Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 5600		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 should be 157% faster than the Radeon RX 550 overall, because of its higher bandwidth. (explain)

Radeon RX 5600		294912 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 180224 (157%)

Texel Rate

The Radeon RX 5600 will be a lot (more or less 400%) faster with regards to texture filtering than the Radeon RX 550. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 140800 (400%)

Pixel Rate

The Radeon RX 5600 is quite a bit (approximately 400%) more effective at anti-aliasing than the Radeon RX 550, and also able to handle higher resolutions better. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 70400 (400%)

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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total 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 in a second.

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