	Difference: 38 Watts (36%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G80) 320MB should be just a bit faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce 8800 GTS (G80) 320MB		63360 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 5760 (10%)

Texel Rate

The GeForce 8800 GT 1GB will be quite a bit (approximately 36%) faster with regards to anisotropic filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 8976 (36%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8800 GTS (G80) 320MB is superior to the GeForce 8800 GT 1GB, not by a very large margin though. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 660 (7%)

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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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