The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. Passmark, SPECviewperf 12, 3Dmark and other.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. GPU Comparison Specs & Benchmarks NVIDIA GeForce GTX 860M vs NVIDIA GeForce GTX 660. It is measured in millions of texels per second. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. It especially helps with AA, HDR and higher screen resolutions. The higher the card's memory bandwidth, the faster the card will be in general. In the case of DDR type RAM, the result should be multiplied by 2 once again. It is calculated by multiplying the bus width by its memory speed. Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface within a second.
