ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second.

It is measured in millions of texels per second. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. It especially helps with AA, High Dynamic Range and high resolutions. The higher the card's memory bandwidth, the faster the card will be in general. In the case of DDR type RAM, the result should be multiplied by 2 once again.

It is calculated by multiplying the bus width by the speed of its memory. Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second.
