From M1 Max’s silicon bridge with micro-bumps to M5’s Cu–Cu hybrid bonding, Apple is pushing interconnect technology to the next level. By separating CPU and GPU and reconnecting them through advanced bonding, Apple is not just scaling performance—it’s redefining how chips communicate at the package level.
This is no longer just chip design.
It’s system architecture through packaging.
