I'm as skeptical as the next person, but.. Apple's track record on delivering solid performance improvement year after year in their chips has been solid for quite a while now.. [1]
It'd be more surprising at this point if it _wasn't_ more powerful.
> I find it hard to believe that their next chips will be more powerful.
>Whilst in the past 5 years Intel has managed to increase their best single-thread performance by about 28%, Apple has managed to improve their designs by 198%, or 2.98x (let’s call it 3x) the performance of the Apple A9 of late 2015.
They wouldn't have announced the full transition if they weren't confident they could deliver. They would have kept the ARM for the low end models and Intel for the high end.
