![]() ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). ![]() The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. It is measured in millions of texels processed in a second. ![]() The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The higher the memory bandwidth, the faster the card will be in general. If it uses DDR RAM, it should be multiplied by 2 again. The number is worked out by multiplying the card's interface width by its memory clock speed. Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second.
