GeForce GTX 560 Ti 448		210 Watts
GeForce GTX 280		236 Watts
	Difference: 26 Watts (12%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti 448 should be a little bit faster than the GeForce GTX 280 in general. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
GeForce GTX 280		141696 MB/sec
	Difference: 2304 (2%)

Texel Rate

The GeForce GTX 280 should be a little bit (about 17%) better at AF than the GeForce GTX 560 Ti 448. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 7168 (17%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be quite a bit (more or less 52%) more effective at AA than the GeForce GTX 280, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 10016 (52%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The higher this number, the better the 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
