GeForce RTX 2070 Super		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 XT will be a lot (more or less 105%) more effective at texture filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 268800 (105%)

Pixel Rate

The Radeon RX 6800 XT is much (about 127%) more effective at anti-aliasing than the GeForce RTX 2070 Super, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 130880 (127%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
