VS

GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

The GeForce RTX 2080 SUPER uses a 12 nm design. nVidia has clocked the core speed at 1650 MHz. The GDDR6 RAM runs at a speed of 1937 MHz on this particular model. It features 3072 SPUs along with 192 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6800, which comes with a clock speed of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Radeon RX 6800 should be a small bit faster than the GeForce RTX 2080 SUPER overall. (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 much (about 29%) faster with regards to anisotropic filtering 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 using lots of anti-aliasing 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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This 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 card will be at 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 can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
