A synthetic test giving the performance picture of your graphic card using DirectX 10 API. As physics test are supported here by NVIDIA PhysX and not available for ATI|AMD graphic cards, the benchmark setting had PPU disabled thus putting card in to equal test conditions.
Graphics benchmarks of Performance profile are run with 1280х1024 resolution suitable for majority of computer systems nowadays.
For High profile test 1680×1050 screen resolution is set, x8 Anisotropic Filtering and x2 Anti Aliasing, texture are harder to render too.
The heaviest test with resolution of 1920×1200, x16 Anisotropic Filtering and x4 Anti Aliasing settings resembles Extreme profile.
Unlocked variant of Radeon HD 6950 2GB shows performance advantage of 13-17%. The difference between cards with same clocks reaches 3% in Performance profile tests, while heavier benchmark settings show that unlocked card is faster that overclocked one by 6%.
