The IBM z9 processor, if I remember correctly, can do the comparison in hardware. When the cores consistently fail to match, the system can probably also call the IBM service technician.
The z-series stuff is indeed some amazing piece of kit.
Yes, the machine can and does call the technician when something fails. And iirc everything, including the CPUs, is hot-swappable. That means you can physically remove a CPU-book (containing processors and RAM) and your OS will keep running.
Quite a nerds dream, if you have the spare change...
