GeForce GTX 560 vs Radeon HD 6950
Intro
The GeForce GTX 560 features a core clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon HD 6950, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

Why you should believe none of what you hear and only half of what you see: http://www.tomshardware.com/forum/307584-33-5870-6950-dont
Apparently, a Tom's H/W "Guru" predicted the 560 would be a superior card .. how'd that turn out??? What a load of fooey. People, do your own research & gather as much background on cards before committing to any particular model or brand.
