Radeon HD 5750 1GB		86 Watts
GeForce GTX 460		150 Watts
	Difference: 64 Watts (74%)

Memory Bandwidth

In theory, the GeForce GTX 460 will be 17% quicker than the Radeon HD 5750 1GB overall, due to its higher bandwidth. (explain)

GeForce GTX 460		86400 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 460 is quite a bit (about 50%) better at AF than the Radeon HD 5750 1GB. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 12600 (50%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 is a better choice, and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 5000 (45%)

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 (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
