GeForce RTX 2080 SUPER vs Radeon RX 6800 XT

Intro

The GeForce RTX 2080 SUPER features a core clock frequency of 1650 MHz and a GDDR6 memory speed of 1937 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It is made up of 3072 SPUs, 192 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6800 XT, which features a clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It features 4608 SPUs, 288 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER 250 Watts
Radeon RX 6800 XT 300 Watts
Difference: 50 Watts (20%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 XT should in theory be just a bit superior to the GeForce RTX 2080 SUPER in general. (explain)

Radeon RX 6800 XT 524288 MB/sec
GeForce RTX 2080 SUPER 507904 MB/sec
Difference: 16384 (3%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (about 66%) faster with regards to AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
GeForce RTX 2080 SUPER 316800 Mtexels/sec
Difference: 208800 (66%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 XT is the winner, by a large margin. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
GeForce RTX 2080 SUPER 105600 Mpixels/sec
Difference: 128000 (121%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
