Radeon RX 5500 XT		130 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 30 Watts (23%)

Memory Bandwidth

The Radeon RX 6600 XT, in theory, should be a small bit faster than the Radeon RX 5500 XT overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 XT is much (more or less 67%) better at anisotropic filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 100808 (67%)

Pixel Rate

The Radeon RX 6600 XT should be quite a bit (about 129%) better at full screen anti-aliasing than the Radeon RX 5500 XT, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 71008 (129%)

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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 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, HDR and high resolutions.

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

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