I'm running Beowulf on a (desktop) Ryzen 5 3600.  The only issue I had
initially was I needed a newer kernel (the backports one is good) for
the motherboard sensors.  Oh and I think my motherboard audio has driver
problems that I never got sorted out, but I use USB headphones.  As to
performance and reliability, I'm pleased with both.  Considering another
Ryzen when it's time to upgrade again (this is my first AMD desktop system).
