Intel (SKU) Specifications

Intel's initial Haswell CPU line comprises 7 mobile processors, 6 Core i7 desktop processors, and 7 Core i5 desktop processors, with Core i3 versions coming later. With the desktop CPUs at least, Intel's numbering scheme is more consistent: all Core i7 CPU have model numbers of the form 47xx, while all Core i5 CPUs have model numbers of the form 45xx and 46xx. As before, "K" series CPUs have unlocked multipliers for overclocking, while "S" and "T" series CPUs emphasize low power usage.

Here are some representative models from the new (desktop) Core i5 and Core i7 lines:

MSRP $339.00 $303.00 $303.00 $242.00 $213.00 $213.00 $313.00

Look at the specification of the new Core i7-4770K compared to last year's Core i7-3770K (the last column in the chart). TDP is up from 77 watts to 84 watts, graphics maximum frequency is down from 1350MHz to 1200MHz, and the graphics core is the new HD4600 with 20 "execution units" as opposed to last year's HD4000 with 16 "execution units". But that's about it for the differences. Cache, supported memory frequencies, base and boost clocks...they're all the same. Now, this is not to say that there aren't more differences:

  • Intel has beefed up their Advanced Vector Extensions, doubling per-core performance for both single and double precision arithmetic as compared to Sandy Bridge.
  • New power optimization features can control power use by the entire system, not just the CPU (of course this is most important for the mobile CPU line)
  • The officially supported display resolution for the iGPU of desktop processors has increased to 3200x2000 for DisplayPort devices and a full 4K (4096x2304) for HDMI devices, although the press deck lists the refresh rate for this mode at a mere 24Hz.
  • Some mobile CPUs have embedded DRAM (eDRAM) on-die to support "Iris Pro" graphics, which Intel claims will double graphics performance for mobile systems.
  • There are more differences if you compare the entire Core i5/i7 lineups. The top-end HD4600 graphics is spread across virtually all of the desktop processors (the Core i7-4700R gets "Intel Iris Graphics 5200"), and other features like virtualization and Gen 3 PCI-E lanes are common to all as well.

MSRPs-- well, technically, they're "tray" prices for 1,000 pieces-- are up slightly: $26, or a bit less than ten percent, in the case of the 4770K vs. last year's 3770K.

In the next section I'll look at what's new in the Haswell architecture, as well as taking a look at its supporting Z87 chipset.

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.

# GPU.alfie 2013-06-01 11:32
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
