Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 560 will be 19% quicker than the Radeon R9 M385X in general, because of its greater data rate. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 will be much (approximately 22%) better at texture filtering than the Radeon R9 M385X. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 13600 (22%)

Pixel Rate

The Radeon RX 560 will be a little bit (more or less 7%) better at anti-aliasing than the Radeon R9 M385X, and will be able to handle higher resolutions more effectively. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 1200 (7%)

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 information (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This is calculated by multiplying the total amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 max fill rate.
