Troughton-Smith notes on Twitter that the A10 Fusion chip would let “Apple experiment with tighter control” of macOS, without frustrating developers and users.
Furthermore, he explains that the A10 Fusion chip in the iMac Pro could be used for always-on “Hey, Siri,” a feature that’s currently missing from the macOS version of Siri. In fact, Troughton-Smith says in appears that the chip even runs when the iMac Pro is completely shut off.
A report over the summer explained that the iMac Pro would feature an ARM coprocessor, and today’s information seems to further confirm that with a bit more information.
It’s unclear how the A10 Fusion chip seemingly destined for the iMac Pro fits into all of this, but it’s certainly notable that Apple is testing the waters with bringing its A-series chips to the Mac. How the supposed A10 Fusion chip in the iMac Pro will differ from other coprocessor technology Apple has used remains to be seen.
