Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 should be quite a bit faster than the Radeon HD 5550 overall. (explain)

Radeon RX 560		114688 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 101888 (796%)

Texel Rate

The Radeon RX 560 is quite a bit (approximately 755%) faster with regards to AF than the Radeon HD 5550. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 66400 (755%)

Pixel Rate

The Radeon RX 560 should be quite a bit (about 327%) faster with regards to anti-aliasing than the Radeon HD 5550, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 14400 (327%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
