Doesn’t require the absolute latest processes.
It reminded me that for a while all SIM everywhere seemed to come from one european chip plant, although now I say it I wonder if they were just the assembly & packaging and fabrication was offshore?
In both cases (tpm and sim) the cynic would say it's only deciding which economy owns the back-door.
Semiconductor manufacturing is an exercise in blood, tears and careful note taking, not Magic Secrets.
Isn't this a ringing success for their strategy of separating chip design from fabrication?
Though, if this goes well, it stands to reason Apple may be that needed commitment.
