AMD Radeon RX 6800 16GB GPU Review


AMD Radeon RX 6800 Specifications

First, here are the key specs directly from the AMD website (as of the date of this article):

You may notice that the release date was November 2020. It has taken us this long to get these cards.

One key specification for the AMD Radeon RX 6800 is that it uses 16GB GDDR6 memory. This is more than the MSI GeForce RTX 3070 and RTX 3080.

Testing the AMD Radeon RX 6800

Here is our test configuration:

Here is the obligatory GPU-Z shot of the AMD Radeon RX 6800:

GPU-Z shows the primary stats of our testing the AMD Radeon RX 6800. The GPU clocks in at 1815 MHz and can boost up to 2105 MHz. Pixel Fillrates run at 101.0 GPixels/s, and Texture Fillrate comes in at 505.2 GTexel/s, while memory runs at 2000 MHz. We see 16GB of GDDR6 memory on the AMD Radeon RX 6800.

Let us move on and start our testing with computing-related benchmarks.


  1. Will you include video encoding benchmarks? Given how popular Plex is in the home lab space, I would expect video encoding to be very relevant.

  2. Wanna know the real dirty little secret woth your new card, William? ROCm does not support RDNA GPUs. The last AMD consumer cards that ROCm supported was the Vega 56/64 and it’s 7nM die shrink the VII.

    You got a RX5000 or RX6000 series card or any version of APU, well you get to use OpenCL. Aren’t you lucky?

    nVidia supported CUDA on every GPU since at least the 8800GT. I can’t imagine how AMD expects to get ROCm out of the upcoming national labs when the only modern card it will work on is the mi100. Ever try to buy an mi100 (or mi50)? It is basically possible to find an AMD reseller that will even condescend to speak to a small ISV.

  3. I find all these reviews and release news for both AMD and Nvidia card a joke at the moment, as an end user I can’t ever find any in stock no matter how deep my pockets!!

    I’m not just talking about STH

  4. Pure junk selling, USA warranty evading, AMD still owes me a video board since I did not even get a 1/2 year of performance from the 3 very poorly designed and QA, Vega Frontier Editions.
    AMD wanting all the selfish benefits of consumer sales, but none of the mature responsibilities.

  5. The replacement warranty boards from AMD all junk. The first not lasting more than 2 days without crashing (BSD), the second, having waited ~1 mth, just 1 day then crashing. I having the impression, no one watching AMD, hey simply return “defective boards” as replacements, then wash their foul hands, not honoring anything, their word to then not respecting customer.
    Worst, this company then sought to abuse USA Consumer Protection Laws by expecting their customers in the USA to send the defective product OUT OF COUNTRY, having no USA depot.
