GeForce GTX 560 Ti 448 vs Radeon HD 5970

Intro

Compare all of that to the Radeon HD 5970, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this model. It features 1600 SPUs as well as 160 TAUs and 64 ROPs.

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 560 Ti 448, by far. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of 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.
