GeForce GT 430		28800 MB/sec
	Difference: 86400 (300%)

Texel Rate

The GeForce GTX 460 1GB will be quite a bit (approximately 238%) better at AF than the GeForce GT 430. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 26600 (238%)

Pixel Rate

The GeForce GTX 460 1GB should be much (more or less 671%) more effective at anti-aliasing than the GeForce GT 430, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 18800 (671%)

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 data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
