Radeon RX 5600		150 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically, the Radeon RX 5600 should be just a bit faster than the Radeon RX 6600 XT in general. (explain)

Radeon RX 5600		294912 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 6600 XT is a lot (about 43%) faster with regards to anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 75904 (43%)

Pixel Rate

The Radeon RX 6600 XT is quite a bit (about 43%) faster with regards to full screen anti-aliasing than the Radeon RX 5600, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 37952 (43%)

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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
