I was under the impression that 5600g and 5600u were Zen3, but being the APU models they have Radeon graphics.

Anecdotally, I tried to reproduce on my 5600g but couldn't. Which is surprising because they claim it works on 5700u...

Edit: just discovered that while my 5600g is Zen3, the 5700u is Zen2. Lol.
