GeForce GTX 570 vs Radeon HD 5870
Intro
The GeForce GTX 570 features a clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 40 ROPs.Compare that to the Radeon HD 5870, which features a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 1600(320x5) SPUs, 80 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
