The Radeon HD 6950 2GB is much (more or less 529%) faster with regards to AF than the GeForce GT 430 (OEM). (explain)

Radeon HD 6950 2GB		70400 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 59200 (529%)

Pixel Rate

The Radeon HD 6950 2GB should be quite a bit (approximately 814%) more effective at AA than the GeForce GT 430 (OEM), and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 6950 2GB		25600 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 22800 (814%)

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 (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
