Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
Radeon RX 560		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

In theory, the Radeon RX 560 should be 2% quicker than the Radeon RX 460 overall, due to its greater bandwidth. (explain)

Radeon RX 560		114688 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 2688 (2%)

Texel Rate

The Radeon RX 560 is quite a bit (approximately 23%) faster with regards to texture filtering than the Radeon RX 460. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 14160 (23%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is superior to the Radeon RX 460, though only just barely. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 1360 (8%)

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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core 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 amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
