Radeon HD 5750 1GB		73600 MB/sec
	Difference: 28992 (39%)

Texel Rate

The GeForce GTX 465 should be a bit (more or less 6%) faster with regards to anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 1508 (6%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is superior to the Radeon HD 5750 1GB, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 8224 (73%)

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 information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
