In theory, the GeForce GTX 560 Ti 448 should be 96% faster than the Radeon HD 5750 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 70400 (96%)

Texel Rate

The GeForce GTX 560 Ti 448 will be quite a bit (approximately 63%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 15792 (63%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be much (approximately 161%) more effective at FSAA than the Radeon HD 5750 1GB, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 18080 (161%)

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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
