Texel Rate

The GeForce GTX 460 SE is a lot (more or less 24%) more effective at texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 6000 (24%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 5750 512MB, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 9600 (86%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
