GeForce 8800 GT 1GB		105 Watts
GeForce GTX 480		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

In theory, the GeForce GTX 480 should be much faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce GTX 480		177408 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 119808 (208%)

Texel Rate

The GeForce GTX 480 is a lot (more or less 25%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 8400 (25%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 480 is superior to the GeForce 8800 GT 1GB, by far. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 24000 (250%)

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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
