Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Geforce GTX 680		195 Watts
	Difference: 152 Watts (353%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 680 will be 661% quicker than the GeForce GT 320 in general, due to its higher bandwidth. (explain)

Geforce GTX 680		192256 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 166976 (661%)

Texel Rate

The Geforce GTX 680 will be quite a bit (more or less 894%) better at AF than the GeForce GT 320. (explain)

Geforce GTX 680		128768 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 115808 (894%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 680 is superior to the GeForce GT 320, by far. (explain)

Geforce GTX 680		32192 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 27872 (645%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 most pixels that the graphics card could possibly write to the local memory in one 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
