Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 150 Watts (100%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT should be 78% faster than the Radeon RX 5600 overall, because of its greater bandwidth. (explain)

Radeon RX 6800 XT		524288 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 229376 (78%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 199%) faster with regards to AF than the Radeon RX 5600. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 349600 (199%)

Pixel Rate

The Radeon RX 6800 XT is a lot (about 165%) faster with regards to full screen anti-aliasing than the Radeon RX 5600, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 145600 (165%)

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 (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
