Nobody should really need this unless they are billing their time. Mac Pros (all workstations basically) are bad investments unless you are billing out your time to do something only they can do or at least do faster. Those that claim that buying a tower helps them future-proof their investment because they can always upgrade it have really not understood the last 2-3 decades of computing advancements.
Yeah… that’s me. I needed a Q840v to record video in the 90s… I don’t now… still absurdly priced but… I’ll go find a new work flow and ideology.
 
I literally have no idea who is this machine for apart from some super-duper niche music makers who need an edge in power and PCI slots. This is like 0.00007% market share. W T F
It sounds to me like you have a VERY good idea who this machine is for, to me! Good Job!
 
The Mac Pro top configuration could certainly have 128 GB of high bandwidth VRAM (with 50 gigs for system RAM). Are there any non-Apple systems that can be configured with a 128 GB of graphics RAM?
The bandwidth of M2 Ultra is WAY slower than workstation GPU which is totally meaningless. Having more VRAM doesn't really mean it's faster and there are so many factors to consider. Beside, Apple GPU itself is way slower than RTX 30 series so VRAM doesn't mean better or faster.
 
BUT... if Apple allowed NVidia RTX or Quadro cards to work in the new Mac Pro... they would sell a ton of them to the kinds of people who need CUDA and other things. Right now those customers are forced into Windows machines.

The Mac Pro only appeals to a small niche market... so why are they making it even smaller?

🤔

It doesn't make sense to me either. It wouldn't be cannibalizing their existing hardware sales, so what's the downside?
 
And you obviously haven't spend a single minute in the Mac Pro forums, apparently. As a reminder, we went over 2,000 DAYS between the 6,1 & the 7,1.

We still have people upgrading Mac Pros that are almost old enough to vote.

All of the original cheesegraters were very easy to upgrade and future proof.

Look at my sig - that was the configuration of my last Mac Pro when I decommissioned it. And I moved 2 of those cards over to my current Ryzen box.

I ran that cheesegrater for 9 years; I replaced the CPUs, the GPUs (three times), upgraded the optical drive, replaced all of the hard drives (twice), and filled all of the PCIe slots. Two of those PCIe cards have since transitioned to my current computer.

Forums full of people whining becuse they are trying to squeeze the last two cents out of a machine by throwing a 100 more dollars at it. Sure, you can fiddle around and add some cards, slip in a faster CPU from the same vintage as the machine, maybe add a little more ram, heck maybe even max it out beyond what Apple said it would support new, but in the end you aren't really taking it any further than what you could have just speced it out when it was new and certainly not anywhere near what a modern machine supports. Really a bad investment as a personal machine and a lagging relic if you are doing paid work on it.

I have 4 cheese-graters in my garage, a 2006, 2008, 2010 and a 2012. (that's not even counting the 2 G5s that have long since been recycled) I moved to a 2013 trashcan and then opted for the iMac Pro which I replaced with an M1 MacBook Pro and then eventually with a Mac Studio Ultra. Each upgrade was justified by revenue and workload. The old hardware was depreciated and written off. I didn't have to crack open cases and fiddle with upgrades and scour forums looking for driver hacks or patch the OS. I kept my hardware current and supported and I didn't miss a beat.
 
I was really hoping Apple would stick with ECC RAM in at least the Mac Pro, and in my wildest dreams, add it to the updated Studio as well. In reality what Apple dis is save me a **** ton of time and effort that I was going to expend developing ZFS to work flawlessly with Apple Silicon Macs. Without ECC RAM, there really is no point.
 
I get it. However, one of today's great mysteries is where the new Mac Pro gets its PCIe lanes from and what the actual bandwidth and number of available lanes is for those slots - so far all we know is that the physical size of those slots. The Sonnet adapters offer 16x and 8x slots but (as you pointed out) that doesn't mean they get 16x or 8x bandwidth.

As far as we knew, the Mx Ultra's i/o consists of enough PCIe to run the ethernet, SD slot and USB-A ports plus 8 TB4 ports. Either the M2 series has been keeping a shedload of unused PCIe lanes under a bushel or those PCIe slots are somehow sharing bandwidth with the TB4 ports. The "worst case" solution would be that Apple have just built a TB4 to PCIe bridge into the MP...

I recall one of the first Mac Pro rumors was a double rumor, that 2 were in development. One would be a similar form factor, and the second would be a much more compact design. The second turned out to be the Studio, of course. Do you guys recall that early rumor, and who made it? I think it was in 2021.
 
The Mac Studio is not exactly what I would call expandable

I was referring to external expandability via the 4/6 Thunderbolt ports (and have edited my original post to make that clearer).

But as I noted, the 2013 Mac Pro also had 6 Thunderbolt ports, but for people whose work flows were designed around components that connected via PCIe expansion cards, that meant either having to move to an external solution or purchasing external Thunderbolt enclosures to place those PCIe cards into which meant that "elegant small PC" was surrounded by boxes/enclosures.

That was Mark Gurman at Bloomberg:
 
If not, I really don't see what's so special about this MP model that could make Mac Studio users switch up, or even pull in more potential customers.
There’s nothing special about it. It’s just another computer doing computery type things that a small (compared to all the non-Mac platforms) number of folks will choose to work and make money on or just use. And, Apple stands to profit in some way from a percentage of those users/developers efforts.

I think they said the new Studio is six times faster than the fastest Intel iMac...
That’s what I thought I heard, too. Just finished the Platforms State of the Union (will likely fire up the ‘mac for gaming’ threads with the stuff starting at 27:30 ;)) Haven’t watched the Keynote again yet.
 
The MBP is a nice computer but not a halo product. You are likely correct, they no longer have a halo product.

Welcome to a repeat of the waxing days of John Sculley.
Agree, or disagree, Vision Pro is now Apple's halo product. That's their vision of the future.
 
I understand this "niche" customer for these systems. But it still seems like a ridiculously overpriced solution for a problem that could be solved other ways.
Absolutely right. This Mac Pro is made ONLY for those cases where it’s a ridiculously overpriced solution that CAN’T be solved other ways.
 
Are their any comparisons showing how much faster discrete GPUs are over the M2 Ultra?
The comparisons I’ve seen are using code that’s been highly optimized for Intel/Nvidia systems for years. So, while comparisons are out there, they’re likely using code that’s not tuned for a TBDR display path. It’s a useful comparison, but not for raw performance, more for answering “which one does best running the code that’s been tuned for Intel and Nvidia solutions?” The answer is never surprising!

Could have told you that yesterday.
You could have told them back with the FIRST Apple Silicon was released. :) Apple made SUCH a big deal about it during their initial developer videos about how Apple Silicon systems are different from Intel Macs, it was clear that there were going to be the same number of third party GPU’s for Apple Silicon as there were third party GPU’s for the SoC’s they created for the iPhone. :)

I honestly thought they'd do a fast unified RAM / slow expandable RAM split. Where you basically fill the unified RAM first, and then you hit the slow RAM (and maybe limit what goes there with flags/rules). But apparently, no.

For the M3 version, perhaps?
No? Because the reasons for why they didn’t, haven’t changed, really.
