Gurman published article this morning with some new info on Macbook 16, before Apple's announcement. At the end of it he mentioned that Apple still working on ARM Macbook to be released in 2020.
A doubled-up iPad processor would clearly outperform any Intel processor and be much cheaper and energy/battery efficient.
I think we’ve all very fairly assumed that an ARM MB/MBA would run MacOS, but what are the chances of Apple launching an ARM-based MB/MBA running iOS?
That's much too expensive, nobody outside of some special applications hand-tunes their code anymore. "Optimized for" is, more often than not, just empty marketing speak.Applications have gone through years, if not decades of hand tuning for x86, whether it's SSE2 or the memory architecture.
Outside of HPC and some specialised multi-media libraries and similar? Too expensive.Is hand-tuning in-line assembly still a thing these days?
That's the only practical way Apple's Pro line is likely to move IMO.To be honest, I would like a Mac with a dedicated ARM chip like A12X and an Intel CPU as well, just like we have dual GPU (integrated and dedicated in MacBook Pro.) I know the OS will need to be rewritten, but there may be a solution to this.
Excatly, I would be nice to have an ARM co-processor taking over, when during simple stuff like writing documents, mail, watching videos and browsing. With a 99,8 battery and ARM processor one could get an enormous battery life when using this ARM processorThat's the only practical way Apple's Pro line is likely to move IMO.
And in some ways, we already have that: The T2 is essentially a variant of the A10.
What I see happening on that front, would be Apple's ARM "coprocessor" taking on more tasks over time. Possibly the option for Apps to bundle an extension built for ARM to offload some tasks, or possibly even to allow the Arm binary to run in the background while the main x86-64 binary is not running - e.g. a Mail or messaging or VOIP client could have a small "listener" binary that runs on the low power ARM chip (saving battery life on a laptop) and triggers either a notification, or even opens the main binary upon some event (e.g. an incoming call).
They aren't going to build an ARM chip that idles lower than 1.3W by a meaningful amount, they aren't going to build one that's enough faster to make up for the effects of emulation (and some software will be emulated unless they are willing to LOSE a lot of software either to just plain not existing or to getting iPad versions instead of the full ones).
Microsoft is running emulated Office on their own Surface Pro X!!!! MS is not going to port Office to ARM on Mac when they can't even get their act together on their own OS - they'll either Catalyst Office for iPad or let Office for Intel Mac run emulated!
I'm skeptical about Arm Mac also, and agree with what you say. But it's Apple, and going ARM gives Apple one good advantage. They can market their Mac detached from easily comparable PC x64 chip generations. They don't have to stick with annual update like now where Apple's constantly under pressure when a new generation of CPU chip is available in market. Going ARM will make Apple easier to market their computer as like generation less and "good enough" Mac for a longer period thus by maximizing their profit. It's evil approach, and I don't have confidence enough in Apple to believe they won't do it.Yep. Which is why ARM-based "pro" MacOS computers are a pipe dream, perpetuated by forum nerds. I honestly don't understand why so many people are on this bandwagon, when it makes so little sense to Apple and MacOS users.
The only semi-plausible reason for ARM Macs that I've heard is cost savings on A-series chips versus what Intel chargers for their CPUs. I don't think that's significant enough for Apple to make this leap, which will otherwise do nothing but cause pain to the end users.
What we will likely see iPadOS evolve and expand into new form factors, like dual-screen clamshells. That's is going to be the future of Apple's investments.
However, MacOS and Mac product line is going to remain right where it is - Intel x86 based OS with some peripheral functions aided by ARM co-provcessors (such as T2 chip and its successors). ARM MacBook Pro (in a classical sense) won't be happening.
We can see how awful of an idea it is with how the ARM powered Windows Surface laptop. You'd have to emulate any program not natively designed for ARM, and that would come with a massive performance drop.
? do you honestly think they’d do that? That they would replace the current Pro with something that performs like the ARM surface laptop? Really? I’m not hugely optimistic, but I’m reasonably certain that they can mitigate the majority of these concerns in the majority of circumstances.
Well quite apart from the doom mongers I'm eager to see what Apple can do with their own chips in this space. They've got impressive performance out of their phone and tablet chips, let's see what they can achieve in a laptop form factor. I'm not worried about app support, iOS is a much more active developer ecosystem so even in the unlikely event Apple says jump and some developers don't, new alternatives to their products will no doubt be forthcoming soon after.
Mitigate those concerns how? Even if Apple re-wrote all of the in-house MacOS apps for ARM (not likely) - do you seriously expect Microsoft and Adobe re-writing Office and Creative Suite? Microsoft can't even port Office to their own Windows for ARM. And I am not even talking about smaller developers - they barely support x86 MacOS and iPadOS as it is. Twitter won't even release a MacOS app, until that Catalyst junk came along. What makes you think those devs are going to support yet another proprietary desktop OS by Apple? They won't.
And short of native ARM apps - there is no getting around an emulation layer, which is going to be the same garbage user experience as Surface. You can't just hand wave these issues away - "oh it's Apple, they will figure something out". They won't, and hopefully they are smart enough to not go down this rathole.
They won't, and hopefully they are smart enough to not go down this rathole.
