GeForce GTX 465		200 Watts
GeForce GTX 560 Ti 448		210 Watts
	Difference: 10 Watts (5%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 should be 40% faster than the GeForce GTX 465 in general, because of its greater bandwidth. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 41408 (40%)

Texel Rate

The GeForce GTX 560 Ti 448 should be a lot (about 53%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 14284 (53%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti 448 is the winner, and very much so. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 9856 (51%)

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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 card's clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
