Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti, in theory, should perform much faster than the Radeon R7 M260X overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (more or less 200%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 39592 (200%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is the winner, by a large margin. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 8248 (125%)

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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
