Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

Comments
One Response to “GeForce GTX 980 vs Radeon R9 390 8G”OK i did some checking on YouTube for videos showing the actual performance of each of these two graphics cards.An the information on this base is wrong.The Texture Fillrate of the GTX 980 an R9 390 are the same.at 160 to 162 in favor of Nvidia.But the actual Pixel rate is completely wrong.The Pixel loads for the GTX 980 is only 36.1 on one GPU-z i found an one video live of it at exactlly 40.5 on an overclocking video.Where the AMD GPixel Fillrate was 64.0.Thats double the performance!An by no means does the GTX ram reatch 7000Mhz.That is a balled face lie! it is 1753MHz.An not 7000Mhz.The AMD is 6000MHz.So some one fix that.
