Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti 2GB should in theory be just a bit superior to the Radeon HD 5750 1GB overall. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 650 Ti 2GB is much (more or less 136%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 34192 (136%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon HD 5750 1GB, by a large margin. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon HD 5750 1GB		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 information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
