GeForce 8800 GTS (G80) 640MB		24624 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 13424 (120%)

Pixel Rate

The GeForce 8800 GTS (G80) 640MB should be quite a bit (approximately 266%) faster with regards to AA than the GeForce GT 430 (OEM), and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce 8800 GTS (G80) 640MB		10260 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 7460 (266%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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