okay, serious question....the PCIe slots are for what? I understand as a non-professional that there are things I would be missing, but it has 2x 10GB networking already, seemingly enough I/O for as many random devices most people would want to plug in. This probably doesn't support the add-on cards that were sold for the Intel-based devices and I have to guess companies that need more niche things are running Windows/Linux/etc. anyway.

Not trying to sound annoying, I just actually want to learn what use cases this could fill.
 
Plus USB-C is over 9 years old, and the power grid it requires… you don’t even wanna KNOW how old THAT is.
Except USB C while maintaining its shape and size has made advancements nearly every year with download speed and bandwidth.
Which PCI 4.0 is exactly as it was when it was introduced.

So yea, PCI 4.0 on a $7000 BASE PRICE machine is LAUGHABLY NEGLIGENT in 2023.

Hate to break it to you but Sun and DEC are long dead. Even workstations now typically use commodity hardware.

So, yeah, if you buy a branded "workstation grade" SSD expansion from - say - HP - you will be royally gouged - but in most cases you could just buy a M.2. stick and plug it in. I have an old HP "micro server" which were being off cheap years back & the "official" plug-in hard drive modules were $youmustbekidding - but not only could you fit a regular hard drive in the existing sled. you could get cheap no-name empty sleds on Amazon.

Problem with the Apple SSD situation is that the modules are (a) proprietary and (b) probably can't be cloned by third parties "because security" (AFAIK the Apple Configurator won't accept unofficial parts and without that they won't work) - although with the MP you'll probably be able to use M.2 to PCIe adapter cards as long as the MP has official SSD modules installed in the main slot.

The other question is how much these things actually cost if you have a business contract with the supplier. As you say, they're not consumer products, so retail isn't the main sales channel - you have your people talk to their people and haggle.

Apple used to have expandable tower Macs that were accessible to "prosumers" and you can certainly get affordable PC PCIe towers retail. I think the need for massive upgradeability is receding - even RAM and storage requirements aren't doubling every year the way they did in the "good old days".
When I was in school I was coding on an SGI that retailed for $90,000. Having your workstation storage upgrade cost 1-2k IS cheap. This is the storage that goes with a system that starts at $7k, has 800gb/s memory bandwidth and 8k/240 output and can process 22 8k video streams simultaneously. You don’t do that with a commodity m.2 drive.

If you don’t want to spend that, I’m sure OWC will come out with an alternative. Or you could just buy the consumer product line instead. Or pay less to get the better drive at the time you buy the computer. Or use a USBC drive. Or offload your archive projects to a NAS or external raid. If you’re not able to budget this stuff, you’re not in the market segment that it’s for. You’re in the market segment that thinks it’s ridiculous that the Pro Display costs more than a gaming display and don’t even have freesync.

Good point. Still, though, I’d recommend not looking into the outlet it has to plug into.
 
Nonsensical pricing for the storage, as everyone else has commented. Also a ridiculous jump in price between the Studio and the Pro, just to get hold of some PCI slots...

I suspect Apple intended to create a superior Ultra chip for the Pro, or bolt multiple ones together, but failed... and were just like "screw it, just stick the chip we already have in it, and keep charging a damn fortune"
 
For me that I have original Mac Pro 2019, hearing that these ssd substituted ssds of the previous model makes me go crazy. What if I want to upgrade them? Cannot.

And one more thing: Mac Pro pre 2013 could change logic board With an expanded kit.
it‘s ugly that a power workstation from 2019 with Intel processor cannot be upgraded to M1 With a special kit To do it.
 
Those prices are high, but when you look at the price of the Mac Pro to beging with it’s targeting a select group of people/creators. I think most people complaining about the price have no need for a Mac Pro and would never buy one. Me included.

To those complaining about pricing, this is not consumer hardware. This is workstation hardware. Workstations have always been priced like this. You just never paid attention because Sun and DEC didn’t have the same exposure to the consumer market that Apple does.

For the consumers, you can have a Mac Mini or Studio and add a USBC drive.
What makes it different? Are they SLC?
 
No upgradable RAM and no 3rd party GPU's. Major fail.

Not everyone is going to rewrite apps for apple GPU.

That is probably due to the way the CPU (die / soc) is made, it comes with ram and gpu in one block. So no way to provide user upgradable memory expansion.
 
A lot of people in here annoyed about the cost of the proprietary SSD as if they were going to buy the $7,000 computer in the first place! I agree it’s outrageous *but* this Mac is not made for us. It’s the same reason the stand on the Pro XDR is so expensive. It’s the same reason the wheels are so expensive. It’s because big businesses will hand that money over to Apple without care. Apple isn’t trying to fork you this time, they’re forking other businesses.
 
Lol, insane pricing. What’s the point of modularity when you’re still paying Apple tax on components? Wonder if there will be third party solutions at some point.
there are third party solutions to install nvme drives to PCIE slots.
 
How is this pro-friendly?
I honestly believe the mac studio was a much better thought product.
It is perfect for what it is, at the right price (given the apple tax of course).
I like my M1 Ultra studio and, although I'd love a little more GPU power, it has served me well.
 
I wonder how different these are than the modules in the Mac Studio? If this means the Studio can also be unofficially upgraded then we'll see 3rd party options very soon. The Pro is just too niche.

Some music & video rigs require(d) PCI expansion cards (although many have moved to thunderbolt). Some heavy computing or server tasks require masses of high-bandwidth storage so either PCI-NVMe cards or fibre/SAN connections. Those are the two tasks I am familiar with. Thunderbolt 3/4 maxes out at 40Gb/s. PCIe 4.0 starts at that speed.

But yes, this machine is very, very niche—even more so that it only has one processor option that is shared with the cheaper Studio.

...and which, today, would be given a run for its money by a $40 Raspberry Pi, let alone a MacBook Air. I don't know what possible relevance you'd think that would have beyond showing how dramatically technology and prices have changed since then. Or, to put it another way, if you had the thick end of a quarter million ($90,000 in 1990 plus inflation) to spend on a specialised system in 2023 there are options that make the $7000 Mac Pro look like an abacus.

"Workstations" - insofar that the term has any meaning beyond marketing - back in the day were a half-way-house between an 8/16-bit PC and a minicomputer using radically different technology. Workstations in 2023 are high-end PCs (or, in this case, Macs) using mostly the same technology as high-end consumer PCs.


This is the storage that goes with a system that starts at $7k, has 800gb/s memory bandwidth and 8k/240 output and can process 22 8k video streams simultaneously. You don’t do that with a commodity m.2 drive.
It's also exactly the same storage that goes into a $2000 Mac Studio Max with the same bandwidth or a $4000 Mac Studio Max with same processor (unless Apple have gratuitously made the modules a different shape) and - as far as we know - the same flash chips that are soldered into a MacBook Pro and the same chips you'll get on the better class of 'commodity' M.2 card. The difference with a M.2. card is that it is more complex and includes a controller chip, whereas Apple builds that into the CPU. Yes, Apple's method wrings a bit more performance out of the chips but there's nothing magic about the flash chips they use & which account for the bulk of the materials cost.

...with PC workstations you can argue the toss about ECC memory or Xeon processors having extra features, but with the Mac Pro there's no ECC (whether that's important with Apple's LPPDR RAM arrangement is debatable) and the processor is just a scaled-up version of the M2 Pro chip in a $1300 Mac Mini. The only distinction between the Studio Ultra and the Mac Pro is now an over-engineered case and 6 PCIe slots (usable bandwidth c.f. external TB4 enclosures to be announced).
 
If M.2 adapter could work it would be stupid for Apple not to have M.2 slots on the motherboard. Also, if the adapters worked who would buy Apple's own overpriced SSDs?
As far as MacOS is concerned, an M.2 card in a PCIe adapter is no different (maybe a tad less latency) to a M.2 card in an external Thunderbolt adapter or the better class of Thunderbolt external SSD. Apple would have to quite gratuitously block it to stop it.

An M.2. slot on the motherboard would have to share (or subtract from) the limited PCIe bandwidth with the other PCIe slots so it's arguably more flexible to let people plug in M.2 adapters (at one point there were also non-M2 full-sized PCIe SSD cards but I don't know if they're still a thing).

Also, I don't want to go to far on a limb here, but I think x86 processors allow some PCIe lanes to be optimised for NVMe use, which would be used to drive the primary M.2 slot. Apple offers their proprietary on-chip SSD controller for that. Apple $$Ds are a tad faster and arguably more secure than regular M.2 - although not necessarily the sort of night-and-day difference that would justify the prices.

Anyway, you can't boot an Apple Silicon Mac without a working Apple SSD and anything 512GB or bigger should be enough for your system and apps - so it pretty much makes sense to use that as your system drive.

I wonder how different these are than the modules in the Mac Studio? If this means the Studio can also be unofficially upgraded then we'll see 3rd party options very soon. The Pro is just too niche.
It doesn't really matter if the Apple parts are all serialised and the configurator you need to run to get the Mac to boot again after changing the SSD talks to Apple and decides whether you're allowed to use that part. Apple already sell replacement SSD modules for the Studio but you need the serial number of a compatible machine to order them and you're only 'allowed' to use them as like-for-like replacements. It is also true that - because these are raw flash cards with no on-board controller and firmware - there are multiple types of module and the right type has to go in the right slot on the right machine... so it is a bit unclear from what you see on YouTube how much is people doing it wrong and how much is arbitrarily enforced by the configurator (its a rather expensive experiment)... That said, this all stems from Apple's design decision to control upgrading and replacement ("because security") - as anybody who remembers configuring hard drive parameters in a PC BIOS will know.

So unless Apple gets rid of Apple Tax on their higher-specced computers, I currently see four niches where Mac could excel:
[snip]
  • Workflows that require huge amounts of GPU memory
Relatively speaking. 192 GB of memory is “huge” by prosumer and video professional standards, but it's tiny when compared with the old Mac Pro's 1.5 TB limit. There were certain use cases, such as scientific applications where huge datasets might have to be stored in memory, for which these Apple Silicon Mac Pros are not longer suitable.

I'd love to see Apple offering memory expansion again for those use cases, perhaps in a future iteration of the Mac Pro, but I'm obviously not holding my breath (also, that would discourage users and developers alike to make use of the ultra-fast unified memory architecture; on the other hand, maybe it becoming ubiquitous, and the Mac Studio remaining the obviously more popular machine, will ensure that, so not offering memory expansion on the AS Mac Pro may be overzealous – or even lazy – on Apple's part).
