What Happens If Apple Switches to Its Own ARM Chips for Macs? (cnn.com) 280

CNN reports that Apple could announce "a long-rumored switch" from Intel chips to its own ARM-based chips for Macs at its WWDC conference Monday -- citing a report from Bloomberg.

Then they consider the possible advantages: When that does happen, the major changes Mac users are likely to see include better battery life and sleeker devices. Apple's in-house chips have a smaller architecture and are more efficient because they are designed for smartphones, according to David McQueen, research director at ABI Research... "Moving to ARM-based chips can bring efficiencies and better battery life without sacrificing performance," McQueen said. "It may also help to cut out some size issues, possibly allowing Macs to be made thinner, while also negating the need for fans," he added.

McQueen says having the same chips running on iPhones, iPads and Macs would also make it easier to standardize the user experience across all three devices. "It will allow all Apple devices to work more seamlessly together," he said. "It should also make it much easier for developers to create apps that are capable of running across Apple devices." There's another big potential benefit to using the same chips for iPhones and Macs, particularly with the growth of 5G networks. "Although Apple has given no indication that it is looking to do so, this switch does also open the doors for Apple to launch MacBooks with cellular connectivity capabilities," Mardikar said.

For Apple, bringing processor production in-house will likely allow the company to offer better performance upgrades with each generation of devices because it will no longer be tied to Intel's upgrade cycle for new chips. "They also get to control their own product launch cadence," said Jitesh Ubrani, a research manager at IDC. "In the past, they had to really wait on Intel to launch new processors before they could refresh the Mac lineup."

  • There's nothing preventing Apple from releasing cellular MacBook hardware now with a bit of USB-attached silicon and some antennas. The fact that they haven't done it yet suggests they're not interested, which is a shame, because it would make tracking down stolen laptops a lot easier.

      That's literately how every other ultrabook works.

      There is a Simcard slot in 100% of Dell Latitude models, but the WWAN card is not present, however the antennas are.

      The thing is, the investors have been pushing for this for over a decade, and it has never happened. Ming-Chi Kuo keeps saying it, and keeps being wrong. So unless he's actually seen ARM Mac's in China, I will wait and see.

      As for if it's to Apple's benefit. It isn't. The only thing Apple gains by switching any device to ARM is longer battery life with better graphical performance, and that device already exists, it's called an iPad Pro. There does not need to be an ARM MacBook. We have already seen there is no appetite for ARM based laptops several times. See Surface RT.

      It has no place on the desktop, and Apple has been scaling the performance down on their laptops which really makes you think that Intel is really just not giving a care and continuing to produce absolutely useless U and Y parts that can barely run Windows, let alone OSX. These things belong in nothing that has a computer screen.

        That's because putting cellular connectivity on a laptop is kinda pointless, virtually everywhere where you're going to use a laptop there's WiFi, so why would anyone pay for a second cellular account and burn data on it? I've had laptops with WWAN connectivity built in and never used it because WiFi is already everywhere. Pretty sure the one I'm typing this on has it too but I haven't even bothered checking.

        Except for the money. Apple is already investing heavily in CPU/GPU development for the iPhone/iPad. If they could use that to create an in-house chip instead of buying from Intel - who is not known for their low margins - they could pocket all that profit themselves. I agree that consumers don't want ARM or any CPU archtecture in particular, what they care about is applications so the key is vendors. WinRT had no commitment and no clear future, it was a niche product by Microsoft to plug a percieved gap in their lineup but there was no indication they'd migrate away from x86 meaning the business case for making an RT version of your software was terrible.

        If Apple does this it'll be with the commitment to migrate at least their whole consumer line of Macs. If you are producing Mac software you can either be there or... not be around much longer. That's a pretty easy boardroom decision. That said, I expect it'll be everything /.ers would hate like locked bootloader, store only apps. But Apple got the financial muscle to make it into a compelling offer for most people anyway. Cue the people saying it'll be totally useless for them, I'm sure that's true I'm just not sure it'll be in numbers that Apple cares about. They've found that professionals run a pretty tight ship of cost/benefit if they want to stay in business while consumers pay based on disposable income. The most profit is in selling bling to people who can afford bling.

          Apple is selling ~90 million iPhones & iPads/year and ~12 million Mac devices (primarily laptops). Use of dedicated classic PC devices is down sharply across all manufacturers and OS'. Once the cutting edge of personal computing the PC is now a small tail dragging being a very large dog.

          • 261 million PCs were shipped in 2019. Which represents a very slight half-a-percent increase from 2018. The PC isn't dying, nor has it been dying. PCs are mature. As far as Apple goes, they have now reached the Ballmer-era stage of their lifecycle: they do what is good for Apple, and you, the consumer, don't fucking matter.

These things belong in nothing that has a computer screen.

        When it comes to performance, it would be asymmetrical.

        Apple's A13 chip from last year in an iPhone configuration was already at level with the best desktops [anandtech.com] in some benchmarks. Of course, this will be more powerful in a desktop/laptop configuration, the chip will be new and improved (A14?) and one can add acceleration for specific tasks, like ML - which you have less of in normal CPUs - some Xeons do [arstechnica.com], but I don't think normal CPUs do.

        That said, I expect running an actual full desktop OS with processes, and multitasking etc will bog the ARM CPUs down - it has been tuned for less complex scenarios for a long time. Comparing to Windows RT makes little sense, unless Apple starts making a "MacOS lite" rather than migrating there. The RT had much less performance, and was always seen as a little side gig which noone cared about. If Apple actually migrates, the situation will be completely different.

        Personally, I hope they don't migrate - for the simple reasons that a lot of existing applications won't make it, there will be even less games if the architecture and library infrastructure changes/disappears (note: I'm talking of high quality desktop games here - not mobile games), and running Parallels/VMware with Windows for those times I need that at work will be a thing of the past. But I'm sure they could offer pretty good performance - I'd expect much better in some cases where special hardware can help, slightly worse in general.

        • Apple's A13 chip from last year in an iPhone configuration was already at level with the best desktops in some benchmarks.

          Be careful how you interpret those benchmarks. A lot of the ones where the Ax processor does well, are ones where it has dedicated hardware to perform a certain function and the desktop processor does not.. Because the Ax is too slow to do the function in software, they had to implement it in hardware to make it usable. Whereas the desktop processor was fast enough to do it in software,

    Apple switching to ARM just means that Apple will have an easier time preventing Hackintosh installations (because inexpensive laptops would then not be suitable hardware platforms; Chromebook hardware probably wont be powerful or spacious enough, and normal laptops will be x86 flavor), Apple's products will cease being able to dual-boot with a useful OS (yes, my prejudice is showing concerning osx. Maybe you could still dualboot a linux, but only if apple does not lock down its boot loader, which if it switches to ARM ISA, it would have more options to do just that.)

    Aside from that, not a whole lot. Apple will ensure that the applications it curates all look and act the same from the end-user perspective, and their almost comical devotion to 1 angstrom thick devices will inch closer to reality.

    • Apple don't care about Hackintoshes. They're not real Macs, they don't get any support and anyone trying to get real work done on one is crazy. Apple are never going to go after a hobbyist building their own Hack, it's not impacting their sales and the publicity would look pretty bad.
      The continued operation of web sites such as https://www.tonymacx86.com/ [tonymacx86.com] with step-by-step guides, boot loaders, drivers and forums is proof of this.

      Apple will bear down with the entirety of their legal might however on anyone selling Hackintoshes as a commercial operation. The mere handful companies who have been stupid enough to try and have a go have all been absolutely crushed.

        Quite right, but that won't be the real reason for locking down the bootloader, should they go that route.

        The real reason would be "iOS integration", and their slavish desires to prevent end users from daring to break their device out of the walled garden. They can completely control the behavior of OSX, and versions of OSX designed to co-exist with an iOS deployment (such as say, with a dockable iPhone and Macbook hybrid) could guarantee that the OSX side cannot tamper with the iOS side to enable such shenannigans-- but would ONLY work if the boot loader was ALSO locked, so that a 3rd party OS could not run (which could then tamper with the iOS data unsupervised.)

        They would of course, call this "Security" (and it would be, in more ways than one-- but the real thing they would be seeking to secure is their reputation and place as the gatekeeper for the iOS application ecosystem, for that sweet sweet licensing 30% scrape of cream off the top.), and ignore any demands from industry apostle groups, like EFF.

        • There's nothing in the current hardware architecture that would stop Apple from locking down macOS like iOS. If they wanted to, they could do it. Just look at macOS Catalina - the entire OS and bundled apps are running on a read-only volume that can not be mounted read/write, even in Single User Mode.
          Running on x86 vs running on ARM has no affect on this, it's an OS-level decision...

          • Again, being able to boot a 3rd party OS would enable a user to circumvent that level of restriction, and perform unsanctioned modifications.

            Thus, need for locked loader.

            • They'll still likely have Target Disk Mode in any new Mac they make, so that is largely irrelevant.
              https://support.apple.com/en-a... [apple.com]

              • Again, that is an OSX OS level feature, and if you can guarantee that a 3rd party OS cannot be booted, you can assure that the iOS partition is never mounted, even when attached in such a fashion.

                In fact, you could assure that the iOS partition is never exposed in any capacity except possibly through an encrypted iTunes level "Restore" capacity as well.

                This is not an argument for negating a want from apple for locked loader.

                • Target Disk Mode is a hardware-level feature, it works irrespective of the OS that's on the machine. In fact, you can boot up a Mac with a completely erased drive and install a new OS onto it via Target Disk Mode.

                  • Yes. So is a locked boot loader. It's a hardware level thing.

                    As stated, that does not need to present the iOS side in any capacity, other than *perhaps* as an iTunes encrypted restoration channel with crypto enforcement.

                    The security hole, is allowing a 3rd party OS to run, pull data out of the TPM to get the device's unique keys, and then write on the protected storage without being sanctioned by apple-- To which, the only plausible fix, is to lock the loader in order to prevent that OS from being run.

                    I am going to be as polite as possible, given this barb you are trying to stick me with.

                    1). The intention with moving to ARM was overtly stated that it would facilitate a more consolidated codebase, between iOS and OSX, since both would essentially be the same hardware platform.

                    2) This leads to obvious synergy to be exploited by further blurring the line between the products, and "Innovating" (in quotes, because obvious evolution is not innovation) to a multipurpose device capable of being either on-demand. (Such as a dockable iPhone that can become a MacBook just by inserting it into an appropriate dock)

                    which then leads to:

                    3) iOS is where Apple makes a killing by controlling the app store, and getting that 30% "off the top" royalty, and is why they rigidly enforce appstore's use on their platform. Once you have a device that is either OSX or iOS on-demand, the former suddenly inherits the latter's need for hard lockdown. Where PREVIOUSLY (eg, where we are right now) the OSX ecosystem had no reason to be secured in this fashion, it now suddenly does, and those features get removed going forward.

                    As for the barb itself that you just leveled--

                    Targeted Disk, is a combination of technologies.

                    1) a hardware level presentation of the volume as an external media device.

                    2) OSX recognition of this external media device, by the operating system and installer software running on a different system that the target gets connected to.

                    The first is hardware level, the second is OSX OS feature level.

                    Jumping the shark like you did, and presuming I am some kind of idiot, is off the mark and wrong.

                    Thank you, and good day sir.

                      It has to do with the software running on the host you plug that target into, to affect that target. In most cases, this is going to be MacOS, and it will be the OS installer app. (which are both going to be using OS level features to do that detection and determination.)

                      The hardware level portion can easily just ignore the first #foo number of sectors on the physical volume, and present a new logical LBA 0 starting point. In other words, it can completely fail to allow access to the iOS portion of the device.

                      Sure, they could implement a logical start sector in order to protect that hypothetical iOS partition that you just pulled out of your ass. You don't know yet whether the hardware is going to implement logical sector addressing, or whether there's going to be an iOS partition on newer Macs, or whether the hardware is going to forbid you to touch that partition... Yet here you are presenting those hypothetical scenarios and criticizing Apple for what they COULD do if your predictions happen to become true.

This is the core OS, the Apple-supplied apps like Safari, Mail etc and the preferences used by many core system services.

    Changing the CPU architecture from x86 to ARM won't change the user experience. That's all software, all of which runs just as well regardless of the underlying CPU hardware. It's been a long, long time since we did anything involving the UI using assembly language, it's all high-level languages which are pretty much independent of the CPU architecture. Ditto for cellular connectivity, that's also independent of the CPU as the hardware connections are through buses outside of the CPU. The only possible way a switch to ARM might affect cellular connectivity is by having chips that already incorporate the cellular chipset into the main CPU chip available for immediate use. No, any switch to ARM is going to be invisible to users aside from improvements in battery life and size due to a simpler architecture having a lower power demand and generating less heat. The big impact will be on the companies that make software for the Mac who will have to recompile their software for ARM rather than x86 (which shouldn't be a major problem if they've designed their software anywhere near sanely).

    The performance gap between mobile and desktop shrinks constantly. Apple can port macOS to the iPhone and seamlessly switch to it when it is plugged in a docking station. Unplug it and switch immediately back to iOS. Storage can be shared and it can even keep browser sessions and apps which have versions for both OSes persistent when switching.

      If anything, the performance gap between mobile and desktop is growing, not shrinking. Reduction in power consumption has allowed massive increases to desktop CPU capability (which were temperature-constrained, not power-constrained), like AMD's 64-core Threadripper 3990X.

      What's going on is computer hardware performance is increasing faster than user requirements. It used to be that to run a decent graphical app, you needed a workstation-class computer. In the late 1980s/early 1990s, desktop PCs got fast enough to handle what were formerly workstation loads. In the 2000s, laptops became fast enough, and end users began switching from desktops to laptops for their everyday computing. And in the 2010s, mobile devices became fast enough to handle most people's everyday computing, leading to some giving up their laptops (or in Apple's case, planning to switch their laptops to mobile SoCs).

      But if you need the extra oomph, a desktop or workstation-class computer is still where it's at. If it weren't, animation studios would be using laptops or mobile devices for their render farms.

  • Seems out of character that they would release a chip that strictly follows ARM .. I think at minimum they would add their own extensions, if not now .. soon. At max, it'll be a whole new incompatible instruction set architecture. Why wouldn't they ditch both ARM and Intel? They have absolutely nothing to gain from being ARM compatible. They have a CPU architecture team. What do they need ARM for?

They were still not considered good enough for the iPhone whenit was released -- which is why it got ARM chips initially, and thus the ARM ISA. Apparently they improved. And now they are supposedly good en

With all cores running at full speed. The iPhone slowed down after a while, probably due to heat, but was _still_ faster.
