ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. It is measured in millions of texels applied per second. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). This 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 texture map elements (texels) that can be processed in one second. It especially helps with AA, High Dynamic Range and high resolutions.

The better the bandwidth is, the faster the card will be in general. If the card has DDR memory, it should be multiplied by 2 once again. It is worked out by multiplying the card's bus width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second.
