GeForce GT 440 3GB		56 Watts
GeForce 8800 GTX		155 Watts
	Difference: 99 Watts (177%)

Memory Bandwidth

The GeForce 8800 GTX should in theory perform a lot faster than the GeForce GT 440 3GB overall. (explain)

GeForce 8800 GTX		86400 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 43200 (100%)

Texel Rate

The GeForce 8800 GTX should be much (about 158%) more effective at AF than the GeForce GT 440 3GB. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 22544 (158%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 440 3GB is superior to the GeForce 8800 GTX, though not by far. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 456 (3%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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