GPU Number Crunching


SiSoft SANDRA is an information and diagnostic utility. It provides useful information about your hardware, software, and other installed devices. SANDRA gives you the ability to draw comparisons at both a high and low level. The SiSoftware GPGPU processing benchmark performs single- and double-precision floating point arithmetic on the GPU and the results are reported in pixels/s, i.e. how many pixels can be computed in 1 second.

The graphs above show compute shader processing performance along with the memory bandwidth performance associated with it. Compute shader is a new programmable shader stage introduced with DirectX 11 that expands Direct3D beyond just graphics programming. Since both NVIDIA and ATI camps support it, we ran the test on every videocard we used in this article.

Not surprisingly, the V7900 trails the V7800 in GPGPU processing performance due to having fewer stream processors available. But it stays on par during the memory bandwidth test at 22 GB/s. Additionally, the V5900 performs well, leading the V4800 by 91% during the first test.
