NVIDIA Tesla C2075 vs Tesla K10 theoretical performance

Each graphics unit has several vital theoretical parameters that affect real-world game, 3D graphics and compute performance. These are texture fillrate, pixel fillrate, memory bandwidth, along with single- and double-precision performance. Below you will find why they are important, and which card has better characteristics.

Pixel fill rate (gigapixels/s) 60 48 36 24 12 0   27.6   47.7     Higher is better	The Tesla K10 card has more Raster Operations Pipelines (ROPs) than the NVIDIA Tesla C2075. On top of that, its graphics clock rate is higher, therefore its pixel fillrate is substantially higher. Better maximum pixel fill rate means that the GPU can draw more pixels on and off screen each second, increasing overall performance, unless the card is limited by something else, such as texture fillrate, memory bandwidth or CPU speed.

Texture fill rate (gigatexels/s) 300 240 180 120 60 0   32.2   191     Higher is better	Because the NVIDIA Tesla K10 graphics unit has many more TMUs (Texture Mapping Units) and higher graphics frequency, its texture fillrate is considerably higher. Better texture fill rate means that the GPU can use more complex 3D effects and/or apply more textures to each textured picture element, which improves games visual appearance.
Single Precision performance(GFLOPS) 6000 4800 3600 2400 1200 0   1030   4577     Higher is better	Maximum Single Precision performance indicates how fast the graphics card is at executing 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 more stream processors or CUDA cores the graphics card has, and the the faster they run at, the higher Single Precision performance will be. The NVIDIA Tesla K10 GPU has an upper hand 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.
Double Precision performance(GFLOPS) 600 480 360 240 120 0   515   191     Higher is better	Maximum Double Precision performance is similar to the Single Precision performance, except that it applies to double-precision (64-bit) floating point operations. Since games do not use double-precision arithmetics, this characteristic is unimportant to games performance. The Tesla C2075 is faster when processing 64-bit floating-point numbers.

Memory bandwidth (GB/s) 400 320 240 160 80 0   144   320     Higher is better	To speed up processing, the GPUs 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 GPU to run at higher display resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. The bandwidth depends on a few components, such as memory type, speed, and memory interface width. Specifically, higher memory bandwidth of the NVIDIA Tesla K10 is due to higher memory clock.
