Radeon HD 5750 512MB		86 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 24 Watts (28%)

Memory Bandwidth

In theory, the GeForce GTX 650 Ti 2GB should be 17% quicker than the Radeon HD 5750 512MB in general, due to its greater bandwidth. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (about 136%) faster with regards to texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 34192 (136%)

Pixel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (about 33%) more effective at full screen anti-aliasing than the Radeon HD 5750 512MB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 3648 (33%)

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 (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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