GeForce GT 440 1.5GB		43200 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 4800 (13%)

Texel Rate

The GeForce 8800 GS is much (more or less 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

If using a high screen resolution is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce 8800 GS, and very much so. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
