EVGA GeForce GT 710 2GB GDDR5 vs NVIDIA GeForce GT 620

The maximum pixel fillrate is dependent on graphics clock rate and the number of ROPs (Raster Operations Pipelines). The EVGA GeForce GT 710 2GB GDDR5 has a massive lead in this area, as it has twice as many Raster Operations Pipelines (ROPs), and operates at higher frequency. Better pixel fill rate allows more pixels to be drawn on screen per second, which results in increased GPU performance, unless there are bottlenecks somewhere else.

In modern games, pixel fillrate is not as important as texture fill rate. This parameter is calculated as the number of TMUs, multiplied by graphics clock. Since both GPUs have the same number of Texture Mapping Units (TMUs) and the GeForce GT 710 2GB GDDR5 card runs at higher frequency, its texture fillrate is higher. Better maximum texture fill rate allows the graphics card to utilize more complex 3D effects and/or map more textures to each texel, which improves visual appearance of games and generated images.

Maximum Single Precision performance indicates how fast the graphics card is at executing applications, that make an extensive use of single-precision floating point numbers. The performance is measured in GFLOPS, or Giga (billions of) Floating Point Operations Per Second. All single-precision calculations are performed by stream processors or CUDA cores, as such the more cores / processors the graphics card has the better. Performance also depends on the processor clock speed. The EVGA GeForce GT 710 2GB GDDR5 GPU is faster here. Higher single-precision performance number means the graphics unit 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.

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 card to run at higher display resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. Memory type, speed, and width of memory interface all affect the bandwidth value. Specifically, the GeForce GT 710 2GB GDDR5 offers higher clocked memory of better kind. As a consequence, it has higher memory bandwidth.
