Memory Bandwidth

Performance-wise, the GeForce GTX 750 Ti should in theory be a bit better than the Radeon HD 5750 512MB overall. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 750 Ti should be quite a bit (about 62%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 15600 (62%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is a better choice, and very much so. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 5120 (46%)

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 (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many 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.
