I'm a little bit surprised that Apple hasn't moved beyond 128-bit NEON, either with a custom 256 bit extension, or with an early implementation of SVE. This seems to be an area where vertical integration of software makes transitions easier -- getting Accelerate.framework over to something wider would have immediate pay-off, and especially at higher power budgets it seems clear from looking at the rest of the industry that somewhat wider vectors is a good perf to area trade-off.
