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.
The benchmark responded to increased memory clocks quite well as well as to GPU clocks. When having overclocked memory only, from 950 MHz to 1235 MHz, this has resulted in additional 1050 points for graphics benchmarks. It is not so bad, though the gain in percents is rather small.
The heaviest test with resolution of 1920×1200, x16 Anisotropic Filtering and x4 Anti Aliasing settings resembles Extreme profile:
Same story here, the benchmark reacts well to memory and GPU overclocking. As for memory only overclocking, to 1235 MHz, it brought 705 points plus, which can be considered as really good result.
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.
Memory overclock, from 950 MHz to 1235 MHz added 291 points. Generally, nothing to be amused of — memory and graphics processors overclock provide a little enchantment.
Extreme profile sets the screen resolution to1920x1080 (1080p). Graphics settings change too: test are run with x16 Anisotropic Filtering and x4 Anti Aliasing settings, Max Tessellation factor is 15 now.
The picture has not change much, a small performance boost generated by higher clocked GPU and memory.
Unigine Heaven 2.1
Unigine Heaven 2.1 becnmark demonstration the possibilities of Unigine game engine. This benchmark widely uses all DirectX features and provides with quite high result repeatability.

And here is the first application where memory clock is a bottleneck for even overclocked GPU — test results with 950/1050 MHz settings took lower place than the one clocked at 900/1235 MHz. Higher memory clocks, 1250 MHz, shows true power of graphics processor overclocked to 950 MHZ. This makes it obvious — GPU overclocking is not legit without memory overlooking.
