Radeon HD 5750 1GB		73600 MB/sec
	Difference: 60320 (82%)

Texel Rate

The GeForce GTX 470 should be quite a bit (approximately 35%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 470		33992 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 8792 (35%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 470 is the winner, by far. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 13080 (117%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
