Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
GeForce GTX 570		219 Watts
	Difference: 174 Watts (387%)

Memory Bandwidth

In theory, the GeForce GTX 570 should perform quite a bit faster than the GeForce 8500 GT overall. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 139200 (1088%)

Texel Rate

The GeForce GTX 570 will be a lot (approximately 1120%) better at texture filtering than the GeForce 8500 GT. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 40320 (1120%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 570 is superior to the GeForce 8500 GT, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 27480 (1527%)

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 data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
