GeForce GT 310		31 Watts
GeForce GTX 560		150 Watts
	Difference: 119 Watts (384%)

Memory Bandwidth

The GeForce GTX 560, in theory, should perform a lot faster than the GeForce GT 310 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 112128 (701%)

Texel Rate

The GeForce GTX 560 should be quite a bit (approximately 863%) more effective at AF than the GeForce GT 310. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 40648 (863%)

Pixel Rate

The GeForce GTX 560 should be quite a bit (more or less 1000%) faster with regards to full screen anti-aliasing than the GeForce GT 310, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 23564 (1000%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
