I apologize if this is a bad question or has already been asked. Why doesn’t intel (or AMD) create a socket with the maximum amount of pins possible that way every new CPU would be compatible with a bios update? Even if new gen CPUs don’t utilize all the pins it would leave headroom for new generations. Is it not possible going from 10nm to 7nm? Imagine creating LGA 3000 that could support the next 10 generations.
Cpu sockets are expensive parts, you are not going to use a socket with 5000 pins if you don’t need this many.
