Most manufacturer's will replace things if you open the case as a failure, and not tell them you fried the chip with overvoltage. Secondly, memory speed can't do damage. The only way memory can do damage is excessive voltage on the memory frying out the IMC on the CPU, which is something you need to be careful about. Sounds like you don't know enough about overclocking to be doing it. And I'm not trying to leap to Intel's defense here, I'm using a Phenom II at the moment.

I had the first AMD with 3DNOW, waited for games to support it, then my chip was old. I had the first 64bit processor, XP 64bit was a flop and had to wait for Vista 64, then my chip was old.

The only time this ever worked for me was with the i7 920. My longest running chip between upgrades, still have it three years later, blazing at 4.2Ghz with apps that can use it's cores.

This has to be "The" benchmark of all benchmarks on the Bulldozer. Damn, my head hurts. Good, no, great job.

As a comparison, I ran the Cinebench 11.5 benchmark on my rig.
Core i7 920 3.8OC
OCZ Gold 12GB RAM at 1440Mhz
MB: Gigabyte x58 Extreme ver 2

Cinebench 11.5 score: 6.27

I ran it with many open programs taking up over 4.5GB of ram. Some of the apps I had open were Photoshop CS5, Lightroom 3, ZoneAlarm, Avast--which I shut off for the test, but left the program loaded--Open Hardware Monitor, several utility gadgets, Speedfan, Foobar 2K, Firefox 6, and several more background apps. I don't know if that would make any difference, but I just wanted to list them in case. (I couldn't close out all my apps because I had open work in them. I didn't reboot or anything. I just downloaded it and ran it.)

Well, it looks like we'll have to wait once again for the prize fight between AMD and Intel. Not a bad fight from AMD, but once again, falls short of the prize. Since 2004 and x64 AMD has gotten its ass kicked by Intel every time, except in the price range. Ouch!

I built my Intel system back in January of 2011 (This year). I am not sure what AMD is thinking or doing but they really need to get out of the fish bowl and start creating some technology that comes close to their competitor. I used to be nothing but an AMD fan until the release of the Core 2 DUO series came out. AMD started getting an ass whoop about that time. AMD has a good mid-level price for all types of PC's but I think their fans want a crown. My 2500k rocks out at 4.1GHz all day and it is a beast.

In the price battle between a 2500k setup and an FX-8150, I think AMD has a clear win. I'll also say that time spent doing something like converting between video formats in handbrake is more meaningful to me than integer vs. floating point...to be honest, once I'm at the performance level of either the 8150 or the 2500k, then there are very few benchmarks other than that which would give me pause or produce noticeable differences in my experience...would anyone else care to comment on specific tasks where you could immediately discern the differences?

# 990FX makes 6G RAID very easyMRFS 2011-10-12 10:18
One of the things I've noticed about current Intel chipsets, as implemented by Tier 1 motherboard vendors, is the SPLIT that occurs with the integrated 6G SATA ports: often, the Intel chipset supports maybe 2 or 4 native 6G ports, and 2 or 4 more 6G ports are handled by third-party controllers. This imposes less flexibility whenever a designer wants to have fast storage -AND- save money by doing so withOUT add-on RAID controllers. If one wants a RAID with 4 members + other storage devices, all controlled by the chipset, the 990FX appears to be a better choice. Of course, this should change when Intel's X79 arrives, but that chipset is also expected to come with a price premium -- not the least of which is the cost of a new LGA2011 Intel CPU.

Ideally this would be an investigation of varying-quality CPUs combined with top-end equipment in the other categories of system construction for the purpose of figuring out just how much you could skimp on the CPU before it starts to noticeably hamper the gaming experience. This would be the sort of article to put an end to the marketing-driven idea that you must have an i7-2600k or FX-8150 to experience good performance, and more importantly to educate as to what level of CPU would actually be sufficient.

Exmples of questions I am curious about: would a Single-Core AMD processor running at 2GHz be sufficient?
Would a Dual-Core Athlon processor? Would a Dual-Core Sandy Bridge? Do these lower cost parts degrade the effectiveness of high end GPUs like the GTX 580 or AMD 6970 such that those high-end GPUs practically require high-end CPUs to match?
etc, etc...

I think I'd choose a quad-core processor because, as seen in the referenced article, there are situations in which it makes a significant difference. With an AMD Phenom II 965 Black Edition going for a mere $130, it's a cheap way to ensure the best performance from multiple-card systems, or systems running at high resolutions.

Farnsworth Worthington: Just speaking from experience and I should be ashamed for not posting my experiences and builds online. If you are looking for a budget build PC and want some head room for gaming then you have a few choices from both AMD & Intel that will not break the bank. The majority of budget gaming rigs built all use an AMD processor. Recently I built a budget system right in the $500 range with more than adequate performance parts using a AMD Phenom II X4 945 Deneb 3.0GH Processor, an ASUS M5A87 AM3+ AMD 870 Motherboard, 8gig of G-Skill Memory, 500gig WD Blue Hard Drive, 585watt PSU, EVGA 550Ti GPU. I have not ran any benchmark tests yet as time is very constraining lately with getting machines out there. But I will say this, Battlefield Bad Company 2 plays on high settings at 1920x1080 & 1920x1200. Battlefield 3 Beta Played the same. Both games yielded 40+ FPS in Online Gameplay and that is enough for a great gaming experience. Again there are many other builds a person can configure this is just the one I found that is easy on the pocket and provides some good performance while giving the end user a Quad Core PC that is better than what the average gamer is using. If your budget is $500 I stick to AMD products, if your Budget is $750+ I stick to Intel. You do get more performance with Intel over AMD on top tier procs but then you also pay out the arse for it (as everyone should know by now). Do you need the 980x Intel Processor? Or do you want it? If your rich then reach for the stars and I would gladly help you get there :)

But what is the "minimum" FPS. That's the most important measurement, since low FPS can cause stuttering and really ruin the gaming experience. What I mean is that if you can run 40FPS average, but every time you get fired on or a blast goes off your FPS drop to 15, that's not going to work.

Doug Dallam: My apologies. When I list a FPS I always list the lowest, never the average, for the same reason you stated. And to be honest the lowest score on Battlefield 3 (Beta) was 41fps and in Bad Company 2 44fps. And for those of you who didn't know, Battlefield Bad Company 2 is very processor intensive so it is a good test game. If I remember corectly the averages were in the mid 50's for both games and reached highs of 70+ but that was in empty servers only. My point I guess is that if you have a system hitting a low 40fps, your getting some pretty good entertainment online :)

If you want to know how little processor you need to run games, choose your video card and then contact the car manufacturer and ask them what level CPU you need to take full advantage of the card. There is a point where you won't get anymore FPS from a card due to CPU limitations. For instance, I had a AMD X64 4800 and I got no increase in FPS going from an nVidia 7800GTx to an nVidia GTX260. the CPU was the limiting factor.

Well, if you want to know if you are cpu limited, that's quite easy:
Downclock your gfx card with the driver utility (CCC for ATI° to half it's frequency and run 3dmark11. Check graphic score.
Increase the gfx card freq by 10%, run 3dmark11 and check gfx score.
Do so until you reach either a constant gfx score in 3dmark11 (cpu limited) or you max card clock (not cpu limited).

If one looks at Cray's use of the Opterons in the supercomputers that it builds, one would have to say that AMD tech has some advantages. Also, lookiing at the instruction set tests that were done, it is fairly obvious to me that it is the tests that are lacking rather than the processor. In W8, I suspect that the 8150 will outperform the 2500k in most aspects. There iks clearly also something wrong with the memory bandwidth tests, which I suspect has to do with the cache fill rate design of the tests. If I were putting money into a medium priced system now that would stand up for a longer period of time, I would probably go with the 8150. Also, the additional PCI-e lines will go a long ways towards future-proofing the system for various types of high speed IO like USB3. Since Intel always has a big lead in instruction optimization in compilers, most tests, unless they are hand coded, will not reach parity on the AMD instruction sets for a year or more. Even then, there are a lot of companies that will not make use of those optimizations, preferring to get brownie points with Intel by so doing...or they are just lazy. Yes, that means that in the real world, Intel will continue to dominate,m but that does not mean that the domination is due to superior technology.

Here's a thought. Since AMD whipped the Intel's ass back in 2004, but since has been getting its lama whipped, consider that with each passing year AMD has offered CPUs that are--wait for it--slowly catching up to the penultimate performance of Intel. They've already shown they can out perform Intel in price to power ratios. If I were Intel, I'd be concerned, not scared, but definitely taking AMD as a serious competitor. And, I'm sure Intel does just that.

Think about it this way too. Bulldozer is AMDs first real change, on par with Sandy Bridge, in a while, and they are already near top performance of Intel. Now, I said near, not there. But Bulldozer is the first iteration of a whole new approach to CPU development by AMD that current OS's don't support or don't support well. (The same thing happened with SSDs and Windows, if you remember.)

How well will Bulldozer technology scale compared to Intel's? We'll just have to wait and see. AMD has been playing catch-up in the desktop speed market, and now their right on the heels of their competition.

I've been waiting for awhile through many good deals on Sandy Bridge to see what Bulldozer would do.

Disappointed to say the least, especially at AMD's releasing something right out of the gate AGAIN that needs fixing and optimization to work on already existing software.

I skipped Phenom I because it was a pig and stuck with older AM2 dual core tech that did a very good job for the price, then upgraded to Phenom II when it intro'd in January '09 and was very satisfied.

Now we have a processor meant more for server applications IMO than desktop... having suffered through delays and mis-marketing only to find out it performs badly in many areas on CURRENT software is not encouraging to say the least.

AMD, I'm NOT a guinea pig...I won't buy a CPU that needs further refinement to realize it's full potential, nor will I buy a "testbed" for future technology.

Get it right like Intel did with Core2, Nehalem and Sandy Bridge, get it right like you did with the old AMD 64 stuff...but don't make statements like " will perform 50% better than i7 and Phenom II" only to have it fail like it did.

Back to Intel I go, for an i5-2500K with stellar performance for $60 US less.

Please explain how running each processor at stock speeds and the highest officially supported memory frequency is "giving an advantage to AMD". Your "real world" comparison is specious since it depends on overclocking both the processor and memory, which only a tiny fraction of users ever do. And, of course, overclocking performance is never guaranteed, which is why no review site out there tests CPUs the way you think they should be tested.

Agreed. Nothing wrong with showing a comparison of standard spec speeds. Furthermore, I fail to even see the sense of matching speeds, as if they are equivalent architectures and pipelines. Running the 2500k at 3.6 is an overclocked case, so why should I stop the FX-8150 at a measely 3.6? Would it be unfair for me to run it at 5GHz under a water loop if the 2500k doesn't make it that far?

I think this article did an adequate job of showing that the 8150 is barely a 2500k competitor, and in my humble opinion, far overpriced for that reason. AMD usually had the edge in performance/$. In that case, it should be priced below the 2500k, not above it. Looks like they are hoping the marketing advantage of calling it an 8-core will win over the poorly informed. At this rate, I'll be buying Ivy Bridge to replace my Phenom II.

If not going to Bench then at the same speed why not bench against the closest comparable speed (GHz) chip? The 2600K is closer and the 2700K is closer yet, yet both would utterly put the Dull Dozer to shame, these are all unlocked CPUs so why NOT show them at an equivalent 'speed'.

"overclocking both the processor and memory, which only a tiny fraction of users ever do"

Be sort of stupid to buy a 2500K if your not going to OC it, even most that buy the stock 2500 use turbo charge to OC it, which is OCing. Further if it doesn't matter (OCing), why have a section of the review on just that.

"What, you want I should rag on them some more?"

Were't they advertising the Dozer as the chip that would equal or better Intel's chips, yet they are still behind Sandy Bridge, even further behind Sandy Bridge E and Ivy Bridge is around the corner. If AMD put a little more money into R&D and developed a good MC (Memory Controller) they'd have a much better product, but then too prices would go up, and as is with the Dozer the PP (price point) is already yto high for the performance delivered....which is why it is Dull

I'll try again, although I suspect it will be futile...

We test CPUs at their stock clock speeds with their highest officially supported memory speeds, because that's what the manufacturer guarantees they'll work at. 95+% of any CPU's sales are in pre-built systems like Dell, HP, etc. that are not only never overclocked but in most cases CAN'T be overclocked.

We overclock the CPU being tested to get an idea of the extra performance an enthusiast can unlock. Results are never guaranteed and a comparison of overclocked speeds of all CPUs might be interesting to some people but would have virtually no ral-world relevance.

And, for what it's worth, AMD never advertised the Bulldozer as something that would "equal or better Intel's chips." I spent a full day in Austin at AMD's Bulldozer tech conference and the most they said is that it would be performance-competitive with the 2500K, which it is.

Really? Sounds like you are not very good at shopping for (or comparing) components. The $270 FX-8150 is the best chip AMD can currently field, which is matched in performance by the $220 i5-2500k. So clearly the Intel CPU does not cost $600. In fact, in this specific case, Intel actually offers a price advantage. If you are buying a $600 Intel CPU, the performance would be far greater performance than the 8150. Even if the Intel Motherboard is a little more expensive, the fact that the processor is $50 cheaper offsets that price difference.

Now, if you are talking about the Phenom II line of chips, I agree there are incredible bargains to be had. The 955 is a great value! But in terms of performance, it is not competitive. As always, its a matter of picking the components for the job at hand. If speed is what you need, Intel is the only game in town. If you want value, the OLD AMD lines are great bargains, but this new FX line is, imho, priced completely incorrectly. The FX-8150 should be cheaper than the 2500k, not more expensive.

For professional video editing, transcoding, and highly computational tasks, price increases can be made up for with increased productivity. Just because the performance is good enough for entertainment purposes doesn't mean it is good enough for all purposes. Viewed through that lens, Intel is the only option for increasing performance beyond the 8150/2500K level.

And if it makes any difference, I am writing this from an Opteron 165, my main desktop is a Phenom II 955, and my mobile device is an E-450. But at this rate, my main desktop will be getting an Ivy Bridge update in the coming year, unless Piledriver is something that competes. That computer I use for extreme multi-tasking over 3 monitors worth of running programs, as well as Folding@home when I am away. So I have often hit with wall with my 4GHz trusty old Phenom. I'd have dropped in a FX series upgrade but my motherboard is only AM3 and does not support that chip. I'll need a new motherboard either way, so I'll most likely make it something LGA1155.

I look at it as a marketing blunder as well as a design issue. The definition of a what constitutes a core is debated to begin with. When they market the 8150 as an 8-core CPU and it generally performs worse than a 4-core 2600K, many people will see this as 4-cores beating 8-cores. Had it been marketed as a quad core with an AMD branded version of hyper-threading, it might have looked like less of a disaster. I don't think it's a BAD CPU, but, given all the hype and anticipation, it is a let down to be sure. I have placated myself by looking at it as AMD's answer to HT, and not as AMD's attempt to overtake Intel in the performance desktop space, although, I think this CPU would do well enough in the more heavily threaded applications I often work with and it might do well in servers. Can anyone direct me to any kind of indication how these chips run on Linux powered machines, just out of curiosity?

The FX-8150 is really just a repurposed Opteron processor (in the same way that the Sandy Bridge Extreme CPUs are repurposed Xeons). Servers have different workloads than consumer systems, and benefit more from the parallelism provided by multiple cores. Consumer machines tend to run less highly threaded applications and benefit more from high instructions per clock and high clock speeds.

Given the growth of "the cloud", it's not surprising that Intel and AMD are putting so much effort into server processor design. But remember both companies have very strong consumer CPUs: Intel's original Sandy Bridge and forthcoming Ivy Bridge processors, and AMD's "Fusion" CPUs (even if enthusiasts sneer at them, Fusion CPUs are perfect for 90+% of the market).

All that said, I do think your idea of introducing the FX-8150 as a four-core CPU with some AMD brand of Hyper-Threading would have been a great idea for AMD.

I think the reason for people being disappointed is the hype. There's always been a bit of fanboi-ism between amd and intel camps with the release of each new chip. People couldn't just be happy to wait and see how everything played out, they jumped on the hype train and missed the target by quite a bit. Just like intel got dumped on for the prescott design, it's amd's turn. Wasn't too long ago i recall all the amd fanboi's strutting around bragging on bulldozer, how it was going to wipe the floor with sandy bridge. Now having to accept the harsh reality is a bit rough to swallow for them.

Real world benchmark test. All the reviews I have read use a configuration for Intel and AMD and the same test are run in a single process environment gathering data for the results. Then either one or the other wins. I would like to see a benchmark test of Handbrake running in the background rendering a HD movie to HardDisk. On my current system this takes about an hour. Then, running these other benchmarks program in the foreground. Then compare the numbers. This would represent a realworld test of multitasking. I personnaly like to run Handbrake rendering my HD movies to Hard Disk. And play games or surf the web at the same time. My current Intel 4 core processor struggles with this. This is the prime reason I have been considering the AMD Bulldozer. All the reviews says it is better at mutlitasking while the Intel I5 is generally faster. Which one is better at multitasking?

Thanks for you comments. I think if anyone check they would find the average user these days are multi-taskers on their computers. They would also find these people are the majority of the consumer market. The gamers need a jet that will do machII, the casual user needs a Hundi to surf the internet, and the multi-taskers need 3 jets that will almost do machI in three different directions at the same time from one machine. Most buy more computer than they need or upgrade to something that is very powerful but won't accomplish what they really want. Primarily becasue all these review are based on the GAMER who OC's and wants to achieve MachIII from his MachII machine.

Hi Jerry

good theory but i'm a gamer who wasn't interested in multitasking i've built a FX bulldozer 8120 Radeon HD 6950 2gb ddr5 16 gb ddr3 1666 mhz. and as it turns out since I've been able to multitask I've been using this machine to much more of its capability the thing is though i could have installed the I5 and i suspect though on a whole it doesn't perform as well as the bulldozer i wouldn't be able to see any differentiating results. I'm a gamer and by rights I should have bought an I5 however I'm also english which means i love the underdog I cannot resist an heroic second lol. It doesn't matter whether you buy a FX 8120-8150 I5 or I7 the chances are you will love the result for what you want to do just do me a favour and chuck 1000w minimum psu in and 16gb of ddr3.

Well Stoney the gamer turning/turned multi-tasker, thanks for confirming my theory and welcome to the multi-tasking world. Thanks also for confirming my gut feel that the bulldozer is better at multi-tasking. I built this machine in 97, its a triple sli with triple gt580s and the intel core 2 quad 2.66. It is a jet that does machII. And, you are right about the video gaming card. This machine just doesn't multi-task very well when I crank up Handbrake. Most people use Prime95 to stress test their machine, but it won't run this machine @ 100% capasity constantly for an hour. I use Handbrake to stress test this one. By the way I don't think the bulldozer is the underdog, I just think AMD is not marketing it correctly. If they would start showing off its multitasking abilities, instead of trying to compete with I5/I7 speed, they would do alot better on the market.

Well im definitely still a gamer i just with all my previous systems i was laboriously shutting down anything that may interfere with the system performance while i was gaming and now I've set up with dual monitor i'm finding no end of multiple uses for this system and at no point does it over stretch itself. Also the Windows 7 update from microsoft that uses (SMT) correctly gives between 1 - 5 % increase in performance across the board and they're expecting another 10 - 15% when programmers start using it. And yes i think your right about AMD's marketing they have been incredibly focused on beating Intel however most bench-tests i've seen the new I7 is miles ahead however its also around 850 pound a chip.

Yea, I was in denial about a year and half ago, thinking I was a gamer. That's why I upgraded to the triple sli gt580's, so I could take as much load as possible off my cpu while gaming. Just so I wouldn't have to shut down other processes. Then about a year ago when I started downloading my dvd's for my htpc's and had to stop my gaming for these processes. I finally realized Iam a multitasker that loves to game. Anyway I appreciate all the info on your bulldozer experience, it has helped alot.

Cheers for this i've learnt more about CPU's in this last couple of weeks than at any other time in my life (pretty sure i could design one now lol).

looking at pc format issue 261 the FX 8150 beats the I5 on every benchmark test except FPS in gaming where the I5 only just takes the lead, according to these graphs the only processors better is the I7. For what you want to do the FX8150 is perfect and an excellent price to boot.

I have the FX 8120 and i have to say i do use it for gaming and i find it amazing at multitasking I can run Battlefield 3 with as many programs as i want running in the background and the system has never got over 50% cpu usage.

50% on each core? How do you explain then that it run with 1 to 2 more fps with HT disabled on i7 cpu's?

Hey Manu

very true it is GPU intensive you are right however modern games do use a hell of alot of cpu power as well they have to network they usually need something horrible like steam to run (which eats resources) they have to handle predictive technology which lowers the lag problems these things and many more use cpu power rather than gpu then you run loads of other entertaining things on your second monitor and the draw increases. I understand what your saying but the only thing (and its a biggy) that the gpu does is run your output.

With the upcoming price drops coming for the FX, these AMD chips are a great deal for Lightwave users. Rather than rendering a single frame at a time with multiple threads, you are far better off running a separate screamernet instance (rendering app)for each. You render 8 frames at once and push each core to 100%.

# Just to state a FACTJusta reader 2012-03-02 03:31
As many people have said and or complained about the AMD vs Intel issues with prices and performance, not sure if anyone has really pointed it out, and I do not know everything nor am I a wise guy, but just to state a fact to everyone out there so everyone knows and understands, Quote from Wikipedia "AMD licensed its x86-64 design to Intel, where it is marketed under the name Intel 64. As Intel licenses AMD the right to use the original x86 architecture (upon which AMD's x86-64 is based), these rival companies now rely on each other for 64-bit processor development.Should this agreement collapse, AMD would no longer be authorized to produce any x86 processors, and Intel would no longer be authorized to produce x86-64 processors, forcing it back to the x86 architecture. However, the agreement provides that if one party breaches the agreement, it loses all rights to the other party's technology, while the other party receives perpetual rights to all licensed technology. In 2009, AMD and Intel settled several lawsuits and cross-licensing disagreements, extending their cross-licensing agreements for the foreseeable future and settling several anti-trust complaints."

My opinion would be that Intel may have to charge more because of some of this but AMD should get some credit. And most of us probably could care less about a 32 bit, (if you ask me - they should be extinct!) but where would Intel be? AMD could Rule!
Anyway- everyone thank AMD for that bad ASS I5 2500K, it should have the name AMD on it, I am sure they both deserve credit, and two good ideas made what we have now. AMD makes their own processors more than likely while Intel takes a good AMD and soups it up with their works. Maybe!.

Benchmarks really do not show what this processor can do, they did not on my old Opteron, however when my friends came round and saw what I did on that machine, compared to there core duos...

As the review notes, I used the SpecAPC Lightwave script. This script runs a standard Lightwave installation and was developed in co-operation with Newtek. According to the description of the benchmark, "The benchmark puts special emphasis on processes that benefit from multi-threaded computing, such as animation, OpenGL playback, deformations, and high-end rendering that includes ray tracing, radiosity, complex textures and volumetric lighting." In my own experience it seems to keep the cores pretty busy.

If you're really interested, you can download the trial version of Lightwave and the Spec APC scripts and run the benchmark yourself.

First off i am running the 8120 not the 8150 but i have it over clocked to 4.8 and my scores running these test r high some over 10 to 15% higher then his over clock for one i am using the standard 2133 not the 1869 memory thats what amd said to use not the 1869 so dont know where u r getting this but still i run cinebench at 8.05 and alot of my aida64 extreme edition sores r higher to have not done any coding test but i well i soon as i can find the free ones but still i thing alot of these sights r running memory lower then what amd is calling for and that why some of these test r coming up different then what i have so run some benchmarks using the recommeded memory please i have yet to see a website run ddr3 2133 on the chips thanks

That makes 2 of us, however remember these were done AGES ago, no fixes or bios updates, it makes a HUGE difference updating the bios...

Have you done that?

As another reader explains, these tests were done with an early production motherboard from ASUS with a very early BIOS. It's likely the scores would be higher now that vendors have had some months to fine-tune them.

However, I'm puzzled by your assertion that AMD "said to use" 2133MHz memory. 2133MHz memory is hardly standard, and AMD certainly doesn't "recommend" it, since the highest DRAM frequency their 990FX chipset officially supports is 1866MHz.

I know that some motherboards support very high memory frequencies, but you said that AMD specifically said to use that frequency, and as far as I know they've never said that.

Your messages would be much easier to understand with punctuation...

# My Intel 2700k vs My AM3+ 8150Christopher Fields 2012-05-16 01:52
I actually can't tell the difference when it comes to day to day activities between the two. They both game great and they both are fast. One thing I like over my AM3+ Board is that the Intel Z68 chipset offers HDD+SSD Hybrid and it does make a difference. I am currently using a 256gig SSD and I have allocated 64gig SSD Cache for my Samsung 2TB HDD and the bench mark shows it to be about 2.5 times faster. I can trasnfer a full 9gig movie file in about 6 seconds :) and that makes me happy. 1 thing I like about my AM3+ board is that there is more 6gb SATA ports and more USB options on my motherboards. IMO, both offer great things the only gripe I have is that my 8 core processor should be giving my 2700k a run for its money and its not. But in the end, I am happy.

# Love it...Joe 2012-06-10 21:12
I built an AMD based system with the FX-8150 at the heart of it all and I must say it turned out really nice. I use an ASUS M5A88-V EVO MB and have 8 GBs of 1866MHz (PC14900) RAM with a GTX 560 Ti FTW for the GPU. I use a cheaper heat sink, the Cooler Master Hyper 212, but I achieve great temperatures even when it's under a load. I can multitask to my hearts content and even run multiple HD games at the same time. I am impressed for less than 1,100 USD.

A year earlier I helped a friend build an intel based system with the i5 2500K processor. We used a P67 Revision 3 MB I believe. It has 8 GBs of 2.0GHz RAM but only uses a GT440 Series GPU. It can play all the games at high res with full detail just like mine. The only difference is, his system cost over 1,400 USDs to build. We searched Google Shopping, did all the comparisons and made sure to get the best price. His processor and MB were the most expensive items and were far more pricier than my MB and processor.

I believe that when it comes to personal gaming, AMD takes it with the FX-8150. It just had the price that everyone is looking for. If you are a loyal Intel fan and have the money to spend then you ARE making a good choice but for those of us who work for a living...we need those savings...period.

# This Chip is Awesome!Mike Meredith 2012-08-14 10:03
I'm running an Asus Crosshair MB with the 8 core Bulldozer and 32 Gigs of Ram! This chip is hyper threaded to 16 core, so no wonder it has room left over! I use it for Gaming and everything else I can throw at it and I haven't had any problems! I really don't put much weight into these tests they put on this chip because we really don't know the environment and testing conditions. Each test may be different from another, so all of you guys that are disappointed; unless you have the chip and know what it can do, then don't be. You really have to own it to know!

I'm glad you like your system, but the Bulldozer is in no way "Hyper threaded" and does not show 16 cores to the OS. Hyper threading is an Intel technology, and AMD does not use it, nor do they have anything like it.

# Dude. Really?James Roberts 2012-08-16 23:34
Ok. You perform tests on page 14 of this review where you say you enabled single 'core' comparison, but disabled part of the AMD core! That's not even CLOSE to a single core comparison. The AMD 'core' is able to process 2 threads in real time instead of Intel's hyperthreading which uses a virtual thread. It's called BIASED offset, and is kinda like cheating. I am a DIEHARD Intel fan, but you are totally biased as hell against AMD. I do not care about what you claim as your professionl symbolism to 'uphold unbiased benchmarks', but for sure, I'm not going to use this site as a reference anymore simply because everyone is biased as hell round here. Thanks for the benchmark regardless.

and btw, you must compare architecture performance in all areas in order to perform an unbiased comparison. The runing of single threads in single cored capable of running multiple threads is really like comparing apples to oranges. Especially considering the new architecture is what makes the processor different.

Well, James, I suppose as a programmer with 30 years' experience I could engage you in an argument of precisely what constitutes a "core", but there are two points I think would make the case better than I can.

Point 1: AMD disagrees with you. That's why they promote the FX-8150 as an "eight core processor" rather than the "four core processor" it would be if they thought a Bulldozer module was a core as you do.

Point 2: Software disagrees with you. Single-threaded code will not magically re-arrange itself to run on the two integer execution units of a Bulldozer module; it will run on just one. Nor is there any setting or configuration you can tweak to make this happen.

No benchmark in the world will run on one Intel core and yet spread the load to run on all the resources of a Bulldozer module. And if such a benchmark did exist, it would be useless, since no other software works that way.

David, he's saying the whole single core comparsion is just retarded because in a 8-core optimized application, you can use 8 threads without juggling. And I'm guessing you haven't gotten very far in that 30 years of programming because I have 10 years and i'm already using more than 4 threads a couple of years ago.

# RE: RE: RE: ...again...David Ramsey 2012-09-28 16:01
Wow, did you miss the point. Lemme try again:

Regardless of the doubtless wonderful code you're cranking out, the fact is that most consumer application code remains (primarily) single-threaded. This means that single-core performance is currently the most important aspect of CPU performance.

This is why it's important to compare single-core performance of the FX-8150 against Intel processors. I don't see why this is so hard to understand.

Of course any modern OS keeps dozens of threads going, so a multi-core CPU can help system responsiveness even if individual applications don't run any faster. AMD used to beat this drum when the weakness of their single core performance relative to Intel was brought up, but I haven't seen them do it lately.

what are you talking about? so you are saying consumer applications need the full power of i7 right now? 30 fps that's invisible to the naked eyes or around 40% increased performance on 8-core applications? I love the people who just get excited watching text on the screen that says 140 fps compare to a 110 fps machine. They really really make me laugh.

At the end of the day, look at the benchmarks: on average, the FX-8150 is slower than the 2500K, which has only half the cores, _because its per-core performance sucks_. Even in heavily threaded applications that scale linearly with the number of cores available, like CINEBENCH, the 8-core AMD chip can barely beat the 4-core Intel chip.

Again, just look at the benchmarks. I ran a lot of them, and the performance trend is very clear. AIDA64, CINEBENCH, SPECviewperf, SPECApc, media encoding, POVRay, Blender....all heavily multithreaded, and the FX still can't pull decisively ahead.

Performance isn't everything, of course. The FX platform has a lot more PCI-E lanes, and six native SATA 6G ports, so that's something to keep in mind.

And while the 8150 was $254 when I wrote this review, it's currently selling for $189 at Newegg...which should also tell you something: the 2500K price is actually _up_ a few dollars in that same time period.

At end of the day anybody that knows their stuff should conclude that FX-8150 is better with those numbers. Due to the fact that nothing in the market can make the difference between the i-series and FX's on a single-core useful, useless they only runs benchmarks or starts and shutdown their computers all day. It's like buying a gas-hog vs a prius, except there's no road that allow you to accelerate or go that fast in this case.

I refuse to just stare benchmark numbers all day and conclude that one processor is better than the other without thinking about what it actually mean. And thanks for people hyping the benchmark numbers in the wrong section, great cpu like the FX-8150 doesn't get as a great of sales number.

But I do appreciate for the numbers that people should really care about, if they actually considering about usage.

Ok I am an official AMD reseller. What does that mean, means I get all the information that most people, even on sites like these do not get. AMD have admitted this processor is NOT as fast as they were hoping it would be, however what they have said. If you want a processor that can multitask then this is the processor for you. You can have 15 to 20 programs open, and it will not bog down, like some Intel proessors do. AMD have always led the way in multitasking, which is why, with Windows 8. This processor is the one to buy.

# RE: again...David Ramsey 2012-10-02 08:48
I dunno, Kirk...they tell us quite a lot. Last year, when Bulldozer was introduced, AMD flew me and a bunch of other reviewers to their Austin facility, where we received a full-day technical briefing on the new CPU. Not only were there the expected marketing people, but we also got detailed technical presentations and talks from project leaders and CPU architects. (There was also an impressive overclocking demo using liquid helium, because LN2 is for weenies.)

There were relatively few benchmarks, though, and no single-core benchmarks. In fact we were specifically asked not to run any single core benchmarks on the demo machines they had available.

We did get the "AMD CPUs excel at multitasking" spiel. This may well be true, but the problem with this claim is that it's very hard to quantify repeatably. I can run synthetic and real-world benchmarks all day long, and get repeatable results, which I can then use to compare the performance of the items I'm reviewing. But trying to quantify something like "System responsiveness seems better with the Bulldozer when running 18 background tasks" is kinda hard. How hard? Well, when asked, AMD couldn't offer a specific test scenario that would show this in a consistent fashion.

While I'm not an AMD fanboy per se, I still use the system I built to test this processor. It's outfitted with 8GB of AMD Black Edition qualified memory and a bespoke XSPC water cooling system, all in an AMD-themed Cooler Master HAF case I reviewed a couple of years ago. It's a powerful and visually impressive system (LED lightning, don't you know). It's overclocked and much faster than most user's machines, and I have no complaints at all about its performance, nor would almost anyone else.

That still doesn't change the fact that a system based on the Intel 2500K would be just as fast if not slightly faster, and with a higher spec Intel CPU, or an overclocked on, there would be no contest.

With the price cuts on Bulldozer it arguably has more bang for the buck than Intel, and things like the extra PCI-E lanes and SATA 6G ports a Bulldozer system offers are other things to consider. But there's no point in pretending that Intel doesn't decisively own the performance crown.

Kirk: we certainly appreciate your feedback, but I find your comment more than just a little condescending. Not only do I operate this website, but I am also an authorized AMD partner for my computer company. I can tell you first hand that you're getting the lightest possible marketing fluff from their sales team, and we're getting technical data that goes far beyond that. Furthermore, when you come and leave comments that downplay our knowledge on a topic in comparison to your superior sales experience, it's best to add some supporting facts and citation to back up your point.

I was not having a pop at the review, more at the people coming on here with facts and figures that cannot be true. We all know its a slower processor, however it is better for multitasking, then some other processors at the same speed. This has been proven...

For an all round gaming package you cannot beat an AMD machine. And its a lot cheaper to!
