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

Texel Rate

The GeForce GTX 460 1GB will be much (more or less 238%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is superior to the GeForce GT 430 (OEM), by far. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GT 430 (OEM)		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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
