Not sure. They sound a bit similar to the problems with 13/14g andI can well imagine intel wanting to downplay any problems. intel have history for self destroying CPUs too (I had a bunch of Atom C2000 machines and that was handled very poorly). > 2. Ryzen models don't have problems with stability and/or damages to cpu? Not so much and at least they did exchanges with the Ryzen 7000 problems... But I think I've heard of more problems with AMD GPU drivers having problems on OpenBSD than Intel (also AMD don't have control-flow protection in their CPUs yet, which heavily mitigates some classes of attack on OS and programs which use it). For productive "normal user" use I'd probably go for 11/12th gen intel on laptops/workstations and Ryzen on things doing more compute (compiling code, etc). (arm64 can be good in some cases too but openbsd is less polished there, hardware choice is trickier too). -- Please keep replies on the mailing list.
