Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti 448		210 Watts
Radeon HD 5970		294 Watts
	Difference: 84 Watts (40%)

Memory Bandwidth

In theory, the Radeon HD 5970 should be 78% quicker than the GeForce GTX 560 Ti 448 in general, because of its greater bandwidth. (explain)

Radeon HD 5970		256000 MB/sec
GeForce GTX 560 Ti 448		144000 MB/sec
	Difference: 112000 (78%)

Texel Rate

The Radeon HD 5970 should be quite a bit (approximately 466%) faster with regards to texture filtering than the GeForce GTX 560 Ti 448. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 191008 (466%)

Pixel Rate

The Radeon HD 5970 should be much (approximately 217%) better at full screen anti-aliasing than the GeForce GTX 560 Ti 448, and should be able to handle higher screen resolutions better. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 560 Ti 448		29280 Mpixels/sec
	Difference: 63520 (217%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
