Apple Plans To Announce Move To Its Own Mac Chips at WWDC (bloomberg.com) 217

Apple is preparing to announce a shift to its own main processors in Mac computers, replacing chips from Intel, as early as this month at its annual developer conference, Bloomberg reported Tuesday, citing people familiar with the plans. From the report: The company is holding WWDC the week of June 22. Unveiling the initiative, codenamed Kalamata, at the event would give outside developers time to adjust before new Macs roll out in 2021, the people said. Since the hardware transition is still months away, the timing of the announcement could change, they added, while asking not to be identified discussing private plans. The new processors will be based on the same technology used in Apple-designed iPhone and iPad chips. However, future Macs will still run the macOS operating system rather than the iOS software on mobile devices from the company. Bloomberg News reported on Apple's effort to move away from Intel earlier this year, and in 2018.

      It was never what they wanted. When everyone else was on 32-bit x86, they were on m68k and PowerPC. Their Intel time is relatively short compared to their whole history.

      To be honest, though, it's what really grew their ecosystem.

      Nah, do not fret about it.

      You will have parallels, VMware, VirtualBox and Bootcamp. It just so happens that those will run ARM versions of Windows and Linux.

      • Which won't run apps compiled for x86 / x64 architectures which is the whole point of using them for most people who use it.

        Not to mention WINE. I use WINE on macOS too, again for running apps compiled for x86 / x64 architectures.

        • Windows 10 on Arm runs x86 software without modification.

          Ever hear of JIT compiling? Windows 10 Arm automagically JIT recompiles x86 software on first-run. Then it runs the (now native Arm) version.

          x64 support is not there quite yet; but is expected to be previewed sometime in 2020, with an actual rollout in 2021.

      • You probably won't be running VMware or VirtualBox . I don't believe ARM chips support Virtualization. The ARM version of Windows is useless at this point. ARM Linux works pretty well, but again not running in virtualization software. I guess Apple could put two A1X chips in their Macs..... One for the OS and one to support Debugging. At this point it looks my Trusty old 2015 i7 macbook Air might be my last.

          I think x86 just has issues with virtualization that require extensions to work around because it is CISC core. ARM being RISC should be able to work in a hypervisor without having to keep track of the pipeline, thus no extensions for virtualization should be needed. Though I'm not a hardware expert, so don't quote me on that.

          • Correct, and that was with the benefit of a considerably faster host CPU which would not be the case with ARM.

            Excuse me, but ARM chips are bloody fast. And if you build something with LLVM, you can probably directly compile x86 to ARM.

            • Nobody uses a VM to run an application that was compiled with LLVM, though. They use it to run an application that was compiled with Visual Studio 2008.
      • MAME emulates hardware that's 2-4 decades old, sometimes barely. I don't think many people are interested in running modern Windows apps in an emulator running at the speed of a 300 MHz Pentium II. It's not a question of market demand. It's a question of what the new Mac CPU is (not) capable of.
      • MAME works well because the hardware it runs on is significantly more powerful than the hardware it is emulating, so it can afford to be inefficient relative to native code execution.

        Unless the new ARM hardware is significantly (eg 10x) faster than the current Intel chips Mac uses, MAME-style emulation is going to be slow.

    To me this seems like a mistake, but who knows. Some of the appeal of Intel-based Macs were that you could play in the Apple ecosystem without being 100% silo'd in it - you could use a Mac to dev for Apple desktop/mobile while also using it to dev for Linux/Windows at the same time (with varying degrees of hoops to jump through). There were a few years there where I used a Mac even though all of our code was running on Linux, but I could still run it locally.

    Don't know how much of that will go away or become harder with this, but I'd be much more wary about using Macs as dev machines anymore, unless I was at an Apple-only shop.

      My guess would be that they will start with some low end models, maybe a refresh of the Air because currently it's a very compelling alternative to the MacBook 13".

      They will have some key apps ready day 1 and wait until more get ported. Some kind of x86 emulation layer for "legacy" stuff but performance will suck.

          They aren't going to stick an entire high end Intel core on there so whatever compatibility features it has won't be in the same league performance-wise.

          Then again Intel isn't all that great any more, AMD's Ryzen 4000 mobile CPUs are superior.

          • by dfghjk ( 711126 )

            You don't add an entire core, you add an instruction decoder, and your comment assumes that "same league" performance would be the target of such a thing. It wouldn't.

            • by AmiMoJo ( 196126 )

              That's the thing with x86, the instruction decoder on its own is only a small part and not that critical to performance. Most of the performance comes from stuff further down the pipeline.

              You might as well just do dynamic recompilation in software with a bit of caching.

            • by Megol ( 3135005 )

              Adding a decoder wouldn't help much as x86 and ARM differs in several critical parts and an x86 decoder is quite complex already with an x86 execution back end.
              Software translation is a better choice - no or little extra hardware, no complications in critical execution paths, no overhead running native software.

          Remember Transmeta Crusoe? It was designed to do that, still failed.

      • My guess is the exact opposite: they'll start with the Mac Pro. It's a low volume system, it requires the least retooling (just a new motherboard), and most of the apps that people rely on are made by Apple itself (i.e., Final Cut Pro and Logic, and to an extent, XCode). It also gives the most room for yield problems, because they don't need so many chips and it won't become a bottleneck if there are troubles. Mac Pro customers are also the least price sensitive.

          I think that models that have the âoeProâ designation will either remain Intel for quite some time; or will add an Arm coprocessor.

          Appleâ(TM)s Arm chips for this will not be the familiar Ax-series SoCs. They will be far more performant.

The laptops benefit because Intel hasn't been able to deliver on lower power chips for some time. The Mac Pro benefits from actual movement in the high-end, high-core-count space, where the Xeon has been stuck and iterating slowly for years. All the stagnation is at the highest and the lowest ends of the spectrum.

            This. They have long experience in supporting two architectures at the same time: 68K+PPC, PPC+x86, x86+x64, now that they've just killed 32-bit x86, there's room for ARM-64. Not that they couldn't support three architectures in the OS, but they probably don't want the waste of a triple-architecture OS install, nor the load delay of the OS itself using JIT-linked clang object files.

      Likewise. Most of our software development company is using Mac laptops today, with only a handful of people on Windows-only projects still using older Windows PCs as their primary machines. We do development for Windows, Linux, iOS, Android, and Mac, roughly in that order of frequency, so Mac laptops with Windows and Linux VMs have served us well, but we go where our clients want us to go and make sure we have the best tools for the job, so if those tools become worse for the work we're doing, we won't hesitate to use other tools. While individuals at the company may have preferences, the company as a whole is fairly platform agnostic, so I doubt very much that we'd demonstrate any sort of loyalty towards Apple if our way of working is no longer supported.

      That said, I use Macs at home, and for home use I'm very much looking forward to this. Usually you can only pick two of the three in cheaper, better, faster, but Apple has managed to pull off all three. Their performance gains with the A-series chips these last few years have been incredible and are easily outpacing Intel's gains. Rather than simply keeping up with Intel, they're eclipsing higher and higher performance chips from Intel each year in both single and multi-threaded benchmarks, while simultaneously costing less, using less power, and producing less heat. For home use, where I expect everything I use to continue working largely without issue, this is a win all around.

          Per-thread, Intel chips are faster, MHz for MHz, than AMD's. Not by much, but it's there. AMD's are faster overall because you get nearly twice the cores for the money.

          Per-thread, Apple's A-chips are faster at most common operations, MHz for MHz, than Intel's. You get Intel running faster in specific cases where instruction set extensions speed things up - TSX for databases, for example. But for most common use cases, the A series is faster.

          There isn't anything really stopping Apple from throwing a dozen high-speed cores in an A-series, except that they are meant for tablet and phone use, and don't make much sense there. For laptops or desktops, however...

          As for GPUs, AFAIK there aren't any inherent roadblocks for Apple to hook an ARM up to an AMD or nVidia GPU. nVidia makes their own ARM chips using their own GPUs, so it's certainly feasible on that side.

    I was wondering who would be the first to do this. Lately people have just sort of taken it as a given that desktops and workstations should use scaled down versions of server processors, but as mobel tech takes on more and more of the tasks that used to be the exclusive domain of PCs, it makes sense to at least try scaling those processors up instead. This esp makes sense for Apple since it means they can unify around a single architecture across multiple product lines.

    And personally, I think it is nice to see some competition in consumer CPUs again. x86 has been the only realistic option for a while now, but those chips have so much historical baggage and have to support so many use cases, I'm kinda excited about seeing some sort of clean break, and ARM is in a really good position to deliver such a thing.
