GeForce 8800 GS		38400 MB/sec
	Difference: 4800 (13%)

Texel Rate

The GeForce 8800 GS will be a lot (about 85%) more effective at AF than the GeForce GT 440 3GB. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 12144 (85%)

Pixel Rate

The GeForce GT 440 3GB is a lot (more or less 116%) faster with regards to AA than the GeForce 8800 GS, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 7656 (116%)

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 data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core clock 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 card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
