![]() Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. It is measured in millions of texels in one second. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The better the bandwidth is, the faster the card will be in general. If the card has DDR RAM, it must be multiplied by 2 once again. It's calculated by multiplying the 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 over the external memory interface in a second. ![]()
