Radeon RX 5500 XT		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 XT is a lot (approximately 248%) more effective at texture filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 374504 (248%)

Pixel Rate

The Radeon RX 6800 XT will be much (about 325%) better at full screen anti-aliasing than the Radeon RX 5500 XT, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 178656 (325%)

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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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