NVIDIA Quadro GP100 vs Quadro P6000

The NVIDIA Quadro GP100 has higher pixel fill rate due to greater number of Raster Operations Pipelines (ROPs), even though its graphics frequency is lower. Having better pixel fillrate allows the card to draw more pixels on screen and off screen, which is beneficial for some 3D effects in games, or when playing at higher display resolutions.

The Quadro P6000 GPU has more TMUs than the Quadro GP100. On top of that, its graphics frequency is higher, therefore its texture fillrate is higher. Having better maximum texture fill rate allows the graphics card to map more textures and/or use more sophisticated 3D effects for each texel, which improves games visual appearance.

Maximum Single Precision performance indicates how many single-precision floating point operations the graphics card can execute per second. This performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. Generally, the faster CUDA cores or stream processors run at, and the more cores / processors the graphics card has, the higher Single Precision performance will be. The NVIDIA Quadro P6000 is faster here. Higher single-precision performance number means the GPU 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 Quadro GP100 has a very significant advantage here.

To speed up processing, the cards store 3D scene data, textures and intermediate data, used for image generation, in on-board memory. The video memory usually has much higher bandwidth than system RAM, and more bandwidth allows the graphics unit to run at higher screen resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. The bandwidth is dependent on a few components, such as memory type, speed, and width of memory interface. Specifically, higher memory bandwidth of the NVIDIA Quadro GP100 is a result of wider memory bus.
