VS

GeForce RTX 2080 SUPER vs Radeon RX 6900 XT

Intro

The GeForce RTX 2080 SUPER makes use of a 12 nm design. nVidia has clocked the core speed at 1650 MHz. The GDDR6 RAM works at a speed of 1937 MHz on this model. It features 3072 SPUs as well as 192 Texture Address Units and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX 6900 XT, which has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER 250 Watts
Radeon RX 6900 XT 300 Watts
Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should be 3% quicker than the GeForce RTX 2080 SUPER in general, because of its higher data rate. (explain)

Radeon RX 6900 XT 524288 MB/sec
GeForce RTX 2080 SUPER 507904 MB/sec
Difference: 16384 (3%)

Texel Rate

The Radeon RX 6900 XT should be a lot (about 84%) more effective at AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
GeForce RTX 2080 SUPER 316800 Mtexels/sec
Difference: 267200 (84%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 2080 SUPER, by a large margin. (explain)

Radeon RX 6900 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
