GeForce GT 130		75 Watts
GeForce GTX 560		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the GeForce GTX 560 will be 968% quicker than the GeForce GT 130 overall, due to its greater bandwidth. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 116128 (968%)

Texel Rate

The GeForce GTX 560 is quite a bit (approximately 278%) faster with regards to AF than the GeForce GT 130. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 33360 (278%)

Pixel Rate

The GeForce GTX 560 is a lot (about 224%) faster with regards to anti-aliasing than the GeForce GT 130, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 17920 (224%)

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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
