Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 185 Watts (370%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT 50th Anniversary Edition should be 300% faster than the Radeon RX 550 overall, due to its greater data rate. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 344064 (300%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be quite a bit (approximately 664%) more effective at texture filtering than the Radeon RX 550. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 233600 (664%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is a lot (more or less 511%) faster with regards to AA than the Radeon RX 550, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 89920 (511%)

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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The better the texel rate, the better the video card will be at handling 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 video card can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
