Their chips aren't any better, in fact they're probably quite a few generations behind what's available commercially due to various certification requirements etc. HOWEVER, last I checked, their budget for this sort of thing was 11 billion dollars a year, and that's where their advantage lies. Their chips are designed to be maximally power performant for the tasks they're doing, and they have a fuckton of them.
