GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 25600 (89%)

Texel Rate

The GeForce GT 340 1GB will be quite a bit (about 57%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 6400 (57%)

Pixel Rate

The GeForce GT 340 1GB is quite a bit (more or less 57%) faster with regards to full screen anti-aliasing than the GeForce GT 430 (OEM), and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GT 340 1GB		4400 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 1600 (57%)

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 transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total 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 in a second.

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