Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 660 Ti should be a lot (about 150%) better at texture filtering than the GeForce GTX 560 Ti 448. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 61488 (150%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be a lot (about 33%) faster with regards to anti-aliasing than the GeForce GTX 660 Ti, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 7320 (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 MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few 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.
