GeForce GT 430 1GB		60 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 90 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 278% faster than the GeForce GT 430 1GB overall, due to its greater bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 80000 (278%)

Texel Rate

The GeForce GTX 460 SE is a lot (approximately 179%) better at AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 20000 (179%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is the winner, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 18000 (643%)

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 transferred past 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 type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
