GeForce RTX 2080 Ti vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 RAM runs at a frequency of 2000 MHz on this specific card. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 Ti will be 20% quicker than the Radeon RX 6800 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6800 should be a bit (about 11%) more effective at texture 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 a better choice, 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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
