Default An area where AMD server processors are more secure than Intel, thatwe pray never comes to desktop!

AMD's server Epyc processors have a security feature that doesn't even
exist in Intel yet: vendor-locked CPU's! If you install an Epyc
processor into certain servers from vendors like HP or Dell, that
processor will lock itself into that vendor and never work on any other
manufacturer's system again.

It's called PSB, Platform Secure Boot. The Epyc processor starts out as
a standard vendor-agnostic Epyc processor, but if it's installed into
one of these vendor's motherboards, during the first ever boot, the
motherboard BIOS will send the processor a lock code which will then
lock in that processor to that vendor forever! This is done to make sure
that no insecure code can be sent to modify the BIOS after that. Pretty
cool, but that also means that you can never sell that processor on the
used market again, after you're done with that particular processor.

Something like this coming to the client side would be a nightmare, as
selling old processors is a common thing. Did you know that this feature
existed? Intel processors can't do this yet, but Epyc processors have
been able to do this for 2 years already.
