VS

GeForce RTX 2080 SUPER vs Radeon RX 6800

Intro

The GeForce RTX 2080 SUPER features core clock speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 memory. It features 3072 SPUs along with 192 TAUs and 64 ROPs.

Compare all of that to the Radeon RX 6800, which has clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 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, in theory, should perform a small 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 will 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 running with high levels of AA is important to you, then the Radeon RX 6800 is a better choice, by far. (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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

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