ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied in one second. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). This number is worked out by multiplying the total texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second.

It especially helps with AA, HDR and higher screen resolutions. The better the bandwidth is, the better the card will be in general. If the card has DDR memory, the result should be multiplied by 2 once again. It is calculated by multiplying the card's interface width by its memory clock speed. Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second.
