Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce 8800 GTX		155 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

In theory, the GeForce 8800 GTX should be 39% quicker than the GeForce 8800 GTS (G92) in general, because of its higher bandwidth. (explain)

GeForce 8800 GTX		86400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 24320 (39%)

Texel Rate

The GeForce 8800 GTS (G92) is just a bit (approximately 13%) better at AF than the GeForce 8800 GTX. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 4800 (13%)

Pixel Rate

The GeForce 8800 GTX will be much (approximately 33%) better at FSAA than the GeForce 8800 GTS (G92), and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 3400 (33%)

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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
