GIGABYTE GeForce GT610 2GB vs NVIDIA GeForce GT 610

Pixel fillrate number determines how many pixels a graphics unit can draw on screen and off screen. The higher this number, the higher display resolution and frame rate the graphics card can support. There are two factors that affect the maximum pixel fillrate. These are graphics clock rate and the number of ROPs (Raster Operations Pipelines). Since both characteristics are identical between GPUs, their pixel fillrate is also equal.

There are two factors that influence the maximum theoretical texture fillrate. They are the number of TMUs and graphics frequency. Because both models have the same number of Texture Mapping Units and the same graphics frequency, their texture fillrate is identical.

Single Precision performance shows how fast the graphics card is at executing programs, that process only single-precision floating point data. The performance is measured in GFLOPS, which stands for Giga (billions of) Floating Point Operations Per Second. As a rule, the faster stream processors or CUDA cores operate at, and the more cores / processors the graphics card has, the better Single Precision performance will be. These two graphics cards have the same maximum single-precision performance.

Memory bandwidth parameter specifies how much memory (in Gigabytes) the GPU can read from or write to dedicated memory per second. GPUs with higher memory bandwidth have better performance at high display resolutions, or when using large and detailed textures, and/or utilizing complex 3D effects and filters, like anti-aliasing. The bandwidth depends on a few components, such as memory type, speed, and memory interface width. Specifically, the GeForce GT 610 offers higher memory clock. As such, it has more memory bandwidth.
