Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 320		43 Watts
	Difference: 12 Watts (39%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 320 will be 98% quicker than the GeForce GT 210 in general, due to its greater bandwidth. (explain)

GeForce GT 320		25280 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 12480 (98%)

Texel Rate

The GeForce GT 320 should be a lot (about 175%) faster with regards to texture filtering than the GeForce GT 210. (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 8248 (175%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 320 is superior to the GeForce GT 210, by a large margin. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 1964 (83%)

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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
