Radeon RX 560		80 Watts
Radeon HD 5830		175 Watts
	Difference: 95 Watts (119%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 will be 12% faster than the Radeon RX 560 in general, due to its greater data rate. (explain)

Radeon HD 5830		128000 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 13312 (12%)

Texel Rate

The Radeon RX 560 is quite a bit (about 68%) better at texture filtering than the Radeon HD 5830. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 30400 (68%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 560 is a better choice, by far. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 6000 (47%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out 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 it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
