GeForce RTX 2080 Ti vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which has GPU core speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also features 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti should perform a small bit faster than the Radeon RX 6800 in general. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 6800		524288 MB/sec
	Difference: 106496 (20%)

Texel Rate

The Radeon RX 6800 will be a bit (approximately 11%) better at anisotropic filtering than the GeForce RTX 2080 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 40800 (11%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 is the winner, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 44400 (37%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant 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.
