GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

The GeForce RTX 2080 SUPER features a GPU clock speed of 1650 MHz, and the 8192 MB of GDDR6 RAM is set to run at 1937 MHz through a 256-bit bus. It also is comprised of 3072 Stream Processors, 192 Texture Address Units, and 64 ROPs.

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should in theory be just a 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 is a lot (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

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 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
