Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 140 Watts (88%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT will be 52% faster than the GeForce RTX 2060 in general, due to its higher data rate. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6800 XT will be quite a bit (about 221%) better at AF than the GeForce RTX 2060. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 361800 (221%)

Pixel Rate

The Radeon RX 6800 XT should be a lot (more or less 257%) faster with regards to AA than the GeForce RTX 2060, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 168080 (257%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card can 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
