@gabrielesvelto @wlach @eniko CPUs have recently become more and more buggy.

Intel in the core 2 Duo days intentionally released untested buggy garbage and later fixed some of the most severe bugs via proprietary software microcode updates (that definitely doesn't also contain malware), but even then, those are still plenty stable for 20 hour Church of Emacs sessions and 20 hour compiling session, but good luck trying to watch slop videos for >20 minutes.

Intel has only gotten worse, with CPUs that fry themselves with voltage.

AMD did previously actually deliver decent products from the factory - for example the Opteron 62XX series are very stable without any proprietary software updates, but later CPUs like Ryzen are buggy garbage.
