Radeon RX 590		175 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 125 Watts (71%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be much faster than the Radeon RX 590 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 262144 (100%)

Texel Rate

The Radeon RX 6900 XT should be a lot (about 176%) better at texture filtering than the Radeon RX 590. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 372464 (176%)

Pixel Rate

The Radeon RX 6900 XT is much (more or less 397%) faster with regards to full screen anti-aliasing than the Radeon RX 590, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 186592 (397%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
