Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X will be 11% faster than the GeForce 8800 GT 512MB overall, because of its higher bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 8800 GT 512MB should be much (approximately 70%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 13800 (70%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 GT 512MB is superior to the Radeon R7 M260X, and very much so. (explain)

GeForce 8800 GT 512MB		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 max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied per 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 better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
