Core i7-4770K Conclusion

Core i7-4770K Overclocking

The 4770K's Haswell architecture re-introduces the concept of base clock overclocking, the classic overclocking mechanism which Intel removed starting with Sandy Bridge. While Intel's press materials are (as usual) devoid of many technical details, it looks as if the CPU clock and uncore (things on the CPU that aren't the CPU, like the iGPU, cache, etc.) clocks are now separate. This means that increasing the base clock only overclocks the CPU. In theory you should be able to significantly overclock even non-"K" CPUs, but I'll have to wait to confirm this until I have such a CPU to test. Multiplier overclocking is still the best mechanism to use with "K"-series CPUs, since it preserve's the CPU's ability to clock itself down when extra performance isn't needed. However, you can use base clock adjustments to add sub-100MHz increments to the CPU clock speed if you wish.

Enthusiasts were disappointed in the overclocking ability of the Ivy Bridge CPUs, having expected that the new 22nm fabrication processor and lower power requirements would translate into more overclocking headroom. Sadly, this did not prove to be the case. While 4.8GHz and even higher was possible on a Sandy Bridge-based Core i7-2600K CPU, Ivy Bridge was limited in my tests to 4.7GHz. Any attempts to go higher were met by temperature spikes in excess of 100 degrees Celsius, resulting in severe CPU throttling or crashes. Will Haswell be any better?

Sadly, no. With the maximum multiplier raised to 47 and a core voltage of 1.4V, I could boot into Windows, but the system would crash quickly under most benchmarks. Dropping the multiplier to 46, yielding 4.6GHz, enabled me to run most of the benchmarks, but temperatures would spike (as they did under Ivy Bridge) despite the best efforts of the Thermaltake Silver Arrow cooler with its twin 140mm fans and massive heat sink. Benchmarks like x264HD 5.0 and SPECapc Lightwave would crash the system after a minute or so.

Ultimately the highest speed I could run and still make it through my entire benchmark suite was a mere 4.5GHz; even going to 4550GHz by tweaking the base clock resulted in crashes. I was able to drop the voltage to 1.3v from 1.4v, which kept temperatures under 85 degrees Celsius even under heavy load. Given that Haswell uses the same fabrication process as Ivy Bridge, but is rated to dissipate more power (84 watts as opposed to 77 watts), the lower overclocking limits are perhaps unsurprising. But they're still disappointing. The chart below shows the performance improvement the overclocked CPU achieved on each benchmark:

4770K Stock 4770K OC 4770K Stock 4770K
OCAIDA64 Queen 1.0 1.21 x264HD Pass 1 1.0 1.15

PCMArk 7 Creativity 1.0 1.05 Arcsoft Media Converter 1.0 1.11
PCMark 7 Computation 1.0 1.16 Average Performance Improvement 13.8%

The 13.8% average performance improvement from overclocking is considerably less than the 18% improvement returned by the overclocked 3770K. I suspect that in most real-world scenarios, an overclocked 3770K will provide performance slightly better than an overclocked 4770K.

Overclocking the iGPU was pretty easy: I was able to raise the frequency to 1600MHz from 1250MHz without a problem. Going any faster crashed the display driver, even with voltage tweaks, but the system always recovered.

iGPU Stock FPS iGPU OC FPS % improvement
Unigine Heaven 3.0 18.1 19.6 8.3
Aliens vs. Predator 18.7 20.8 11.2
3DMark GT1 3.2 4.0fps 25.0
3DMark GT2 3.62 4.52 24.9
3DMark GT3 5.54 6.78 22.4
3DMark GT4 2.58 3.18 23.3
Lost Planet 2 6.7 8.0 19.4

Average Performance Improvement

19.2%

The average 19.2% improvement is a good dollop of free iGPU performance.

Overclocking the Haswell Core i7-4770K was ultimately disappointing, but better results may be possible with more exotic cooling methods. Join me in the next section for my final thoughts and conclusion.

No wonder your OC crashed!

"even going to 4550GHz by tweaking the base clock resulted in crashes"

(4th para, pg 12)

Excellent write up David Ramsey. Thank you.

I wonder what TIM was used this time.

I feel this will be a very nice chip for the laptop crew as the GPU is a great step up.
I see nothing to make me shift from Sandy in my desktop, not even in the new chipsets.

I am a bit disappointed.
I will most likely get a new system this year an waited for Haswell (and the Nvidia 700 series), but it does not seem to be a very interesting new product for PC gamers like me.
Currently I have an i7920 with a GTX295.

Any recommendations, ideas, suggestions?
(My new GPU will most likely be the GTX780.)

I'd like to ad that I also thought about buying a Intel Core I7 3820.
Would it be wise to switch to the new socket?

You will see a substantial performance improvement moving from a 920 to a Haswell CPU. As I mentioned in the review, if you've upgrading your platform, there's little reason to spend money on the end-of-life LGA1155 platform unless you can find motherboards and CPUs significantly cheaper than Haswell-based components.

A substantial improvement?
Ok, being a layman that was not quite clear to me.

Is the LGA2011 platform at the end-of-life too?
The i7 3820 is a hundred bucks cheaper than the i74770 and appears to be just as powerful.

Well, I did provide a link to my original Sandy Bridge review, which compared the then-new Core i7-2600K to a Core 2 950. The 2600K stomped all over the 950, so it's a reasonable assumption that the two-generations-newer 4770K would be much faster than a 920.

Yes, a Core i7-3820 will be (for all intents and purposes) about the same performance as a 4770K, except in things that use the integrated GPU like Quick Sync. You would have to buy an expensive LGA2011 motherboard, though. And while the LGA 2011 isn't EOL, it's a more expensive platform overall, and it's not really worth the money unless (A) you really anticipate a need for a six-core CPU in the future, or (B) can really used all those PCI-E lanes. In the meantime you're giving up the advantages of the Haswell platform, like more SATA 6G ports, integrated USB 3.0, and all those fun Intel SSD caching things.

Mr. Ramsey,
Thank you so much for your time.
You've really helped me to decide.
One can read all the reviews one can digest, but for a layman it is very difficult to get a clear view of these complex technical matters.
I might wait a few more months (if I can muster the patience) and then I will opt for a Haswell based machine with a GTX780.

Also, on Newegg right now a Core i7-3820 is $299.99, while the MSRP of a 4770K is $339.99. That's only $40 difference, and you'll probably spend that much more on an LGA2011 motherboard.

It all depends on what you want to do with your machine and is your machine currently meeting your needs. I was considering going with the Haswell upgrade and the GTX 770 but then looked at my usage to see if my machine was being taxed or missing some feature. My answer was, no I am not missing anything. I have the same CPU as you but have a GPU GTX 570. I also had the GTX 295 and when I upgraded to the GTX 570 there was a huge improvement. I also put in an SSD which helped out a bit as well. You also have to remember most games a console ports as well.

My system is foremost used as a gaming computer. I am a heavy gamer. I also work with large databases containing tens of thousands of records.

I noticed that my GTX295 has difficulty keeping up with the latest games. And I want my machine to be able to run games like Metro Last Light, and the upcoming Watchdogs, Batman Arkham Origins, and most of all GTA V etc without any problems.
I read somewhere that my current motherboard would limit the newer much faster videocards like the GTX780 in their data throughput. So I figured I needed a new system.

I would upgrade your GPU first, then investigate what level of GPU will saturate PCI-e2 (a single 780 will not, a 690 might a bit), if you're still not happy with the performance you can upgrade the CPU/board and carry the GPU accross to a new board.

Unless you have cash to burn then just buy the best :D

Just my 2cents.

Thanks. Something to consider... but my current system is so stable and reliable I hate the thought of breaking it up. I don't want to jinks it :). I think I might keep it intact as a backup system.

Theoretically, yes, the PCI-E 2.0 lanes on older motherboards only offer half the throughput of the PCI-E 3.0 lanes on a newer motherboard.

In terms of game playing, though, no current video card can even come close to saturating the bandwidth of 16 PCI-E 2.0 lanes. So a newer motherboard won't help there.

Keep that 920.

I have an i7-2600K that I can push to 4800Ghz.
Can only push the 4770K to 4400Ghz.

But even with both at 4400Ghz, the 2600K is far faster than the 4770K.

I do not play games. I am a developer and I usually compile 24 huge projects at the same time which pushes the CPU to the max.
After I do a 7Zip to all 24 EXEs at the same time again.

The 2600K finishes the same task way faster than the 4770K.

Don't know why but its the disappointed truth.

Have an i7-2600K + Asus P8P67 WS Revolution and now an i7-4770K + ASUS Z87 Deluxe.

Will have to sell this new babies and keep the 2600K.

Hope this helps some of you.

To be honest, the CPU performance is where I expected. On average, we're looking at a minor performance gain of perhaps 5% on average. Also, the reason why power consumption went up is because they integrated the voltage regulators onto the chip itself, so power:performance is not going to go up.

What really bugs me about this is that well, Intel has taken VT-d out of the K series of parts. It's a matter of chasing short term profits for long term gains IMO. Actually, if they wanted enthusiasts to buy Xeons, they could try to sell a "K" series of Xeon cpu.

Then you realize that Intel is a monopoly and that well, they can pull this sort of segmentation off because well, there's nothing the competition can do.

Would this be a big upgrade for me as I have a i5750 Lynnfield cpu.

I do a lot of desktop and programs work on three 1200 res monitors and sometimes the computer slows down . even when transferring files from one hard drive to another it can kill the system.

would I benefit upgrading my system would I see a big upgrade at the same clock speed.

thanks for any advice

# RE: LeeDavid Ramsey 2013-06-02 08:38
My guess would be that the CPU is the least important part of your system as regards performance. After all, transferring files from one disk to another isn't a very CPU-intensive activity, so upgrading to a faster CPU probably wouldn't help.

Without knowing more it's hard to say what the problem is. If you're running an old XP box, it's probably full of crufty software junk. Limited RAM can affect performance as stuff must be continually swapped out to disk, and hard disks themselves could be slow.

For most people, upgrading from a hard disk to an SSD is the single biggest performance improvement they can make. You might want to try this and see if it helps. You can of course always use the SSD if you decide to subsequently upgrade the entire system.

Srory (to set the scene) and then one question I'd like opinions on pls. I also run an i920 and it's currently clocked at 3.8 without breaking a sweat. The only reason I kept it down there is because I don't want my missus complaining about fan noise when she's working on her laptop (and I'm gaming next to her). I was thinking of upgrading my CPU (which would effectively constitute a rebuild with mobo and memory and cpu).

I've had no issues with gaming or working through windows, it was more of an 'upgrade itch'. So in the end I backpedalled out of the rebuild idea. I had been running on my XFX 5870 GPU for the last three and bit years, so opted to put the cash there instead and went for a Vapor-X 7970GhZ. Money well spend imho. I can probably squeeze some more out the i7920 (DO) if I need to, and wait till next year for Broadwell before I rebuild....or at least that's my thinking, and the question is, do people agree with the approach?

The performance of the Haswell at the same clock speed will be substantially better than that of the i920. That said, it's hard to predict how it would affect your frame rates in games. When I compared the 950 to the then-new Sandy Bridge 2600K, overall performance was 35% better on benchmarks, but I didn't do any "game frame rate with discrete video card" tests. The 920 was a great CPU and I think your strategy of going for a video card upgrade was the right one in this case.4jnft
