Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER will be 94% quicker than the Radeon RX 6600 XT in general, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 245760 (94%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (about 26%) better at anisotropic filtering than the Radeon RX 6600 XT. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 64896 (26%)

Pixel Rate

The Radeon RX 6600 XT should be a small bit (more or less 19%) faster with regards to FSAA than the GeForce RTX 2080 SUPER, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 20352 (19%)

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 data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
