Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon R9 390X 8G		275 Watts
	Difference: 115 Watts (72%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 390X 8G should be 12% faster than the Radeon RX 5600 XT in general, because of its higher bandwidth. (explain)

Radeon R9 390X 8G		384000 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 39936 (12%)

Texel Rate

The Radeon RX 5600 XT is a little bit (about 7%) better at texture filtering than the Radeon R9 390X 8G. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 390X 8G		184800 Mtexels/sec
	Difference: 13200 (7%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 XT is superior to the Radeon R9 390X 8G, and very much so. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 390X 8G		67200 Mpixels/sec
	Difference: 20800 (31%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
