Metro 2033

This game runs without multisampling antialiasing because it worsens the quality of textures and lowers the frame rate.

Contrary to our expectations, the AMD products prove to depend more on the CPU at 2560x1600. At the lower resolutions the difference between the two CPUs from Intel is negligible.

The same is true for the Nvidia GeForce series, the GeForce GTX 400 cards being somewhat slower with the top-end CPU at high resolutions. This may be a negative effect of Hyper-Threading technology which is enabled in the Intel Core i7-975 EE by default.

S.T.A.L.K.E.R.: Call of Pripyat

We use the game’s DirectX 10.1 and DirectX 11 modes for graphics cards that support them.

The Radeon HD 5850 is the least CPU-dependent product from AMD here. When installed into the LGA1156 platform, it slowed down by 0.5 to 21% whereas the other Radeons could be up to 30-35% slower with the Core i5-750, especially at the lowest resolution.

The Nvidia cards are good in this test. The GeForce GTX 480 slows down by 17% only when moving to the slower platform. The difference is even smaller than 10% at high resolutions. The less advanced graphics cards are even more indifferent to the CPU. There is one important nuance with graphics cards from both developers: they deliver a higher bottom speed on the LGA1366 platform with Core i7-975 processor and you should take this into account if you want to play at high resolutions.

Wolfenstein

This game is tested in multiplayer mode that uses the OpenGL API. The integrated benchmark does not report the bottom frame rate.

This game is rather simple in terms of visuals and 3D technologies. The CPU doesn’t influence the frame rate much as we benchmark the multiplayer mode. The difference between the two Intel platforms is about 10%, reaching 12-15% in a few individual cases like when the top-end cards from AMD and Nvidia perform at low resolutions. At 2560x1600 the difference between the expensive and affordable CPUs is negligible.
