Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon R9 390 8G		275 Watts
	Difference: 125 Watts (83%)

Memory Bandwidth

Performance-wise, the Radeon R9 390 8G should in theory be a lot better than the Radeon RX 5600 in general. (explain)

Radeon R9 390 8G		384000 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 89088 (30%)

Texel Rate

The Radeon RX 5600 is just a bit (approximately 10%) more effective at texture filtering than the Radeon R9 390 8G. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R9 390 8G		160000 Mtexels/sec
	Difference: 16000 (10%)

Pixel Rate

The Radeon RX 5600 will be a lot (more or less 38%) faster with regards to full screen anti-aliasing than the Radeon R9 390 8G, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R9 390 8G		64000 Mpixels/sec
	Difference: 24000 (38%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
