Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce 8800 GTX is 100% quicker than the GeForce GT 440 3GB overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce 8800 GTX is much (more or less 158%) faster with regards to texture filtering 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

The GeForce GT 440 3GB should be a little bit (approximately 3%) more effective at AA than the GeForce 8800 GTX, and also should be capable of handling higher screen resolutions more effectively. (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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
