Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 Ti will be 125% faster than the Radeon R7 M260X overall, due to its greater bandwidth. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 80000 (125%)

Texel Rate

The GeForce GTX 660 Ti will be quite a bit (about 418%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 82680 (418%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 Ti is superior to the Radeon R7 M260X, by far. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 15360 (233%)

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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 calculated by multiplying the total amount of 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
