As far as performance goes, the Radeon RX 5600 XT should theoretically be just a bit better than the GeForce GTX 1080 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 16384 (5%)

Texel Rate

The GeForce GTX 1080 is quite a bit (more or less 30%) faster with regards to anisotropic filtering than the Radeon RX 5600 XT. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 59120 (30%)

Pixel Rate

The GeForce GTX 1080 will be a small bit (more or less 17%) faster with regards to full screen anti-aliasing than the Radeon RX 5600 XT, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 14848 (17%)

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 MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
