GeForce 8800 GT 512MB		105 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 30 Watts (29%)

Memory Bandwidth

Theoretically, the GeForce 8800 GTS (G92) should perform just a bit faster than the GeForce 8800 GT 512MB in general. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) should be quite a bit (about 24%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 8000 (24%)

Pixel Rate

The GeForce 8800 GTS (G92) will be a little bit (more or less 8%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 512MB, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce 8800 GT 512MB		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: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, HDR 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 amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
