Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 560		150 Watts
	Difference: 107 Watts (249%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should be 407% faster than the GeForce GT 320 in general, because of its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 102848 (407%)

Texel Rate

The GeForce GTX 560 should be much (about 250%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 32400 (250%)

Pixel Rate

The GeForce GTX 560 will be much (more or less 500%) better at AA than the GeForce GT 320, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 21600 (500%)

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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are processed in one second. This figure 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 in one second.

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