Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 660 Ti will be 67% faster than the GeForce GTX 460 overall, due to its greater bandwidth. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 57600 (67%)

Texel Rate

The GeForce GTX 660 Ti is quite a bit (more or less 171%) better at AF than the GeForce GTX 460. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 64680 (171%)

Pixel Rate

The GeForce GTX 660 Ti should be a lot (approximately 36%) better at FSAA than the GeForce GTX 460, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 5760 (36%)

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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
