I hear the claim of apple super arms chips and don't really have anything to deny it, however, can testing be really oranges to oranges? Is an iphone chip being challenged by the same demands as a chip in a desktop?I think you mistake ARM as low end chips. ARM is just an architecture. The Apple A11 is 5-10x faster then the chips you find in the cheapo $100 chromebooks. The A11 in the current iphones is actually faster then the mid range 4 core i5s. If Apple does switch their laptop/desktop machines they won't be using A11s. They will be using A12x or A13 with custom ASIC designed for those machines. Yes Intel should be very worried, even if Apple doesn't switch in the next few years to their own custom ARM chips. ARM is with out a doubt starting to gain serious traction in Servers and even Super computing.
