Choosing a Gaming CPU October 2013: i7-4960X, i5-4670K, Nehalem and Intel Update
by Ian Cutress on October 3, 2013 10:05 AM ESTCivilization V
A game that has plagued my testing over the past twelve months is Civilization V. Being on the older 12.3 Catalyst drivers were somewhat of a nightmare, giving no scaling, and as a result I dropped it from my test suite after only a couple of reviews. With the later drivers used for this review, the situation has improved but only slightly, as you will see below. Civilization V seems to run into a scaling bottleneck very early on, and any additional GPU allocation only causes worse performance.
Our Civilization V testing uses Ryan’s GPU benchmark test all wrapped up in a neat batch file. We test at 1440p, and report the average frame rate of a 5 minute test.
One 7970
Civ5 seems to love IPC, with our Haswell and Ivy-E CPUs all near the top. All our PCIe 3.0 combinations hit 80 FPS or above.
Two 7970s
On multiple AMD GPUs the PCIe 3.0 combiantions get the biggest boost, along with anything using a PLX or NF200 chip to boost lane allocations. There seems to be a barrier around 100-108 FPS that only Haswell and Ivy Bridge CPUs are moving over, except the one 990X result. The i7-4960X takes top spot, and the i7-920 is 45 FPS behind - almost 1/3. The i5-4430 is lower than expected, showing little scaling after the first GPU.
Three 7970s
Civ5 has terrible scaling behond one GPU let alone two, meaning most of our tri-GPU results are similar to dual GPU. Again, anything purely PCIe 3.0 seems to get the biggest boost, with the 4670K still fighting alongside the 4770K.
One 580
For a single GTX 580 the top spots above 80 FPS are all on the side of Sandy Bridge and above, with Nehalem scoring below this marker. It seems that dual core CPUs take a bashing, suggesting a quad core minimum.
Two 580s
More NVIDIA GPUs for Civ5 means more cores and more lanes where possible, with the i7-4960X taking the top spot. This is almost 40 FPS higher than the i5-4430 and the Nehalem CPUs. The 4670K doesn't miss a beat against the i7-4770K.
Civilization V Conclusion
We see some of our biggest variations in CPU performance in Civilization V, where it is clear that a modern Intel processor (Ivy/Haswell), at least quad core, is needed to get the job done for the higher frame rates. Arguably any high-end AMD processor will perform >60 FPS in our testing here as well, perhaps making the point moot. For single CPU, the i5-4430 performs well in Civ5, though in dual GPU the i5-4670K might be a better investment.

It doesn't, because it doesn't exactly capture the dynamics of displaying several player models at once. It does a decent job at displaying several preprogrammed models at once.The FF benchmarks have been a fairly low estimation of actual game performance when it comes to more demanding instances of raids and large crowds. With that said, they do better than most other canned benchmarks for determining the performance of a machine. Given it's consistent testing environment, I guess it wouldn't hurt to use it as a go-to benchmark.

But where is the Civilization V end-of-turn benchmark? I don't care about the frame rates, I care about the times I'm staring at the screen waiting for the game to finish its calculations!defiler99 - Thursday, October 10, 2013 - link
I don't normally comment (as the reviews are generally excellent), but I was actually shocked to see the choice of graphics card(s) for this roundup. Nobody buying a gaming CPU is going to have stuff that slow, right? So many of the tests result in framerates under 60fps, etc.DPOverLord - Thursday, October 10, 2013 - link
Be great to see this with the new 4930K, Titan @ 1600pdennphill - Thursday, October 10, 2013 - link
Learn to write in the English language - or at least use the grammar checker. I wince reading this article. (But thanks for the effort. Content is OK)Hrel - Monday, October 14, 2013 - link
I'm finally in the process of building a new desktop, mini-ITX. Gonna use a 4570S CPU. Primary duties will be media streaming but I'll game on it too. The computer it's replacing? 650i SLI chipset based computer running an E8400 Core 2 duo. I can still max out Mass Effect games with no issue. Minecraft maxes out the CPU but that's just because Java sucks. So that old 2007 era computer is still a viable gaming machine with the GTX460 in it. Talk of needing to replace a Nehalem CPU soon seems kind of absurd to me. But then again I have no interest in Far Cry or Crysis.markthema3 - Tuesday, October 15, 2013 - link
What about The Witcher 2 for a benchmark? I have yet to see anything be more intense than that game's Ubersampling option.SeriousTodd - Tuesday, October 15, 2013 - link
What are the disadvantages of buying a 4770K?Enterprise24 - Saturday, October 19, 2013 - link
Wanna see Total War Rome II in real time tactical mode (Probably the most CPU intensive game).boozzer - Thursday, October 24, 2013 - link
well damn. it seems like if I am single gpu gaming at 1080p, cpu doesn't matter much at all? a 5800k would do the job well enough.question: will aa amd 5800k bottleneck a gtx780? or a 290x? in 1080p. or it doesn't matter at all? since the resolution is so low. I am sure I am staying in 1080p for at least 5 more years. and my current pc parts are really old(c2d e8500 + 460 1gb) and thinking of upgrading. I am sure a 780 or 290x would last 5 or more years, so kinda want a matching cpu.
