I have been told by people who worked on them that you get radiation hardened aerospace/defence grade chips by backing off the clock speed about 20% to give signal stabilization slightly longer time. I can understand the population being confused about this but industry being confused seems to have more to do with regulatory capture and beaurocratic moats which SpaceX does seem to be bypassing.
