	Difference: 30 Watts (29%)

Memory Bandwidth

In theory, the GeForce 8800 GTS (G92) will be 8% quicker than the GeForce 8800 GT 512MB in general, due to its greater data rate. (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) is quite a bit (approximately 24%) more effective at AF 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) is a little bit (about 8%) more effective at FSAA than the GeForce 8800 GT 512MB, and also will be able to handle higher screen resolutions better. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
