Radeon HD 7750		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 SE is much (more or less 22%) faster with regards to AF than the Radeon HD 7750. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 5600 (22%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 7750, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 8000 (63%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
