GeForce 8800 GS		105 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 55 Watts (52%)

Memory Bandwidth

The GeForce GTX 460 2GB should in theory be much faster than the GeForce 8800 GS overall. (explain)

GeForce GTX 460 2GB		115200 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 76800 (200%)

Texel Rate

The GeForce GTX 460 2GB should be much (approximately 43%) more effective at AF than the GeForce 8800 GS. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 11400 (43%)

Pixel Rate

The GeForce GTX 460 2GB is quite a bit (approximately 227%) more effective at full screen anti-aliasing than the GeForce 8800 GS, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 15000 (227%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus 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 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
