Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 512MB		86 Watts
GeForce GTX 580		244 Watts
	Difference: 158 Watts (184%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 will be 161% faster than the Radeon HD 5750 512MB in general, due to its higher bandwidth. (explain)

GeForce GTX 580		192384 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 118784 (161%)

Texel Rate

The GeForce GTX 580 should be much (more or less 96%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 24208 (96%)

Pixel Rate

The GeForce GTX 580 will be quite a bit (more or less 231%) more effective at AA than the Radeon HD 5750 512MB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 25856 (231%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
