Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
GeForce GTX 570		219 Watts
	Difference: 133 Watts (155%)

Memory Bandwidth

Theoretically, the GeForce GTX 570 should be quite a bit faster than the Radeon HD 6750 1GB in general. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 88000 (138%)

Texel Rate

The GeForce GTX 570 should be much (more or less 68%) more effective at texture filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 17820 (68%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 570 is a better choice, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 17680 (152%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed per second. This number 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
