PC Gaming: I Need Your Input For A Project!

post #1 of 29
Thread Starter 
Hello PC Gamer section!

I've come to you to ask for your assistance in an upcoming project.

There have been MANY MANY threads lately discussing bottlenecking, both CPU and GPU, and I thought I would put a good deal of time into a project analyzing the outcomes of different CPU core/thread configurations, CPU speeds, and number of GPU's for the benefit and understanding of the OCN community at large.

I will take my CPU, an i7 930, and configure it in the following manner:

2 cores / 2 threads
2 cores / 4 threads
4 cores / 4 threads
4 cores / 8 threads

I would prefer to perform tests on different processors but unfortunately all my older systems have been torn down and parted out.

Each of these cpu configurations will be clocked at the following speeds:

2.8 GHz
3.3 GHz
3.7 GHz
4.1 GHz

Each cpu/speed combination will then be combined with one, two and finally three EVGA GTX 470 GPU's @ 750/1500/1950.

I will then take each cpu/speed/gpu combination and run it through the following benchmarks at three different resoltions, 1280 x 1024, 1650x1080, 1920x1200:
  • 3dMark Vantage Benchmark
  • 3dMark 11 Benchmark
  • Aliens Vs Predator Benchmark Tool
  • Cryostasis Benchmark Tool
  • Crysis I Benchmark Tool
  • Far Cry II Benchmark Tool
  • F.E.A.R. II Benchmark Tool
  • H.A.W.X II Benchmark Tool
  • Just Cause II Benchmark Tool
  • Mafia II Benchmark Tool
  • Left 4 Dead II Benchmark
  • Lost Planet II Benchmark Tool
  • Metro 2033 Benchmark Tool
  • Resident Evil V: Benchmark Tool
  • Stalker: Clear Sky Benchmark Tool
  • Stalker: Shadow of Chernobyl Tool
  • Stone Giant Benchmark
  • Supreme Commander II Benchmark
  • Unigine Heaven 2.5 Benchmark
  • X3: Terran Conflict Benchmark Tool

Each benchmark will be performed with two different settings profiles, "Performance" and "Extreme". Within the bounds of this analysis Performance will generally refer to the halfway point of any given value offered by a benchmark while Extreme will always be the maximum.

I will record the minimum/maximum/average FPS across each combination and incorporate that data into charts and graphs showing where and if certain games / benchmarks benefit from increased clock speeds with certain numbers of GPUs.

I will also be recording the GPU load and CPU core/thread load for each test and be posting that information as well just to show how each game functions and to help explain results.

Now the reason I've come to you is that this analysis is primarily intended for you, the gamers. Is there a benchmark not on this list you'd like to see done or something else you'd like to see done within the bounds of this analysis?

If there's a benchmark or game you'd like to see please post a link or just ask for it and I'll see if I have it in my Steam library.

Thanks for any suggestions and your time in reading this!

great idea, and bravo for the effort

how bout a GTA IV benchmark? That one always raises the "bottleneck!!1!" argument

That's one that's been requested quite a bit in my discussions with others on this project. Unfortunately I don't have it on Steam yet but once it's on sale again(summer sales probably) I'll pick it up and run it through the tests!

I think you should also run Unreal Tournament and give the marks for that aswell ;D

but seriously, It's a pretty awesome list you have put up for what you're going to do. Very time consuming but would provide a lot of unbiased facts.

D'oh! GTA IV was in the sales last week

one of the biggest issues with CPU bottleneck isn't actually the power of the processor itself, but the infrastructure they are based on.

If you do all the experiments with the same processor, just with different core configurations, you will still have the same PCIe configurations, northbridge, southbridge, etc...

Yeah I thought of this when setting up the parameters of the test. Unfortunately I don't have any other equipment perform the tests with. Given this limitation would you prefer to just see a 4/4 and 4/8 i7 930 configuration?

I think the 2 cores 4 threads would be interesting, just to see if the hyperthreaded Sandy i3s would be enough for a super low profile/budget gaming build. I also would like to see GTA IV and would looooove to see Starcraft 2, that game is what really made me spend what I did on my CPU, because from what I have seen even thought it's "just dual core optimized" nothing can push it like a Sandy.

Settle down peasant! I've got five, count em, FIVE days to do all this, get the data I need and get it over to my laptop where I can work on the actual charts/graphs/analyses. As if I'm going to miss the CC.
