GeForce GTX 570 vs Radeon HD 6950

Intro

The GeForce GTX 570 has a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 memory runs at 950 MHz through a 320-bit bus. It also features 480 SPUs, 60 TAUs, and 40 ROPs.

Compare those specs to the Radeon HD 6950, which comes with GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

This is absolute BS .. the forum admin's cherry pick a few games and declare a winner based on p!$$ weak, anecdotal and inconclusive tests. The GTX 570 will be a better card at higher resolutions, but the cards are likely very similar in 3D, gpu-intensive performance tasks (give or take a few fps in favor of the 570), otherwise.
