Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 460 should be 17% faster than the Radeon HD 5750 1GB in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 460 should be quite a bit (more or less 50%) more effective at anisotropic filtering 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

The GeForce GTX 460 will be a lot (about 45%) faster with regards to FSAA than the Radeon HD 5750 1GB, and also will be able to handle higher resolutions without losing too much performance. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
