Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
GeForce RTX 2080 Ti		250 Watts
	Difference: 15 Watts (6%)

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti should be much faster than the Radeon RX 5700 XT 50th Anniversary Edition overall. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
	Difference: 172032 (38%)

Texel Rate

The GeForce RTX 2080 Ti should be much (approximately 37%) more effective at texture filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
	Difference: 98400 (37%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 Ti is superior to the Radeon RX 5700 XT 50th Anniversary Edition, but it probably won't make a huge difference. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
	Difference: 11280 (10%)

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 transferred over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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.
