Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 780 Ti, in theory, should perform quite a bit faster than the Radeon R7 M260X in general. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 272000 (425%)

Texel Rate

The GeForce GTX 780 Ti will be a lot (about 961%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 190200 (961%)

Pixel Rate

The GeForce GTX 780 Ti is quite a bit (approximately 536%) more effective at full screen anti-aliasing than the Radeon R7 M260X, and capable of handling higher screen resolutions better. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 35400 (536%)

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 data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
