Performance Meets Value – Core i7 vs. Penryn vs. Phenom II
S.T.A.L.K.E.R., Clear Sky
Prologue: S.T.A.L.K.E.R., Clear Sky became a brand new DX10 benchmark for us when GSC Game World released a prequel story expansion to the original Shadows of Chernobyl, last year. Both games have non-linear storylines which feature role-playing game elements. In both games, the player assumes the identity of a S.T.A.L.K.E.R.; an illegal artifact scavenger in “The Zone” which encompasses about 30 square kilometers. It is the location of an alternate reality story surrounding the Chernobyl Power Plant after another (fictitious) explosion.
S.T.A.L.K.E.R., Clear Sky features “a living breathing world” with highly developed NPC creature AI. It uses the X-ray Engine – a DirectX8.1/9/DX10/10.1 Shader model 3.0 & 4.0 graphics engine featuring HDR, parallax and normal mapping, soft shadows, motion blur, weather effects and day-to-night cycles. As with other engines using deferred shading, the original DX9c X-ray Engine does not support anti-aliasing with dynamic lighting enabled, although the DX10 version does.
We are using the stand-alone “official” benchmark by Clear Sky’s creators. Clear Sky is top-notch and worthy to be S.T.A.L.K.E.R’s successor with even more awesome DX10 effects which help to create and enhance their game’s already incredible atmosphere. Unfortunately, DX10 comes with steep hardware requirements and this new game really needs multi-GPU to run at its maximum settings. We picked the most stressful test out of the four, “Sun shafts”. It brings the heaviest penalty due to its extreme use of shaders to create DX10/DX10.1 effects. We ran this benchmark fully maxed out in DX10.0 with “ultra” settings plus 4xAA, but did not apply edge-detect MSAA which chokes performance even further.
We present S.T.A.L.K.E.R., Clear Sky DX10 benchmark “Sun shafts” at 1920×1200:
Now at 1680×1050:
This time, with our HD 4870-X2 or our GTX 280 we do not see much variance in frame rates anywhere. Less than two or three frames per second separate the fastest CPU from the slowest one – and that is generally at the maximum which makes zero difference to the playing experience. Practically there is no real difference gained with any CPU; the video card will make the most difference with Clear Sky’s performance.
Are we starting to see a pattern?
very thorough and informative, i glanced over it but i will read it later. looking at the graphs and conclusion good stuff look forward to seeing more cpu’s put to the test.
The almost constant flat-lining from the different processors yet again proves the GPU is by far the most important factor for gaming.
I agree that the cpu bottlenecks that people talk about so much are very very overblown.
But they still do matter in gaming. Of course not as much as a video card but they are still very important.
The games you tested are older games. They don’t take use of more than 2 cores decently.
Just about every recent release however is coded to use more than 4 cores. And there are some very LARGE performance differences even when playing at good resolutions and high settings. Recent Source games, Capcom games will make use of more cores because the engines they use have been updated for multi core support.
I’m going to show a couple of examples.
Reisdent Evil 5

A 2.4GHz Q6600 beats a 3.0GHz e8400
The 3.1GHz Phenom II X2 550 gets 54.2FPS and the Phenom II X4 945 @ 3.0GHz gets 81.5
The settings were at 1680 x 1050 all settings max.

All of these games has been tested with high settings at decent and very common gamer resolutions like 1680 x 1050.
There are lots and lots more but I don’t feel like posting any more links. I think that I’m able to make show my point with these games. Just about every recent release comes with great quad core support. I’d be more surprised if a recent game didn’t come out with quad core support.
Thanks for you comments. Let’s look, one at a time at each of your examples:
RE5, they do not test with AA or AF and only at 16×10. Of course, the bottleneck is shifted to the CPU.
Dirt 2, same issues. I test everything with 4xAA/16xAF. The author agrees with me:
” In most systems, especially with DirectX 11, the graphics card is the limiting factor. ”
Prototype. Ph II 940-X4 is barely 3 FPS behind i7. Watch that difference disappear at 19×12 and with faster clocks.
L4D. As with with all Source engine games, the practical difference is minimal. Again, they do not test with AA/AF – which is silly.
ARMA2, I also test; except that I use the highest details and with different results.
Batman AA. Here is what THG concludes:
“We now see that a dual-core Phenom II CPU at 2.5 GHz can handle a minimum frame rate of over 40 FPS. This means that even a sub-$100 CPU should be able to deliver excellent performance with Batman: Arkham Asylum.” Dropping the CPU core speed to 2.0 GHz; why don’t they go to 1 GHz to make a point?
GTA4. They test at 10×12. Ridiculous. Enough said.
You may like Part 2 of my review. It is greatly expanded to include the same 3 CPUs and also now with Ph II 550 X2 and Ph II 955 X4. I am also now testing with HD 4870-X2 and HD 4870-X3 TriFire to up the graphics ante.
It takes me a few weeks to run over 1,000 benchmarks on 17 games for 5 CPUs at three clock speeds and at two resolutions for my upcoming article. –Look for it December 21st.
My test games are certainly not old. However, look for me to add Dragon’s Age: Origins, Left4Dead, Wolfenstein, Borderlands, Dirt2, and CoD MW2 in the coming weeks.
Quad core is becoming more useful for brand new games. Eventually it will be necessary. But not yet.
