Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 440 1.5GB		56 Watts
	Difference: 25 Watts (81%)

Memory Bandwidth

In theory, the GeForce GT 440 1.5GB should be 238% faster than the GeForce GT 210 overall, because of its greater bandwidth. (explain)

GeForce GT 440 1.5GB		43200 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 30400 (238%)

Texel Rate

The GeForce GT 440 1.5GB should be much (more or less 203%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 9544 (203%)

Pixel Rate

The GeForce GT 440 1.5GB should be a lot (more or less 505%) more effective at anti-aliasing than the GeForce GT 210, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 11900 (505%)

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 (in units of MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
