GeForce RTX 2080 vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this specific model. It features 3840 SPUs as well as 240 TAUs and 96 ROPs.

GeForce RTX 2080		278760 Mtexels/sec
	Difference: 129240 (46%)

Pixel Rate

The Radeon RX 6800 should be a lot (approximately 68%) faster with regards to AA than the GeForce RTX 2080, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 66240 (68%)

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 past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
