The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied per second. PE alienware 13 R1 i5 4200U gtx 860m 2gb W 4/0 SaltiMate PE-JIGGER ULT 4 1200m SP.
The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This is calculated by multiplying the total texture units of the card by the core speed of the chip. Nvidia’s 3080 GPU offers once in a decade price/performance improvements: a 3080 offers 50 more effective speed than a 2080 at the same MSRP.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The better the card's memory bandwidth, the faster the card will be in general. If the card has DDR type memory, the result should be multiplied by 2 once again. The number is calculated by multiplying the card's bus width by its memory speed.
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second.
