Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Radeon R9 270 should perform a lot faster than the GeForce GTX 560 in general. (explain)

Radeon R9 270		179200 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 51072 (40%)

Texel Rate

The Radeon R9 270 should be much (about 59%) better at texture filtering than the GeForce GTX 560. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 26640 (59%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 270 is a better choice, but not by far. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 2880 (11%)

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 (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
