ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The figure is calculated by multiplying the number of ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. It is measured in millions of texels applied 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 of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The higher the card's memory bandwidth, the better the card will be in general. In the case of DDR memory, it must be multiplied by 2 again. The number is calculated by multiplying the interface width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second.
