![]() Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. It is measured in millions of texels processed in one second. ![]() The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. It especially helps with anti-aliasing, HDR and high resolutions. ![]() The higher the memory bandwidth, the better the card will be in general. If it uses DDR type memory, it should be multiplied by 2 once again. ![]() The number is worked out by multiplying the bus width by its memory speed. Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. ![]()
