GeForce GT 430 1GB		60 Watts
GeForce GT 130		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

In theory, the GeForce GT 430 1GB will be 140% faster than the GeForce GT 130 in general, due to its greater data rate. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 16800 (140%)

Texel Rate

The GeForce GT 130 should be a bit (about 7%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 800 (7%)

Pixel Rate

The GeForce GT 130 will be quite a bit (more or less 186%) better at AA than the GeForce GT 430 1GB, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 5200 (186%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, 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 that the graphics card can possibly write to its local memory in one 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
