They’re equally stable, i’ve been on nothing but intel for decades and it was always fine, but then ryzen came and i finally got an amd powered laptop with a ryzen 6900hx, and it’s also completely fine, there was a tpm problem with it for like a good year though that lead to the system freezing up randomly for a few seconds (it also happened on windows though) but it’s been ‘fixed’ by removing support for a feature that was fundamentally broken.
It’s kinda funny, tpm does nothing of value and only causes problems, why do we even have this shit.
