GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

The GeForce RTX 2080 SUPER features a GPU core clock speed of 1650 MHz, and the 8192 MB of GDDR6 memory runs at 1937 MHz through a 256-bit bus. It also is comprised of 3072 Stream Processors, 192 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX 6800, which features a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also features 3840 SPUs, 240 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should theoretically perform a little bit faster than the GeForce RTX 2080 SUPER in general. (explain)

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

Texel Rate

The Radeon RX 6800 should be quite a bit (more or less 29%) better at AF than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 6800 408000 Mtexels/sec
GeForce RTX 2080 SUPER 316800 Mtexels/sec
Difference: 91200 (29%)

Pixel Rate

The Radeon RX 6800 is a lot (about 55%) better at anti-aliasing than the GeForce RTX 2080 SUPER, and will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6800 163200 Mpixels/sec
GeForce RTX 2080 SUPER 105600 Mpixels/sec
Difference: 57600 (55%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
