Radeon RX 560		80 Watts
GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 91 Watts (114%)

Memory Bandwidth

In theory, the Radeon RX 560 should be 3% quicker than the GeForce GTX 260 216SP 55 nm overall, because of its higher bandwidth. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 260 216SP 55 nm		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The Radeon RX 560 should be quite a bit (more or less 81%) more effective at anisotropic filtering than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
	Difference: 33728 (81%)

Pixel Rate

The Radeon RX 560 will be a little bit (about 17%) more effective at full screen anti-aliasing than the GeForce GTX 260 216SP 55 nm, and also able to handle higher resolutions better. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
	Difference: 2672 (17%)

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 (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 maximum fill rate.
