Mark Gurman has a long history of making bad predictions, take what he says with a grain of salt.

Doesn't hit it all the time as Apple changes its plans but an 86.5% accuracy rate is amazingly good.

So with the latest from Gurman, and I do think he is correct, I can go do other things until some time in February when I can actually order my new Mac Pro.

ASi Mac Pro preview - Spring 2023

ASi Mac Pro full reveal - WWDC 2023

ASi Mac Pro shipping - early Fall 2023

But that ASi Mac Pro, with a 3nm M3 Extreme SoC (introducing hardware ray-tracing) and a brace of ASi MPX GPGPUs will be worth the wait...! ;^p
 
The Mac Pro will be a Studio Mac only twice as tall.
Actually it may be as big as the 2019 Mac Pro. Supposedly in the beginning of the planning stage for it Apple was going to produce a more simplified Mac Pro. By doing so they could have used the 2019 Mac Pro smaller version box but after abandoning the proposed simplified idea it could be the same size.

FWIW, rumour has it the dev box is housed in the current Intel Mac Pro housing.
 
I’ll believe PCIe slots when I see them. Apple did shock me by putting 8 on the 7,1 but I still bet there will be 0 on the 8,1. Rumors of 1 or 6 slots are quite recent and incompatible with previous rumors of a mini Mac Pro. If Apple is developing discrete MPX GPUs it would be the first time I’ve heard about it. Possible but unlikely.

To be clear, the rumours state PCIe slots AND no discrete GPUs. ie. The rumours are that the PCIe slots are not for GPUs.
 
Correct me if I'm wrong, but AFAIK, Gurman has not said if there are any PCIe slots.

“ While I don’t believe the first Apple Silicon Mac Pro will go on sale until 2023, I know that testing of such a machine has ramped up inside of Apple’s walls. ”


No mention of PCIe.

Right. The PCIe rumours don't come from Gurman.

No one ever said Gurman mentioned PCIe, the OP of this very thread (which you seem to be selectively reading) has stated that an earlier M1-based Mac Pro prototype had one PCIe slot, and a newer M2-based Mac Pro prototype has six PCIe slots...
 
While you are correct that Gurman hasn't stated anything around PCI-E slots, I DID resurrect this thread with THIS POST

Immediately following that resurrection, @Amethyst posted the following:


Furthermore, yesterday he added the following:



So to all the people that are still speculating, can we please stop?

@Amethyst has been spot-on with every single one of his leaks, so I believe his word over anyone else's at this point. All of the speculating (ESPECIALLY WITHOUT FIRST READING THRU THIS THREAD) is conjecture, and shouldn't even be posted IMO.
First of all, i've deeply thank about your believed in my post.

But, all of an information i've got is come from my friend who works on many of <<PROTOTYPE>> machine.
i really doesn't known about what final products look like, doesn't known it have PCI-E or not. as many of Mac Prototype that doesn't launch eg. MacBook Air with A12x + LTE in 3-4 year ago or last year 27" m1 max iMac.

Only things i can really confirm that is Mac Pro still in works now it contains monster of chip, has 6 PCI-E lanes and all packed in current 7,1 case.

BTW, there are some stage which my friends can confirm what final product will be (such as Mac Studio) and when that time comes, first place i will post my recieved information is here.

What everyone needs to bear in mind, is the original iMac, and at least one or two revisions afterwards, had a motherboard slot (Mezzanine slot), whose only purpose was board developmental debugging and factory testing. While the slot worked, and a couple of companies made cards to interface with it, Apple then removed the port through the case to deny any access, and then removed the slot entirely.

Just because a prototype has a slot, doesn't mean the product will have it, in any way or fashion.

Yeah but six slots?

A generic test-mule motherboard to develop drivers etc for components, before they're integrated into the motherboard itself?

If you want to go really wild with things, maybe the hardware being "seen" is just an overpowered rig to virtualise the next gen mac mini in a VM simulator that it launches transparently at boot.

We literally can't know what the upcoming machine is or will be from what we've heard so far.

Well, it started with 1 PCIe slot, and moved to 6 PCIe slots afterwards.

My expectation right from the start was that it would have PCIe slots, so if the final product does NOT have PCIe slots, I would be surprised.

Suppose for a moment... that there are actually two Mac Pro's being tested? An upgrade to the bigger 7,1 box with the "monster" chip that Amethyst mentions, and the smaller one for the rest of us? That could explain why everything Mac Pro is so delayed, in that Apple would want to bring them both to market at the same time. It seems to make sense to me.
 
This thread is gonna get verrrrrry long......:p
Could be another 6+ months yet.

My 'twisted' thoughts....
The ASmp in having an 'M' chip doesn't seem as 'beefy' as a Xeon to me.
In the old days, even when the Mini/iMac/laptops etc got new i3/i5/i7 cpu's, if your cMP was 5-6 years older, the fact it had a server grade Xeon seemed far superior, just in quality.

With every Mac having an M1/2/3 or whatever, it's a smaller step from one Mac to another, therefore 2-3 years after a soldered ASmp purchase, the new Studio will have a better processor, and your stuck with a £6k+ machine until you sell it.

Ok now try that again with 6 slots. I guess the prototype devs just tripped and fell and 6 testing slots landed in there. 🙄

Ackshualy...

It was six devs running to a meeting, each with a single slot prototype in their hands, and then a sudden collision caused the new six slot prototype...

Some peanut butter and chocolate may have also been involved...
