GeForce RTX 2080		215 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 15 Watts (7%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 should in theory be just a bit superior to the Radeon RX 6700 XT overall. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 65536 (17%)

Texel Rate

The Radeon RX 6700 XT will be a lot (approximately 33%) better at AF than the GeForce RTX 2080. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 92600 (33%)

Pixel Rate

The Radeon RX 6700 XT is quite a bit (about 53%) better at anti-aliasing than the GeForce RTX 2080, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 51584 (53%)

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 transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 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 get to the maximum fill rate.
