The latest version of synthetic benchmark in 3DMark line-up is actively using D3D11 API as well as physics test via Direct Compute technology, which is, by the way, a part of DirectX 11.
Performance (P) profile settings are used to evaluate the efficient of majority of Desktop computers with basic screen resolution of 1280×720 (720p). Tessellation detail is 5, Max Tessellation factor is 10.
Synthetic benchmark based on DirectX 11API alomst did not change the overall picture. GeForce GTX 570 with defoult clocks is quite comparable with RADEON HD 6950 2GB performance wise. The final results include a small loss in DirectCompute tests for GeForce GTX 570. However, once the card is clocked, it beats all contestants again.
Extreme profile sets the screen resolution to 1920×1080 (1080p). Graphics settings change too: test are run with x16 Anisotropic Filtering and x4 Anti Aliasing settings, Max Tessellation factor is 15 now.
Situation changes with extreme benchmark settings applied. Stock-clocked GeForce GTX 570 outdid RADEON HD 6950 2GB by a considerable 8%. Among overclocked card, RADEON HD 6970 with a small speed increase took the lead.
