GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon HD 4670 1GB will be quite a bit (more or less 114%) faster with regards to anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon HD 4670 1GB		24000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 12800 (114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4670 1GB is the winner, and very much so. (explain)

Radeon HD 4670 1GB		6000 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 3200 (114%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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