Power Consumption (Max TDP)

GeForce GTX 660 Ti		150 Watts
Geforce GTX 670		170 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

As far as performance goes, the Geforce GTX 670 should in theory be a lot better than the GeForce GTX 660 Ti in general. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 48000 (33%)

Texel Rate

Both cards have the exact same texel rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 670 is the winner, and very much so. (explain)

Geforce GTX 670		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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
