Choosing a Gaming CPU at 1440p: Adding in Haswell
by Ian Cutress on June 4, 2013 10:00 AM ESTSleeping Dogs
While not necessarily a game on everybody’s lips, Sleeping Dogs is a strenuous game with a pretty hardcore benchmark that scales well with additional GPU power. The team over at Adrenaline.com.br are 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
Sleeping Dogs seems to tax the CPU so little that the only CPU that falls behind by the smallest of margins is an E6400 (and the G465 which would not run the benchmark). Intel visually takes all the top spots, but AMD is all in the mix with less than 0.5 FPS splitting an X2-555 BE and an i7-3770K.
Two 7970s
A split starts to develop between Intel and AMD again, although you would be hard pressed to choose between the CPUs as everything above an i3-3225 scores 50-56 FPS. The X2-555 BE unfortunately drops off, suggesting that Sleeping Dogs is a fan of the cores and this little CPU is a lacking.
Three 7970s
At three GPUs the gap is there, with the best Intel processors over 10% ahead of the best AMD. Neither PCIe lane allocation or memory seems to be playing a part, just a case of threads then single thread performance.
Four 7970s
Despite our Beast machine having double the threads, an i7-3960X in PCIe 3.0 mode takes top spot.
It is worth noting the scaling in Sleeping Dogs. The i7-3960X moved from 28.2 -> 56.23 -> 80.85 -> 101.15 FPS, achieving +71% increase of a single card moving from 3 to 4. This speaks of a well written game more than anything.
One 580
There is almost nothing to separate every CPU when using a single GTX 580.
Two 580s
Same thing with two GTX 580s – even an X2-555 BE is within 1 FPS (3%) of an i7-3960X.
Sleeping Dogs Conclusion
Due to the successful scaling and GPU limited nature of Sleeping Dogs, almost any CPU you throw at it will get the same result. When you move into three GPUs or more territory, it seems that having the single thread CPU speed of an Intel processor gets a few more FPS at the end of the day.

Hi Ternie,To answer your questions:
(1) Unfortunately for a lot of users, even DIY not just system integrators, they leave the motherboard untouched (even at default memory, not XMP). So choosing that motherboard with MCT might make a difference in performance. Motherboards without MCT are also different between themselves, depending on how quickly they respond to CPU loading and ramp up the speed, and then if they push it back down to idle immediately in a low period or keep the high turbo for a few seconds in case the CPU loading kicks back in.
2) This is a typo - I was adding too many + CPU results at the same time and got carried away.
3) While people have requested more 'modern' games, there are a couple of issues. If I release something that has just come out, the older drivers I have to use for consistency will either perform poorly or not scale (case in point, Sleeping Dogs on Catalyst 12.3). If I am then locked into those drivers for a year, users will complain that this review uses old drivers that don't have the latest performance increases (such as 8% a month for new titles not optimized) and that my FPS numbers are unbalanced. That being said, I am looking at what to do for 2014 and games - it has been suggested that I put in Bioshock Infinite and Tomb Raider, perhaps cut one or two. If there are any suggestions, please email me with thoughts. I still have to keep the benchmarks regular and have to run without attention (timedemos with AI are great), otherwise other reviews will end up being neglected. Doing this sort of testing could easily be a full time job, which in my case should be on motherboards and this was something extra I thought would be a good exercise.

It is sad to poor journalism in the form of excuses in an otherwise excellent article. :-/1. Any review sites that make excuses for why they ignore FCAT just highlights that they don't _really_ understand the importance of _accurate_ frame stats.
2. Us hardcore games can _easily_ tell the difference betwen 60 Hz and 30 Hz. I bought a Titan to play games at 1080p @ 100+ Hz on the Asus VG248QE using nVidia's LightBoost to eliminate ghosting. You do your readers a dis-service by again not understand the issue.
3. Focusing on 1440 is largely useless as it means people can't directly compare how their Real-World (tm) system compares to the benchmarks.
4. If your benchmarks are not _exactly_ reproducible across multiple systems you are doing it wrong. Name & Shame games that don't allow gamers to run benchmarks. Use "standard" cut-scenes for _consistency_.
It is sad to see the quality of a "tech" article gloss and trivial important details.

Judging by your excellent command of English, I don't think you could identify a decent technical article if it slapped you upside the head and banged your sister.Razorbak86 - Tuesday, June 4, 2013 - link
LOL. I have to agree. :)Michaelangel007 - Wednesday, June 5, 2013 - link
There is a reason Tom's Hardware, Hard OCP, guru3d, etc. uses FCAT.I feel sad that you and AnandTech tech writers are to stupid to understand the importance of high frame rates (100 Hz vs 60 Hz vs 30 Hz), frame time variance, 99 percentile, proper CPU-GPU load balancing, and micro stuttering. One of these days when you learn how to spell 'ad hominem' you might actually have something _constructive_ to add to the discussion. Shooting the messenger instead of focusing on the message shows you are still a immature little shit that doesn't know anything about GPUs.
Ignoring the issue (no matter how badly communicated) doesn't make it go away.
What are _you_ doing to help raise awareness about sloppy journalism?

Why doesn't this long article include AMD's latest APU, the Richland 6800K? Heck you can even buy it now on Newegg.ninjaquick - Tuesday, June 4, 2013 - link
The data collected in this article is likely a week or two old. Richland was not available at that time. It takes an extremely long time to do this kind of testing.DaveninCali - Tuesday, June 4, 2013 - link
Richland was launched today. Haswell was launched two days ago. Neither CPU was available two weeks ago. It all depends on review units being released to review websites. Either Richland was left out because it wasn't different enough from Trinity to matter or AMD did not hand out review units.majorleague - Wednesday, June 5, 2013 - link
Here is a youtube link showing 3dmark11 and windows index rating for the 4770k 3.5ghz Haswell. Not overclocked.Youtube link:

Ian, in the table on page 2 there's a mistake: the Phenom II X4 960T has a stock speed of 3 GHz (you listed 3.2 GHz) and it does turbo up to 3.4 GHz.
