Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 560 should be quite a bit faster than the Radeon R9 M270X in general. (explain)

GeForce GTX 560		128128 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 56128 (78%)

Texel Rate

The GeForce GTX 560 will be a lot (approximately 56%) better at anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 16360 (56%)

Pixel Rate

The GeForce GTX 560 will be much (more or less 123%) faster with regards to FSAA than the Radeon R9 M270X, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 14320 (123%)

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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
