Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
Radeon RX 560		80 Watts
	Difference: 37 Watts (86%)

Memory Bandwidth

In theory, the Radeon RX 560 should be 298% faster than the Radeon HD 5570 overall, because of its higher data rate. (explain)

Radeon RX 560		114688 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 85888 (298%)

Texel Rate

The Radeon RX 560 will be much (more or less 478%) better at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 62200 (478%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is superior to the Radeon HD 5570, by a large margin. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 13600 (262%)

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 MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
