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