Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 1.5GB		56 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 94 Watts (168%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 152% faster than the GeForce GT 440 1.5GB overall, because of its higher data rate. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 65600 (152%)

Texel Rate

The GeForce GTX 460 SE is quite a bit (more or less 119%) faster with regards to anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 16944 (119%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is the winner, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 6544 (46%)

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 megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
