We've corrected the article. The Ryzen 7 5800U is Cezanne with Zen 3, while the others are Lucienne-based with Zen 2. Nice confusing naming conventions on the 5000-series Ryzen parts.The Ryzen 3 5300u, Ryzen 5 5500u and Ryzen 7 5700u are not Zen 3 Processors. They are Zen 2 based.
I ride Ub 20.04 without any issues. I did not try a lot on it though, this box have VM's, browsers sometimes simple game like factorio.If the Linux support is solid, then I'm definitely interested.
