Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M295X		125 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 45 Watts (36%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X will be 37% faster than the GeForce GTX 560 Ti in general, due to its greater bandwidth. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GTX 560 Ti		128256 MB/sec
	Difference: 47744 (37%)

Texel Rate

The Radeon R9 M295X will be quite a bit (more or less 82%) faster with regards to anisotropic filtering than the GeForce GTX 560 Ti. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 560 Ti		52608 Mtexels/sec
	Difference: 43392 (82%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, though only just barely. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 2304 (10%)

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 information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
