NVIDIA Quadro 6000 vs Tesla C2075

Since both graphics units have the same number of ROPs and the Tesla C2075 GPU has higher operating frequency, its pixel fillrate is a bit higher. Better maximum pixel fill rate allows more pixels to be drawn on screen per second, and is an indication of better card performance, unless there are bottlenecks in other areas, such as memory bandwidth or texture mapping.

In modern games, pixel fillrate is not as important as texture fill rate. This parameter is proportional to graphics clock and the number of TMUs (Texture Mapping Units). The Tesla C2075 has a no lead here, as it operates at slightly higher frequency, and both cards have the same number of TMUs. Better maximum texture fill rate means that the GPU can use more complex 3D effects and/or map more textures to each texel, which improves visual appearance of games and generated images.

Single Precision performance shows how fast the graphics card is at running programs, that process primarily single-precision floating point data. The performance is expressed in GFLOPS or billions of Floating Point Operations Per Second. Generally, the faster stream processors or CUDA cores operate at, and the more cores / processors the graphics card has, the higher Single Precision performance will be. The NVIDIA Tesla C2075 is insignificantly faster here. Higher single-precision performance number means the graphics card will perform better in general computing applications. Since CUDA cores or stream processors are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

Maximum Double Precision performance is similar to the Single Precision performance, except that it applies to double-precision (64-bit) floating point operations. Games do not use double-precision arithmetics, therefore this characteristic is unimportant to their performance. The Tesla C2075 graphics card has an upper hand here.

Memory bandwidth of GPUs is identical.
