Going to Apple silicon & Apple GPUs; the only real need for full-size PCIe slots would be the audio guys...

But I would think TB4 could handle a LOT of that need by then, either from faster "breakout boxes" or straight-up PCIe expansion chassis; Apple could do an "Applified" PCIe expansion chassis that bridged several TB4 ports together for increased bandwidth...?

So yeah, back to the "expansion by cable" method, tied & true in the finest of Trashcan ways...! But hey, is that not also the same model as the entire laptop & iMac line-ups have; expansion by cable...?!?

Actually, my idea of a new Mac Cube (see below) DOES have expansion...

It's just, well, proprietary expansion...! Yay...! Daughtercards...!

So the MPX-C (Compact) is not really like the "additional slot dealio" of the current Mac Pro, it is an Apple proprietary super duper high speed interconnect, because you can only get daughtercards from Apple (for now)...! ;^p

Enjoy...!

Mac Pro Cube

48 P cores / 6 E cores / 96 GPU cores - CPU & GPU Chiplets on interposer / System in Package (SiP) design
HBMnext Unified Memory Architecture - 64GB / 128GB / 256GB / 512GB
NVMe SSDs (dual NAND blades) 2TB / 4TB / 8TB / 16TB
Eight USB4 / TB4 ports (plenty of expansion ports for external drives, displays, a/v interfaces, control surfaces, etc.)
Two 10Gb Ethernet ports
One HDMI 2.1 port
Four MPX-C slots (for use with asst. MPX-C expansion modules)


Apple MPX-C Expansion Modules

NVMe RAID Storage Module (Quad NAND blades) 4TB / 8TB / 16TB / 32TB
GPU / GPGPU Module (96 cores)
FPGA Module (audio/video)
Neural Engine Module (AI/ML)

The perfect personal workstation for a wide variety of tasks...!

Imagine the below, big flow thru heat sinks on all the needed bits, massive 200x30mm Noctua fan on the front, chugging air thru the system; just like the three fans on the current Mac Pro do...

people may want sdd's / hdd's in case or at the very least M.2 (not the apple one)
 
Without the bays to hold additional drives, people might as well buy a mini and an eGPU.

I would go for a Mac Mini but the GPU is not good enough and I hate clutter so the idea of an eGPU and another cable to hide is offputting.
 
Apologies if this has already been brought up, but this could see the return of a multi-processor Mac Pro: the 'A' chips cost Apple next to nothing compared to the several hundred to a few thousand dollars that each Xeon costs. Sticking four twelve-core chips in there might cost Apple a hundred dollars, based on estimates of 'A'-series chips to Apple. Add to that the vast engineering simplification brought about by the reduced thermal load, and we might see the return of a £2500 Mac Pro... we can hope.
 
I have to wonder what they'll sacrifice to make it half the size? Probably ditch the AMD GPUs. Maybe even several PCIe slots, as well. I fear we'll see another trash can Mac Pro, and then Apple will have to relearn that some people want modular computers.
I think you are right in that it will sacrifice some expandability. BUT ... It will probably be announced after a revamped Apple silicon version of the current Mac Pro at the same event. Followed by the Mac Pro Mini announcement. Still be expandable and upgradeable, but aimed at less computational heavy professionals like designers and still photographers as opposed to simulation, 3D rendering, video post production etc. For a more affordable price.
 
Of course, it is smaller. It's basically just an iPad in a metal box. Some more RAM and some more ports but in the end. it is an iPad.
... Pro, and with more cores, at a higher clock speed thanks to more liberal heat dissipation, and with one or more third party dedicated GPUs, and quite a few more I/Os actually, in fact enough to run dual 27” 5K monitors. Still an iPad? Really? ;)
 
Maybe the Mac Pro Mini will Look like the current one but smaller with, say, 4 slots; then offer a separate chassis for more slots, a bit like how they did with the XServe and XServe RAID. Presumably Apple are hedging their bets on their own GPUs being better than the full sized cards it currently uses. Will it still support 1.5TB?
 
This might be a dumb question.. Are there any systems with dual socket ARM processors? Also.. When these processors access ram is it the same process like a CPU x86? Dual socket systems for example need 128gb of ram on each CPU for a total of 128GB for the system. Am I way off?
There are dual socket Intel processors, but Apple isn't selling any dual socket Macs. You'd need a _huge_ number of cores to have an ARM processor where making it multi-socket and putting two into two sockets is easier or cheaper or faster than making a single ARM processor with twice the number of cores.

As far as the RAM is concerned: No, you don't need twice the RAM for a dual socket system. You may have tasks that need say five GB of RAM per thread, so with twice the cores you'd like twice the RAM, but that's based on the total number of cores, not the sockets.
 
I think we need to wait for next weeks event to understand what AS is capable of and if they really can reduce the size in half ... I mean this in the context of upgradeability, slots etc and thermals ... AS should not need as much cooling as Intel, but, why through this design out when you could use it to further kick performance ...
Why does everybody think it will replace the full size Mac Pro? Did the Home Pod Mini replace the Home Pod? Did the iPad Mini replace the iPad?

No, they are using the M suffix parts, that’s how they can support 1.5TB in the 24/28-core machines.
Ah my mistake; thought they maxed out at 1TB

But yeah (as a side-note, not in reply to the above), as always my beef with the Mac Pro is not the price of what you get, but that unless you want an all-in-one, they simply don't offer anything in between a Mini and a Pro. I.e., I don't have a problem with the Mac Pro per-se, my issue is the lack of something less high spec but not an AIO.

I mean what if I want to use a 55" display (for example)? I'm stuck with a Mac mini, a MacBook or some awkward iMac in the corner... and no, airplay to an AppleTV isn't really a great solution.

I get why, but as I'm sure everybody has heard many times before - I believe there's a definite market for something that can do some basic expansion with consumer parts.

e.g., something like an i7/Ryzen with at least

  • 1x PCIe x16 (for GPUs)
  • 1-2 PCIe x4 (for add-in card(s) of your choice)
  • removable/replaceable RAM
  • on board M.2 slots
  • at least a couple of SATA ports and bays to put drives in.

Pretty sure apple will never build it (especially now that consumer machines will no doubt be built-in Apple GPUs only) but we can dream - there's a massive gap between "I'm happy with an AIO iMac with zero internal expansion" and "I want workstation components and 1.5TB of RAM capability".

The iMac Pro kinda misses this point, its just a higher spec iMac with many of the same restrictions. Which is fine if you want a fixed configuration box you buy for your business and then bin after 3-5 years, but if you're a hobbyist any of Apple's Pro desktops are big money for limited spec.

You might have missed the point of my post.

We already know the ArMacs will be targeting laptops. That where their performance will be optimal and most improved, no doubt, over the Intel counterparts (where performance per watt is concerned). What we don't know is how this strategy will scale up to compete with a full workstation (what this post is actually about). That is, what will an unconstrained ArMac look like? That's an unanswered question which is why it's more interesting to me. For instance, if the performance ceiling is around where the MacBook Pro equivalent will be, then certain professional creative applications won't be able to be performative enough to remain on the platform.
We may have an idea on how well ARM itself can scale via Amazon's Graviton2.
Also, while Intel deserves the flak for their lack of innovation in the cpu side, Nvidia in particular is very aggressive with their gpu improvements. I would be very surprised to see Apple not offer full discrete GPUs in this enclosure, as they would be competing with a very large amount of configurations, price points, and TDP if they went just their own silicon for both CPU and GPU for everything from a MacBook Air all the way up to a MacBook Pro.
If that was the case Nvidia wouldn't have put up $40 billion to try to buy ARM...though that has turned into a three ring circus of confusion.

One of the problems with having a large hardware variance (ie like a wide selection of discrete GPUs) is driver support and given how much a disaster of having a wide varience Apple had with the clone program in the 1990s they do not want to repeat that mess. Also ask yourself who wants a discrete GPU outside of high end professionals who will either have a GPU case via the USB-C or a card in a Mac Pro. Gamers? As has been pointed out the mac gamer market is so small fry that the number of games is way smaller then in the PC (which intern is even smaller then the console space)

Though I must admit that there are a number of game what run on linux and windows even through linux has even less of a marketshare than the MacOS does (and the excuses for this are such BS that I can't believe they are made)

Well there is the eGPU option though I have to ask just how many people outside the low end Mac Pro crowd will use 1-2 PCIe x4 and given USB 3.1 Type-C is faster then SATA III why in the name of sanity would you want something with slower through put?! Never miming that if you ling out an iMac Pro you are going to go past the ~$7000 for the lowest end Mac Pro you can expand. iMHO you are suggesting a product that given its nitche audience is effectively the solution to a non-existent problem.

Could an Arm derived CPU power a beast of a computer? Xeons are no pushover. Will they throw in like 4 CPUs each CPU with 12 cores?

But given their design the Xeon's power comes with a cost in terms of price, power needed, and heat produced. Amazon wouldn't have gone ARM (Graviton2) if it thought the Xeon was "worth" it. In terms of processing power per Watt ARM cleans the Xeon's clock, cleans it again in terms of power per $ spent, and yet again in terms of processing power vs heat ratio.

The only thing Xeon really has going for it is the ability to run x86 natively.
 
The new lineup:

Mac Pro max
(The current pro, gets renamed)

Mac Pro
(New half-size model, Apple Silicon)

Mac Pro mini
(New Mac mini, Apple Silicon)
this lineup is purely your imagination. it won't happen cause it will complete dispute the current Mac desktop lineup, including Mac mini and iMac or iMac Pro. your imagination pretty much wipe out all Mac desktops. like I said, why so serious on the rumours. apple lab can create different prototypes for R&D. for professional (not YouTuber) real professional they want expanailbilty and configurability so the size of the new Mac Pro won't be small; apple won't put themselves into the situation of Mac Pro 2013.

think of the whole apple lineup instead of your imagination.
 
With 3.5inch drive bays now antiquated and 2.5 inch drive bays antiquated and SATA antiquated ... and blown to bits by tiny NMVE M2 drives .. the need for large enclosures has been significantly removed for most users. I am quite excited to see this, and can see it as the replacement for my beloved R2D2 trashcan Mac Pro.

hopefully back to a trashcan design for that step between a consumer iMac and all powerful Mac Pro.

most systems don't have the lanes to drive more then 1-2 m.2 drives. And you want raid 1 min 2 disks Raid 5 3 Raid 10 4
