GeForce GT 430 1GB		60 Watts
GeForce GTX 560		150 Watts
	Difference: 90 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 will be 345% faster than the GeForce GT 430 1GB in general, due to its greater bandwidth. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 99328 (345%)

Texel Rate

The GeForce GTX 560 will be quite a bit (approximately 305%) better at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 34160 (305%)

Pixel Rate

The GeForce GTX 560 is a lot (approximately 826%) better at AA than the GeForce GT 430 1GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 23120 (826%)

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 (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
