Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 11% quicker than the GeForce 8800 GT 1GB overall, due to its higher data rate. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 8800 GT 1GB will be a lot (approximately 70%) better at texture filtering than the Radeon R7 M260X. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 13800 (70%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GT 1GB is a better choice, and very much so. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 3000 (45%)

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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
