Video Gaming Test
UbiSoft's Far Cry 2 game features a vast African landscape which you can wander freely about, choosing your own path through the game without being constrained by the developer's idea of how it should progress. The lack of distinct "levels" within the game encourages the player to explore multiple paths and goals. The "Dunia" game engine developed by UbiSoft's Montreal development team purportedly makes good use of multi-core processors to leverge its real-time lighting effects and advanced vegetation rendering.
Far Cry 2 has a handy built-in benchmarch that allows you to define a set of parameters and run one of several demos automatically using different settings. For these tests I chose the "Ranch Small" demo and ran it at 1280 x 1024 with minimal settings and no anti-aliasing, and at 1920 x 1280 with all settings maxed out and 8x anti-aliasing. All tests were run in DirectX 10.
Low-resolution gaming tests make the video card less of a factor since any high-end video card like the Radeon 5870 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, with only about half the performance of its i7-860 and i7-930 brethren. For the minimum frame rate, the i7-980X adds 19% to the performance of the next-closest i7-860, but that's exactly the difference in clock speeds between the two processors, so it seems that the Dunia engine doesn't scale well (or at all) beyond four cores. The differences between the two are less dramatic in the average and maximum Intel frame rates, shrinking to a little over 9%. As can be seen from the AMD results, this game favors Intel processors pretty heavily, at least at low resolutions: the only time they're in the lead is in the minimum frame rate, and then they only outpace the underdog i5-750.
At a more reasonable resolution, the minimum and average frame rates are virtually identical across all the CPUs being tested, indicating that the Radeon 5870 video card is now the limiting factor. Only in the maximum frame rates is there any difference, and although the Intel family wins again, even the slowest CPU (the stock-clocked 1075T) returns frame rates that are far beyond what's needed to be very playable. The differences in the maximum frame rate inside each processor family scale almost linearly with clock speed, with the hexacore processors showing no advantage over the quad-cores.
