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

Texel Rate

The Radeon RX 6800 XT is a lot (approximately 105%) better at anisotropic 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 quite a bit (more or less 127%) faster with regards to anti-aliasing than the GeForce RTX 2070 Super, and also should be capable of handling higher resolutions while still performing well. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
