Radeon RX 5700 XT		225 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 75 Watts (33%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be 14% quicker than the Radeon RX 5700 XT in general, because of its greater bandwidth. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT will be a lot (approximately 127%) better at texture filtering than the Radeon RX 5700 XT. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 327200 (127%)

Pixel Rate

The Radeon RX 6900 XT should be a lot (more or less 127%) faster with regards to FSAA than the Radeon RX 5700 XT, and also should be able to handle higher resolutions better. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 130880 (127%)

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 largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
