"The iPhone and iPad have run on Apple-designed ARM chips since birth, and while early entries into the Axx line were underpowered, the latest chips created by Apple’s silicon design teams have yielded laptop- or even desktop-class performance" This is incorrect. iPhone's SoC until iPhone 4 was a 32 bit ARM Samsung SoC [1]. From iPhone 4 and onwards they were designed by Apple. The first iPad also had a SoC not designed by Apple [2]. I fail to see how the details of this are relevant though.

Those SoCs were designed exclusively for Apple products by Apple and Samsung. They were branded Samsung because then Apple failed to notice the importance of brand power of APs.

    Pretty sure they're no longer manufactured by Samsung. It's been TSMC since the A8 [0]. [0] https://en.m.wikipedia.org/wiki/Apple_A8 https://en.m.wikipedia.org/wiki/Apple_A8

      A9 was sourced from both Samsung and TSMC.

  Apple knows this... just doesn't have in-house SoC designers. But they acquire this company: https://en.wikipedia.org/wiki/P.A._Semi https://en.wikipedia.org/wiki/P.A._Semi and team start developing ARM processors.
