ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The number is calculated by multiplying the number of ROPs by the the core speed of the card. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels in a second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. It especially helps with anti-aliasing, HDR and high resolutions. The higher the bandwidth is, the better the card will be in general. If it uses DDR RAM, the result should be multiplied by 2 once again. It's worked out by multiplying the card's interface width by its memory speed. Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second.
