Radeon RX 5600 XT		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6800 XT will be much (more or less 165%) better at texture filtering than the Radeon RX 5600 XT. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 327600 (165%)

Pixel Rate

The Radeon RX 6800 XT is much (more or less 165%) faster with regards to AA than the Radeon RX 5600 XT, and also able to handle higher resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 5600 XT		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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
