Call of Duty 4
Call of Duty 4 is a DirectX 9 game implementing high-dynamic range (HDR) and its own physics engine. We ran this game at 1920×1200 with all image quality settings at their minimum values (no anti-aliasing and no anisotropic filtering). We used the game internal benchmarking feature, running a demo provided by nVidia called wetwork. We are putting this demo for downloading here if you want to run your own benchmarking. The game was updated to version 1.7. We ran this test five times, discarding the lowest and the highest scores. The results below are an arithmetic average of the three remaining values, given in frames per second (FPS).
On Call of Duty 4, the Core i7-2600K (3.4 GHz) was 9% faster than the Core i7-875K (2.93 GHz) and 12% faster than the Phenom II X6 1100T (3.3 GHz). It is important to understand that we lowered the image quality settings to their minimum values in order to measure the CPU performance; by increasing image quality settings you start to measure the performance of the video card, not the CPU, and under this scenario all CPUs will get similar performance on this game. Since users buying a high-end CPU to play games will probably buy a high-end video card and max out image quality settings, the gaming performance will be set by the video card, and not by the CPU.
