A 5nm, a14 or a15 based MacPro is suicide for the MacPro.

The W series Xeons in the current Mac Pro are fabbed at 14nm and it is evidently one of Apple's better-selling current Mac families per a recent 9to5Mac article... :eek:

An M2 family SoC at 5nm is going to be significantly more power and thermal-efficient so I fail to see how it would be "suicidal" to move the model to it...

A 5nm, a14 or a15 based MacPro is suicide for the MacPro. But realistically, there’s not going to be an Apple silicon MacPro. The volume is musicale, and the hardware expectations are a galaxy away from what the M series can deliver. It’s just smarter to let that line finally die. Either that or we get a Max Studio with a couple non-gpu PCIe slots for $6k and up, and I think we can all agree just letting the name die is better than that.

It’s not about matching with AMD or intel, it’s about spending a lot of money and effort to be the launch customer for 3nm and then letting someone else get 3nm into computers first. The 5nm roll out may have been slow, but AMD only got to 5nm in late 2022, a year after the M1pro. Meanwhile, AMD’s roadmap still calls for 3nm Zen5 and Zen5c to launch during 2024. Apple should be concerned about zen 5, since laptop zen 4 is already nipping at m1pro’s perf/watt when in low power modes. If AMD gets a node advantage, Apple will lose their Perf/watt advantage, and I don’t see them willing to do that.

Also, realistically, even 1 million m3max dies likely takes less than 10k wafers (assuming the die is even larger than the M1 Max despite the denser node). Meanwhile TSMC was making almost 100k 5nm wafers per month by the end of 2020. Assuming a similar ramp up, the entire first quarter of MBP sales can be produced from 3 days worth of wafers. That’s inconsequential to iPhone production, especially since Apple can easily launch non-pro phones with the a16 to help yields for the a17.

But we can speculate all day. My main point is that there seems to be only a vanishingly small chance that an m2pro ever launches. The hardware and designs in the a15/m2 are far too out of date and the vastly better a17 and n3 node too close to release to make an m2pro feasible. Even if we get a winter/spring MBP on n5P or n4, it has to be based on a16 and therefore would still be named m3 pro not m2 pro. If the M2pro ever existed (and I don’t think it did, I always assumed the bigger, low volume dies would skips generations), it doesn’t now. Or we’d already have seen it.
That’s a lot of big words to say apples going to switch everything to 3 nm in six months.
NOT GOING TO HAPPEN!
To start with, again, Apple does not care about having the first 3 nm computers on the market.
It won’t affect their bottom line, and they still make products to this day still based off of 7NM.
As for the speculation that Apple might discontinue the Mac Pro, it’s nonsense. They’ve already officially announced an Apple Silicon Mac Pro “in name” is coming.
They announce that at the same event as the original Mac Studio.
Even if it’s not the Mac Pro *you* want, it’s still a Mac pro.
And again, Apple is not introducing processors, they are introducing products.
They don’t have to compete with AMD or Intel or have their processors out first, because they know most of their customers will not care.
The A12Z iPad Pro and the M2 Air prove this, both were introduced right before a new architecture went into production, Apple still released them anyway, and they still sold like hotcakes.
People aren’t going to switch to a PC just because Apple didn’t release 3 nm when they liked.
All the rumors from very reliable sources, and even leaked benchmarks all point to new MacBook pros on the 5 nm process, and the same is likely true with the Mac Pro.
These are my expectations, backed up by Apple’s previous scheduling and reliable sources.
Again, Apple couldn’t care less about how fast they come out with chips compared to the competition. If they did, they wouldn’t still be selling almost an entire desktop lime powered by M1.

because releasing your “highest end” $6k+ machine that has last seen updates in 2009, 2013 and 2019, so will likely remain unchanged until nearly 2030, powered by a glorified iPhone SoC from 2021 is worse than just not releasing it.

It’s not really about the node, but the nature of the “overgrown outdated mobile SoC as Mac SoC” design theory speeding head first into the brick wall of competition like 96 core zen 4 Epyc and soon Threadripper chips. Nothing Apple can design around the a15/M2 core and unified SoC architecture can compete with that.

And anything that can compete, which would be like a 8small/120 big core CPU with 12+ channel user upgradeable DDR5, at least 64 PCIe lanes, and some sort of upgradeable GPU solution that offers at least 128 of the upcoming ray tracing capable GPU cores, would require so much new R&D for such a niche product —there’s no way apple sells many MacPros. Even if there was demand (there’s no demand for a decent $4000 workstation from 2019 when it’s being sold at $6000 in 2023) — that it will never happen.

My personal opinion is there will never be an M2Pro or an Apple silicon Mac Pro. Most jobs a Mac Pro used to do can either be done on a MacBook or have been offloaded to render farms/data centers. The “personal workstation” is mostly dead, and Apple has no real reason to pretend it’s not by selling a new MacPro.

Not everything. The a17 and m3pro will hopefully be on 3nm this year. And Apple does care about the perf/watt numbers. Mobile zen5 WILL beat m2 in that metric. M1 was 2-3 years ahead of AMD (intel is still lost in the woods) in this metric when it came out, but it’s now over 2 years old and has a pretty small perf/watt advantage over the zen4 7900 desktop chip.

But again, none of that is relevant. The M2pro doesn’t exist because the a15 and m2 have been in production forever, and the 14”/16” and mac studio have been in production forever. IF apple wanted to put out an a15 based M2 pro MacBook Pro, they would have already. The only possible reason for the “delay” (again, there’s no way the MBP wasn’t intended to have an 18-24 month lifecycle), they would have done so already. Simple as that.

Apple also confirmed Air Power and a 2 year transition to Apple Silicon. Plus “more great intel MacS to come” when only one minor iMac update was still in the pipeline. Just because they thought they’d trot out an embarrassing “MacPro” as of early 2022 doesn’t mean they will. They should not release a Mac Pro until they have answers for things like 96core Threadripper/Epyc CPUs with massive PCIe bandwidth and the GPU options that brings. That’s something the monolithic SoC design will never match. Even a “48 core CPU/160 core GPU” “M2 ultra Max Supreme,” with 64+ PCIe lanes would barely suffice for a midrange Mac Pro. And even that would be limited by lack of GPU support, 256 or 384 GB of soldered RAM, and Apples ridiculous built in/soldered SSDs.

Apple just isn’t set up to build a workstation type machine anymore, and that’s ok. Let’s just stop pretending they’re about to completely change on this front.

The Mac Pro doesn't have soldered SSDs and I have doubts about the gossip that the memory won't be expandable.

Silicon Graphics were the first company to have Unified Memory Architecture and they had no problem including memory slots.

Nothing Apple can design around the a15/M2 core and unified SoC architecture can compete with that.

Apple has zero interest in HPC so they're never going to offer a CPU with anywhere near the cores of the Intel Platinum and AMD Epyc 9600 families, much less in multi-CPU configurations of such. So even if Apple is the first company to adopt 3 picometer fabbed CPUs, they're not going to put 100+ cores on it because that doesn't appear to matter to macOS users.

What does appear to matter to macOS users is productivity application performance and thermal/power efficiency and right now, Apple Silicon is untouchable in those areas.


My personal opinion is there will never be an M2Pro or an Apple silicon Mac Pro. Most jobs a Mac Pro used to do can either be done on a MacBook or have been offloaded to render farms/data centers. The “personal workstation” is mostly dead, and Apple has no real reason to pretend it’s not by selling a new MacPro.

The only real advantage I see in a Mac Pro class workstation is internal PCIe expansion for the smallish market segment that needs it. And that seems to be what Apple is now planning - a model with Mac Studio performance coupled with PCIe slots.

you can believe what you want until the cows come home, but Joswiak said not even a full year ago that an Apple Silicon Mac Pro is coming.
I’m gonna believe him before I believe the guy who thinks Apple’s gonna come out with an M3pro before a basic M3.
Also, AirPower was a disaster. That shouldn’t have happened, it was embarrassing, but it is absolutely not Apple’s norm.
In the entire post iMac Apple, the only things I can remember being announced and then canceled before release were some high-end G5 configurations in the early 2000s, AirPower and the on device photo scanning.
An M2ultra in a MacPro is none of these things, absolutely no reason to believe it will never come out.
Top executives at the company have literally mentioned by name and sent that they still plan on releasing it, you can’t get much more official than that.

I’m fully aware that there’s no need to have soldered RAM, but we’re talking about Apple in the 2020s. They won’t release a machine without soldered RAM and SSD because that would be leaving money on the table and they’ll never do that

Don’t hold your breath. It would cost more than the rest of the Mac line’s R&D budget to develop all the custom chips needed to make a Mac Pro feasible. It’s not gonna happen.

We may get a Mac Studio with some tiny extra feature, and they may even call it “Mac Pro”, but we’re not getting a Mac Pro. And I severely doubt we even get the Mac Pro in name only at this point.

Why the heck is it surprising that the high end part (m3pro) would come out first? That’s very common in chip design, and wouldn’t be weird. Got marketing, it’s a lot better to say “the new iPhone has the heart of the MacBook Pro” than “the new MacBook Pro is a couple iPhones taped together”

Apple Silicon isn’t untouchable. It’s currently a couple percentage points better in perf/watt when compared to same node competition. Every Mac Pro has been HPC class, a new Mac Pro also needs to be.

If they give up node advantage, they will give up perf/watt and thermal and battery advantage. High quality Zen5 (3nm) laptops next year will be better than m1 and m2 in these categories, without 3nm Macs will fall behind. These are facts of physics.

The studio with PCIe, should be called that, or maybe “Mac Studio Max,” but it sure as hell ain’t a Mac Pro if it can’t support RAM into the Terabytes.

The 4090 doesn't have ridiculous power requirements. It's actually at least 56% more efficient than the 3090. Nvidia overengineered/oversized the cooling solution because they thought the AD102 would run way hotter and use way more power but it didn't. With a little voltage adjustment the 4090 instantly drops 50w in power usage without affecting the performance. I mean seriously, the internet is full of reviews and deep dives in AD102's, AD103's architecture characteristics, it's funny how much users on this site live in a bubble but want to give opinion about different hardware and chips.
And it's true, the M1 Ultra's GPU isn't competition for the 4090 in any way as the 4090 is in a different universe in terms of performance.
You’re living in a bubble by omitting the 4090’s faulty cable design.

The 3090 can draw around 350W. The 4090FE can draw 450W. The over clocked models may draw over 600W. Soon it will need a PSU for its exclusive use. Comparing a 4090 to anything Apple is producing is ridiculous.

If it's just a spec bump and these 3nm chips are already in mass production... I don't get it. And I especially don't get it if the M2 Pro/Max just end up being plain ol' 5nm

This is EXACTLY what I’ve been saying! Give me 3nm and/or M3 chips in a current ‘Pro’ device

No way they would be ready for this lineup. It would have been delayed until Summer/Fall and they can't wait that long for a refresh. Currently, it is looking like it will be a year or more before 3nm for the Mac. They didn't even get 4nm this round, never mind 3nm.

Edit: Also, prices would increase with 4nm and even more for 3nm. It appears Apple is trying to stay away from that for the Mac for this round.
