It’s a bit strange that it won’t be on the iPhone 14 pro and 15 non pro, especially since it will be available for m1 iPads which should be a slightly weaker NPU than in the A16 bionic, both NPUs are 16 core, but the M1 is on an older less efficient node. Geekbench ML scores for m1 iPad Pro is 2688, A16 Bionic (iPhone 14 pro max) is 3231 both NPU only cores, so I don’t know why M1 iPad Pro/air are getting the feature and not A16 Bionic devices. Even A14 Bionic devices like the iPhone SE (2022) are getting higher NPU ML scores than the M1 at 2772. but what do I know, I’m only a user not a dev. I don’t know what other factors are at play in their decision.
