Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 650 should theoretically be quite a bit better than the Radeon R7 M260X overall. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 16000 (25%)

Texel Rate

The GeForce GTX 650 is quite a bit (more or less 71%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 650		33856 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 14056 (71%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 is a better choice, by far. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 10328 (156%)

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 data (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
