GeForce 8800 GTS (G92)		135 Watts
	Difference: 30 Watts (29%)

Memory Bandwidth

The GeForce 8800 GTS (G92), in theory, should be just a bit faster than the GeForce 8800 GT 1GB overall. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) should be quite a bit (about 24%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 8000 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is a better choice, though only just barely. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 800 (8%)

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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
