Video Gaming Test
Benchmark Reviews continually evaluates the various tests and benchmarks we use, and we have switched from Ubisoft's Far Cry 2 benchmark to CAPCOM's Street Fighter IV benchmark. Street Fighter IV uses a new, built-from-scratch graphics engine that enables CAPCOM to tune the visuals and performance to fit the needs of the game, as well as run well on lower-end hardware. Although the engine is based on DX9 capabilities, it does add soft shadows, High Dynamic Range lighting, depth of field effects, and motion blur to enhance the game experience.
The game is multithreaded, with rendering, audio, and file I/O all running in different threads. The development team has also worked to maintain a relatively constant CPU load in all parts of the game so that on-screen performance does not change dramatically in different game scenarios.
I ran the Street Fighter IV benchmark at low-resolution, low settings as well as high-resolution, high settings. Low-resolution settings were 1024x768, no AA, with all other settings set to minimum; high resolution tests were run at 1920x1280 with 8xAA and all other settings maxed out. Low-resolution gaming tests make the video card less of a factor since any high-end video card like the NVIDIA GTX280 used in these tests can easily handle them; differences here are more biased towards processor horsepower. The Intel Core i5-750 brings up the rear here, but the real surprises are that the 2.66GHz, 4-core i7-930 performs identically to the 3.33GHz, 6-core 980x, and that every AMD CPU beats every Intel CPU. Yep, even the AMD 965 Black Edition trounces the Core i7-980x with a score almost 16% higher. Although the game is multithreaded, the low-resolution performance results seem to favor clock speed over the number of cores (although every processor here is at least a quad-core, so perhaps more differences would be seen comparing a dual-core to a quad-core CPU).
In the high-resolution tests, as expected, the results are all similar, since the graphics card becomes the deciding factor. All the AMD processors turn in more or less identical results, with the Intel processors very close, but showing inverse performance, i.e. the Core i5-750 is best, then the Core i7-930, then the Core i7-980x. At Benchmark Reviews, we strive to keep this point in front of our readers: your processor makes relatively little difference in your gaming experience.
