I’m actually excited for this. Apple is working wonders with ipc/single threaded performance improvements with their custom arm cores much more than Intel/AMD’s x86, while maintaining a massive lead in perf per watt efficiency. If any one can pull it off, it has to be Apple since they probably the most vertically integrated tech company on the planet and their software ecosystem is very much under their complete control. Im quite sure Intel/AMD sees this move as a disruptive threat or the x86/amd64 hegemony in the traditional computing. Imagine ARM on Macs, PCs, smartphones, tablets, consoles, enterprise/datacenter, hpc, etc.
