GeForce 8800 GS		38400 MB/sec
	Difference: 95520 (249%)

Texel Rate

The GeForce GTX 470 is quite a bit (about 29%) more effective at AF than the GeForce 8800 GS. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 7592 (29%)

Pixel Rate

The GeForce GTX 470 should be quite a bit (about 268%) faster with regards to AA than the GeForce 8800 GS, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 17680 (268%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
