GeForce RTX 2080		215 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 120 Watts (56%)

Memory Bandwidth

Theoretically, the Radeon RX 6950 XT should be a lot faster than the GeForce RTX 2080 overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 131072 (29%)

Texel Rate

The Radeon RX 6950 XT will be much (more or less 121%) more effective at anisotropic filtering than the GeForce RTX 2080. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 337240 (121%)

Pixel Rate

The Radeon RX 6950 XT will be quite a bit (approximately 154%) more effective at FSAA than the GeForce RTX 2080, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 149440 (154%)

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 (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
