correct me if I'm wrong, but isn't the reason they moved to Intel chips in the first place because their homegrown CPUs couldn't keep up? Has that calculus changed in the meantime?

PowerPC wasn’t really homegrown.

  Though Apple was part of the original PowerPC consortium, and back then also had a chip team. Then again Apple was also the other partner (with Acorn) in founding ARM.

They switched because Freescale and IBM couldn’t keep up with Intel. Apple did not make CPUs at that time. https://en.m.wikipedia.org/wiki/Apple%27s_transition_to_Intel_processors https://en.m.wikipedia.org/wiki/Apple%27s_transition_to_Inte...

  Fair enough, I always associated PowerPC with Apple and assumed they were the driving force behind it's use. Regardless, that makes the financial calculus even more suspect as they would have even fewer units to amortize the cost over. But I don't work for Apple, and quite frankly the CPU market could certain use the injection of some more competition.

    They helped a little with the overarching design (the ISA of the vector unit was pretty much Apple designed) but they never made any chips themselves AFAIK.

    Fewer units? They have arm processors in every iPhone, iPad and AppleTV. At least 70 million units a quarter. The Mac CPUs would need more cores/threads (perhaps octocore).

    Apple and assumed they were the driving force behind it's use Quite the opposite. Apple, according to the book The Race for a New Game Machine, was an unprofitable demanding customer. The scale of the XBox 360 and PS3 dwarfed Apple's usage and IBM made several decisions that were contrary to Apple's needs. PowerPC for the embedded market has been the primary driver of PowerPC development.

      At some point IBM offered Apple the Cell processor. I'm glad Apple opted to move to Intel then. The Cell is the hardest thing I ever tried to write code for.
      - protomyth 7y ago
        IBM made decisions about the Cell PowerPC that made it unsuitable for Apple (no out of order) and offered the 970 as compensation. We all got to see how those promises played out.

I think a lot has changed. Maybe not the ability to consistently lead Intel, but at least a larger portion of end users that would find an ARM laptop "good enough" exists now.

  AMD is beating intel on price and performance and they have a fraction of the resources of Apple. Intel is behind on process and has been for a couple of generations right as everyone hits a process wall. For the first time since I got into computers in the late 80s Intel looks vulnerable. As to whether Apple would go ARM on a MacBook who knows, I’d guess they wouldn’t but they could straight buy AMD in cash so it’s not beyond the realm they could tool up for desktop class ARM.
  - bshipp 7y ago
    Indeed, AMD is finally in a good position after years wandering the desert. That said, this current strong performance is the result of years of R&D, something that would have to be built from the ground up if Apple was to try and replicate it. I can't help but think there must be some secret benefit to make them pursue such a risky endeavour for something so tangential to their comparative advantage. Apple doesn't sell custom components, they sell consumer experiences. They must be planning on going a completely different direction with iOS to warrant custom processor technology.

      I suppose hiring people like this (and this is he one we hear about they could have hired 20-30 people without anyone noticing) is a way to shortcut such R&D
    - IOT_Apprentice 7y ago
      Umm, you do realize that Apple has a large design team and outsources Fab to TSMC? Their iPhone/iPAD/AppleTV hardware platforms already run on their own ARM chip design. They SHIP over 70 MILLION units a quarter. They have the R&D teams already churning out new designs each year. How is this risky?
