	Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 1GB will be quite a bit (more or less 124%) faster with regards to AF than the Radeon HD 6450 (OEM). (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 6200 (124%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 430 1GB is the winner, though only just barely. (explain)

GeForce GT 430 1GB		2800 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 300 (12%)

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 (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 number of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
