The latest version of Futuremark's synthetic 3D gaming benchmark, 3DMark11, is specifically bound to Windows Vista and WIndows 7-based systems due to its DirectX 11 requirement, which isn't available on previous versions of Windows. 3DMark11 isn't simply a port of 3DMark Vantage to DirectX 11, though. With this latest version of the benchmark, Futuremark has incorporated four new graphics tests, a physics tests, and a new combined test. We tested the graphics cards here with 3DMark11's Extreme preset option, which uses a resolution of 1920x1080 with 4x anti-aliasing and 16x anisotropic filtering. |
Once again, the dual-GPU powered cards are able to maintain significant leads, which is to be expected of course. Beyond that, the Radeon HD 7970 proved to be the fastest single-GPU powered card in 3DMark 11. In this test, the Radeon HD 7970 was about 47% faster than AMD's previous flagship single-GPU, the Radeon HD 6970, and approximately 31% faster than the GeForce GTX 580. The factory OC'd 3GB GeForce GTX 580 cut the Radeon's lead down to roughly 18.9% here but it's still an impressive performance for ATI's newcomer.
