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

Texel Rate

The GeForce 8800 GS should be a lot (about 85%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 12144 (85%)

Pixel Rate

The GeForce GT 440 1.5GB will be much (more or less 116%) better at full screen anti-aliasing than the GeForce 8800 GS, and will be able to handle higher resolutions more effectively. (explain)

GeForce GT 440 1.5GB		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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
