Choosing a Gaming CPU October 2013: i7-4960X, i5-4670K, Nehalem and Intel Update
by Ian Cutress on October 3, 2013 10:05 AM ESTSleeping Dogs
Sleeping Dogs is a strenuous game with a pretty hardcore benchmark that scales well with additional GPU power when SSAO is enabled. The team at Adrenaline.com.br is supreme for making an easy to use benchmark GUI, allowing a numpty like me to charge ahead with a set of four 1440p runs with maximum graphical settings.
One 7970
With one AMD GPU, Sleeping Dogs is similar across the board.
Two 7970s
On dual AMD GPUs, there seems to be a little kink with those running x16+x4 lane allocations, although this is a minor difference.
Three 7970s
Between an i7-920 and an i5-4430 we get a 7 FPS difference, almost 10%, showing the change over CPU generations. In fact at this level anything above that i7-920 gives 70 FPS+, but the hex-core Ivy-E takes top spot at ~81 FPS.
One 580
0.4 FPS between Core2Duo and Haswell. For one NVIDIA GPU, CPU does not seem to matter(!)
Two 580s
Similarly with dual NVIDIA GPUs, with less than ~3% between top and bottom results.
Sleeping Dogs Conclusion
While the NVIDIA results did not change much between different CPUs, any modern processor seems to hit the high notes when it comes to multi-GPU Sleeping Dogs.

It's not really representative of most games, everyone knows it's highly CPU limited...Most games are GPU limited as proven by this, yet a lot of people seem unaware of that.Spoelie - Thursday, October 3, 2013 - link
Another choice I was considering for gaming: the i5 3350p.This is the cheapest i5 available on this side of the pond and still Ivy, so it allows the 4 bin overclocking. Since haswell, intel does not allow any overclocking anymore for non-K parts.
In addition, Z77 motherboards are quite a bit cheaper than Z87 for the moment.
So for a 30$+ cheaper than the 4430, you get 3.7/3.6/3.6/3.5ghz Ivy vs 3.2/3.0ghz Haswell.
The platform isn't that upgradeable but with Intel moving to 2-year cadences for desktop upgrades, the performance should stay relevant for at least 4 years...

Amazing article, Ian. Thanks a ton.It's shocking to see how well the dual core Intel parts and the two-module AMD chips fare, even at 1440p with a single GPU. With respect to single-GPU gaming, opting to pull some $ out of the CPU/MB fund in order to buy a better GPU is certainly more advisable.
Those who invested in the X58/1366 platform certainly got their money's worth. Frankly, even buying a secondhand 1366 platform is a good idea if it's cheaper than a new quad-core 1155/1150 + mobo. Going from an SSD running on 3GB/s to 6GB/s really isn't noticeable. I've done this twice on two separate platforms and the only difference I've seen is with respect to bootup speed.
You also have to figure that this graph will change with the newer generation of console ports. I have an inclining that 2/4 threads might stumble a bit with some more demanding titles. We might even see AVX play a more significant role as well

BF4 is gonna bump me from X58 I believe... way more CPU bound than BF3 (1920x1200@4.2ghz)snouter - Wednesday, October 30, 2013 - link
BF4 makes my 4930k work more than I thought it would.BOMBOVA - Friday, October 4, 2013 - link
i am reviving my x58 MSI board, with Syba sata 3 controller, and i really notice a difference on my long video editing files. that was my whole point of modding up. Cheers. good discussionchizow - Thursday, October 3, 2013 - link
I really appreciated what this article tried to accomplish, and I think it does shed some light on some aspects of what you were trying to test...but someone at AnandTech couldn't throw you a bone and get you a pair of higher-end GPUs to test? 580s are a bit long in the tooth to garner any meaningful results. Maybe Gigabyte could have kicked a pair of 680s to you?Also, it would have been nice to see some Battlefield 3 results, since it is widely touted as a title that scales extremely well with both CPU (and shows big differences with HT) and GPU, especially in MultiPlayer, and will be especially relevant in the next few months as Battlefield 4 launches.

I find testing for CPU performance is not a strong suit of reviewers. The test has lots of data but it is missing the situations that gamers end up in which do require CPU performance.Starcraft 2. Just run a replay of an 8 player map at 4x-8x speed and most dual core notebooks practically break down.
Total War set unit size to epic and run some huge battle. That is where this games is great but it drains cpu resources like crazy.
Shooters or racing games are examples where the CPU has to do nothing but feed the GPU which is really the least CPU intensive stuff. Mulitplayer adds quite a bit of overhead but it is still not something if you play you need to worry much about your CPU.
When testing CPU performance kick all those shooters to the curve and focus on RTS games with huge unit sizes.
It is the minimum frames at these games that require CPU performance. The situations where it gets annoying that in the biggest battles the CPU cannot keep up. Starcraft 2 on medium runs on almost any GPU but it can bring slower CPU quickly to its limits.

COH2 is planned for our next benchmark update to cover the RTS side. I know Rome II is also a possibility, assuming we can get a good benchmark together. As I mentioned, if possible I'd like to batch file it up so I can work on other things rather than moderate a 5 minute benchmark (x4 for repetitions for a single number, x4-8 for GPU configs to complete a CPU analysis, x25+ CPUs for scope).If you have any other suggestions for the 2014 update, please let me know - email address is in the article (or click on my name at the top).

"COH2 is planned for our next benchmark update to cover the RTS side."Excellent. This is one of my most-played games. In addition, I wouldn't be surprised if subsequent patches for this game didn't noticeably improve it's multi-threaded performance, so having older results will be nice to have once these patches are released in order to track the improvements.
