For me personally, big navi is not fully exploitable as we don't have great software to run that requires all that power. Of course for those who have to buy now, maybe it is better to wait, but I repeat, it does not seem to me that with the software currently available for Power, we can unfortunately take advantage of a card like the big navi. So in summary, you tell me that if you install one of those packages on Debian, can you use Navi? But are there no real drivers now, given the time that has passed since the release of Navi 10/14 ?!
