GeForce GT 320		25280 MB/sec
	Difference: 89920 (356%)

Texel Rate

The GeForce GTX 460 1GB will be quite a bit (more or less 192%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 24840 (192%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is superior to the GeForce GT 320, by a large margin. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 17280 (400%)

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 information (counted in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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.
