Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 480 4GB, in theory, should be a lot faster than the GeForce GTX 560 in general. (explain)

Radeon RX 480 4GB		229376 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 101248 (79%)

Texel Rate

The Radeon RX 480 4GB will be much (approximately 256%) more effective at texture filtering than the GeForce GTX 560. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 115920 (256%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 480 4GB is the winner, by far. (explain)

Radeon RX 480 4GB		35840 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 9920 (38%)

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 (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 graphics 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
