A question though on the highlighted sentence below — am I reading it right that Windows would require a stronger machine to run well? It may be an aspect for me to consider since I plan on running my Hasselblad film scanner via Windows.

Windows being supported over a longer time opens the door to a wider set of GPUs. Pairing a 2019 era CPU with a 2025 mid-upper range GPU may end up in a situation where the GPU is hampered because the CPU just can't keep up (e.g., feed data quickly). 2026 , 2028 GPU and 2019 CPU the gap will just get wider.

For better or worse, the MP 2019 is capped on possible GPUs which also stopped in the 2022-ish timeframe. So no chance to have a gap form there between CPUs and GPUS.

It is the difference between wanting to use the device as a system (holistically as a Mac ) or as a 'box with slots' to fill ( to do whatever OS want to throw at it). The latter has a wider range of permutations that bring their own issues.

Just renewed AppleCare+ on mine. Good to have that.

If I need to use it, I don’t know what they will do, give me an M2 Mac Pro?

Well that would be an interesting case, Australian law is pretty aggressive for this sort of thing. I think Appe is already on very thin ice with regards to not stocking MPX modules, SSDs etc, because provision of spare parts for a minimum of 3 years after a product goes off sale is a legal requirement.

It would be a very easy case to make that you purchased insurance for an Intel machine with upgradable GPUs and the ability to boot Windows, and they need to provide you with that for any warranty fulfilment.

It's something I plan to follow up myself when I get a few spare moments.
 
This was probably Apple just not wanting to have their M2 machine being out performed by a previous machine, and to try and ensure that people will throw away more big $$$, which I refused to do.

Probably not. It is likely driven by the fact that the rest of the Mac line up dropped AMD GPUs. There is no unit volume to support the driver development for a new GPU implementation.

The 580 in the initial MP 2019 was a 'Polaris' class GPU that was used in other Macs ( ).
580X in 2017




The 5000 series was used in the iMac 2020 and MBP 16" 2019




Vega II is a follow on to Vega used in Mac Pro ( there is some unique work there).



The Mac Pro got 6000 series probably Apple knew they were going to try to do the Mac Pro at the end of the two year transition and just needed some 'fill' to kick the can down the road. Also partially driven by problems that Vega II presented ( AMD skipped a 'large GPU' solution for the 5000 series because of birthing hiccups in their GJP family development). The 580 was also 'old' on day one also. Essentially, got a bump there because AMD didn't deliver on time. ( AMD probably soaked up a sizable chuck of costs for that just to hold onto the declining contract just to keep a steady customer with deep pockets. )

Apple likely told AMD way in advance that Mac Pro 2019 would drop from market in late 2022. That probably changed to 2023 later, but the Mac Studio would have been out by then it the writing on the wall in bright neon lights for AMD. At that point, if no new systems being sold what is the market 7000's? Relatively not much ( in context of crypto and then AI mania crazes ).

It isn't tech benchmarks porn numbers that stop new dGPUs. It is just plain economics. If Apple isn't spending any money on it then AMD isn't going to either. AMD subsidizing Apple is nuts. [ If AMD unilaterally did the drivers then most MP users would buy the Windows PC market version of the cards and AMD would recoup little to none of the money spent. So yes, that would be an Apple subsidy. ]

It is the same detachment with the notion that Apple could just keep macOS on Intel going forever with zero new product being sold on that platform. When the rest of the mac line up dumps dGPUs... the Mac Pro pushing that up the hill all by itself doesn't work.

Has anyone managed to rig the 7.1 with an NVIDIA RTX 5090/ Pro 6000 Blackwell? And if so, what worked and what didn’t?

If trying to run 5090/Pro 6000 inside the Mac Pro then one issue is that pragmatically it takes both MPX bays worth of power. (going to need all four 8-pin power delivery. And won't be uniform cable length for all four.). You won't have much room or power to run a smaller GPU in the non MPX bays for macOS. If skewed that much toward Windows to loose substantive GPU 'horsepower' to macOS, why bother?

If put in an external enclosure with a modern 16 pin power supply then wouldn't matter as much.

I’m running an RTX A6000 along the Vega II Duo for years with no problems and was wondering if swapping that for the RTX 5090 would help out. When you suggest external, what enclosure do you have in mind?

CUBIX / Cyclone / Max Expansion / One Stop Systems PCIE expansion chassis pop up on ebay a few times per year.

I'm a satisfied user of One Stop Systems (formerly maxexpansion) CUBE3. It has been attached to:

- Proxmoxed Z820 with variety of GTX 1070s and Vega 64s
- Hackintoshed & proxmoxed HP Z840s with 4x Vega Frontier Editions and / or Vega 64
- MP 2019 Big Sur dual W6800X duo + 4x Radeon Pro VII in the same CUBE3. These PCIE expansion chassis are worth their weight in gold, and allow your box to take on some massive tasks, effortlessly.

Absolutely loved my system, but ended up selling it. I found I was using Windows on bootcamp more and more often and there was some games & software released or soon to be released that require secureboot to be enabled. Unfortunately you can't do that on bootcamp.

Ended up moving the system onto someone for a great price for them, and more than enough for me to build a beast of a PC.

It was fun my guys.

Theres a video of someone doing it without an issue on the RTX5090 Founders Edition, it even fits in the case perfectly. They just had to get an additional AUX power cable and a splitter.
 
The ridiculous thing is the RXT5090 FE isn't even in Australia (officially) and the 32GB cards from the third party brands are at $5000+, even AUD$5799! No way spending that.


No problems with it being "in stock", because very few are going to be interested in spending that amount of money.

Recommends ROG Thor III PSU 1600w/1200w. 😳

Any link to such video? Have not seen any.

There's a segment in this video at around 2:15 min where he shows a schematic from someone who set one up, but I can't find that link. He mentioned who it's from but I didn't google around much to find it. Here's a screenshot.

By the way, just being cheeky. I have a bunch of the Belkin PCIe power cables I never used, currently on eBay for considerably cheaper than what Apple charge.
 
Max tech is reporting m5 ultra is coming this summer and will be fastest cpu and gpu on planet.

It’s been an amazing 2 decades, Mac Pro bros, but I think it’s finally over.

The chincey number of ports on the back and the idea of a half dozen cables connected to exterior devices to produce an ugly and cluttered workspace makes me want to vomit, but I think I can get over it for the fastest computer ever.

I am thinking if it’s possible with a W6800X MPX and the 5090FE. I suppose size constraints will mess things up because the MPX modules are quite bulky.

The M series is pretty amazing especially Max and Ultras, but i highly doubt the Ultra reaches 5090 levels for raw power. Perhaps compute. Also gaming even with CrossOver is pretty bad on a Mac still, Apple needs to spend some billions in this department. The Ultra will cost $10k (at least the amount of RAM I personally want.

Also you can hide the Mac Studio under the table by flipping it upside down and mounting it in the back of your table and running the cables that way.

I don't see why not. The MP Power Supply is 1400 Watts, the MPX module eats the power from the second proprietary slot next to the PCI lane, then you can feed the 5090FE with regular AUX cables from Belkin like others are. There's 64 PCIe lanes on the MP, which is more than enough to run 3x full PCIe 16x cards, even though macOS won't use the 5090FE.
 
Personally, I will not buy a Mac Studio. I don't like the latest macOS Tahoe and Liquid Glass at all, and I don't want to spend €10,000 for a closed box, non-upgradeable machine. However, I will buy a ThinkStation P to replace my Mac Pro, with Linux, dual-boot Windows for a few apps.

What spec's are you thinking ? With ram prices it could get expensive.
EDIT : Not Studio expensive. lol
 
Perhaps this is good news for those of us who are happy amateurs and can accept the constraints of the 7,1?

I hesitate between three models: P5, P7, and P8. The processor isn't the most important part for me, but at least 12 cores, and then the ability to add two GPUs, RAM that I can upgrade later when prices will be better, and NVMe and NIC cards. I'm considering something as expensive as the Mac Pro 7.1 was, but more upgradeable, without the constraints of proprietary formats, and with the operating systems of my choice.
To be honest, I wish Apple had kept the Xeons (or Threadrippers) for the Mac Pro, the large number of PCIe lanes, and I wish Nvidia cards were compatible with macOS. I don't understand the point of hindering users by not updating compatibility for AMD 7000 and 9000 series cards... I don't understand this approach at all.
So, as I've already said, for me, Apple is still great for laptops, Mac mini, iPad Pro, and iPhone, but not for workstations. I should be able to decide what I do with it. The user should be in control of the machine, and the system shouldn't restrict the use; otherwise, I'll switch to another system. I believe it should be at my service. I don't want subscriptions, or as few as possible; I want maximum upgradability.
Why did users love the Mac Pro 5.1, and even the 7.1, so much? For these reasons. Honestly, the Mac Studio is very good in the lower-priced configurations. But above a certain price point, I want at least the ability to upgrade the SSD, keep my data if I resell the machine, or replace it if it's worn out or too small. Basically, simple freedom. I don't see what's so extraordinary about just being able to install a basic NVMe drive. I want it to be my machine.
