M1X vs M2 Macs — Differences Explained!
, I’m, Rene Ritchie., Welcome to the channel. And today we’re talking about M1X versus M2., The next extension versus the next generation of Apple Silicon for the Mac and why there seems To be just so much confusion and misinformation, swirling around it., So yeah grab a beverage, maybe a snack, because we’re gon na get just super nerdy with this. Sponsored by Brilliant.. We are so close so close to a quarter million. So hit that subscribe button and bell. So we can build the best community in tech, together. Nikkei pushed out a piece on the M2 and Bloomberg previously reported on what we’re, just colloquially, calling the M1X.. Basically, the chip sets that all of us nerds are waiting to run on all of the higher end. Macbook Pros Mac mini iMacs, eventually the Mac Pro the redesigned, MacBook Air., Just all the Macs that we’ve been waiting for clamoring for, but these names, M2 and M1X are being thrown around almost Willy nilly., And so I think, it’d be super useful, really a convenience to Just clarify what those terms actually mean. Now, historically speaking, there are two ways that Apple has iterated on their Silicon.. The first is by generation. A11 A12.. The numbers go up. For generations; they just get higher.. The other is X tension, A12X. A12Z letters get added to them.. The names get wider. Generations are architectural generations like IP generations. Apple has been incrementing those every year on the year for years, for, like 11 years now.
With things like custom, CPUs, custom, GPUs, neural engines, machine learning, accelerators by moving to seven nanometers, then five nanometer Processes. Moving to 64 bits and ARMv8 instruction set architecture or iSAW those sorts of things., The first generation was the A4 introduced in 2010 with the original iPad and then the iPhone four. And that’s. Why we’re? Currently, on the 11th generation., The A14 Bionic introduced in 2020 with the iPad Air and the iPhone 12., But also with the M1 introduced just a month later, with the first round of Apple Silicon, Macs, the MacBook Air, the two port MacBook Pro the newly re silvered Mac mini and now the fruit flavored, and by that I mean colored entry level iMacs., And that brings us to those extensions.. The feature. Extensions Apple started that with the A5X for the first retina iPad in 2012. And they’ve typically done it by increasing the number of compute engines, adding extra CPU and GPU cores also increasing the memory bandwidth. That sort of thing., But, unlike the generations, Apple hasn’t done. These extensions, every year. And certainly not on the year there was no A7X or A11X or A13X, and there hasn’t been an A14X. Well technically, there has but Apple branded it. The M1 and that’s because it’s the same Silicon generation and architecture as the A14. Same CPU and GPU cores.. It just has two additional high performance cores and four additional graphics cores. Just like the A12X was the same generation and architecture as the A12.
Just with two additional high performance cores and four additional GPU cores., Even if all of those GPU cores aren’t always fully operational., Now Apple, also extended the M1, with a couple of Thunderbolt controllers on package and some extra IP for hypervisor and X86 translation. And yes, a lot more memory., Eight gigabytes or 16 gigabytes. More RAM than any Apple Silicon chips that it ever offered before it., But otherwise. It’S the exact same playbook that Apple’s been executing on for years. Higher generations from A12 to A13 to A14 and wider feature sets from A12 to A12X and A12Z and from A14 to M1., Far fewer cores, far lower power draw for the tiny thermal envelopes, like the Iphone and many more cores higher power draw for bigger thermal envelopes like the iPad Pro and the Mac.. But what does it mean for what will be for an M1X or M2? Well, if Apple sticks to pattern – and, of course, Apple always sticks to pattern up until the very moment that they don’t, but if Apple sticks to pattern on this M1X would be a further extension of the current 11th generation system on a chip architecture.. A further extension of the M1. So instead of eight CPU and eight GPU cores it could have 12 or 16, maybe even 32 or 64 or conceivably even more. At some point you know, Along with like 32 gigabytes or 64 gigabytes of RAM four or more Thunderbolt controllers, all of those extra amenities.
. Now that does mean that single core performance would Probably be similar, if not the same. – And I only say probably because Apple could always play with the frequencies on those higher end. Machines., The ultra low power ones, maybe sacrifice some frequency for a good amount of battery life efficiency, but the higher end ones might have more bigger batteries or just be willing to prioritize frequency, but otherwise, yes, core for core the same. Just way more cores. Way way. More cores. And M2 well M2 would be the next generation of Apple Silicon, the 12th generation right alongside the A15 that we’re all expecting to launch, along with the iPhone 12S, this fall and with it we’ll, probably see the same kind of single core improvements. We’Ve been seeing over the last many years about like 20 for the CPU. More for the GPU. If Apple keeps pushing really really aggressively on them. And that might come from things like process improvements going from TSMC’s five nanometer to 5P., Maybe if they adopt or get anything out of the new ARMv9 instruction set and then whatever architectural optimizations and improvements. That Apple is already working on already has on their roadmaps this stuff that’s, given them those single core boosts year over year for lo these many years already. And could Apple change things up and call the M1X the M2, Maybe because it might sound better in marketing. For the higher end, Macs. And yes, sure again, Apple sticks to patterns until they don’t, but I think that would be hugely problematic.
. It would burn through the numbers way faster and it would muddle up the generations and make things just more confusing for people like me who pay attention to Apple Silicon, just at a deeper level. And then what would Apple call the actual next generation chip sets. What would they put in the next generation redesigned? Macbook Air? I mean Apple used, the M1 branding for the iPad Pro, not the A14X branding., So sure. Never say never, but I will say: can you not In terms of the win, I mean we could get the M1X anytime. And for me, the sooner the absolute better, because I need that 16 inch, MacBook Pro and iMac Pro in my life, like immediately. And with WWC kicking off on June 7th. I have hopes and dreams that they’ll just be folded right into that keynote. For the M2. I think the best that we can do is look at past behavior and just extrapolate that for future behavior.. So the M1 came out right after the A14 that it was based on last fall.. So we could conceivably get the M2 right after the A15 that it’ll presumably be based on this fall. And that’s. What Apple did with the A12 and the A12X in 2018 as well., But, like I said Apple, sometimes does wait. Longer. Sometimes even skips entire generations. For the extended versions., All this to say, even if Apple keeps pushing out new generations of A series chips for the iPhone every year like they have been for the last 11 years, there’s no guarantee they’ll make M versions for each of those generations.
I mean I Would absolutely love it if they would, but this is a whole new game and we just have to wait and see how Apple plays it.
