GeForce RTX 2080 SUPER vs Radeon RX 5600 XT

Intro

Compare those specs to the Radeon RX 5600 XT, which has a clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be 48% faster than the Radeon RX 5600 XT in general, due to its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 163840 (48%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (approximately 60%) more effective at AF than the Radeon RX 5600 XT. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 118800 (60%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is the winner, not by a very large margin though. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 17600 (20%)

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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
