Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should be 17% faster than the Radeon HD 5750 512MB in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 650 Ti will be much (more or less 136%) faster with regards to anisotropic filtering than the Radeon HD 5750 512MB. (explain)

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

Pixel Rate

The GeForce GTX 650 Ti should be a lot (about 33%) more effective at full screen anti-aliasing than the Radeon HD 5750 512MB, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 650 Ti		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: Memory bandwidth is the largest amount of information (counted 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. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
