Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon HD 5970		294 Watts
	Difference: 234 Watts (390%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be 196% faster than the GeForce GTX 750 Ti in general, because of its higher data rate. (explain)

Radeon HD 5970		256000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 169600 (196%)

Texel Rate

The Radeon HD 5970 will be a lot (more or less 469%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 191200 (469%)

Pixel Rate

The Radeon HD 5970 is quite a bit (approximately 469%) faster with regards to FSAA than the GeForce GTX 750 Ti, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 76480 (469%)

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 megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
