I described the foot print in an earlier reply. Imagine something the size of 4 Mac Mini’s stacked to the height of the 2013 Mac Pro. That is four separate squares stacked to the height of the Mac Pro. That’s why I keep using the NextCube design.
The NeXT Cube is more so a horizontal stack ( enclosed in a case) than a vertical one. It also wasn't all that popular or effective use of literal desktop space.
This whole "stacking" thing does really scale well in the 350-500W range. It is marginal for a relatively low power consuming mini but once have to cover a range with either a much larger diameter fan and/or multiple ones it gets awkward keeping multiple dimensions "squarish".
That’s a lot of space to accommodate powerful Xeon based processors and high end graphics. A single Mac Mini is not that small, imagine four of them in a square. That’s a lot of space for components to support an appropriate thermal environment with other components.
The Mini turns the airflow 90 degrees which isn't maximizing for efficiency. The power supply is gong to grow in volume. The fans will grow in volume. If looking to top out the video card around the 250-300W range it isn't really enough volume for relative low speed airflow but still high enough cubic feet per minute. ( If try to cover two , 500-600W it isn't even close. )
The Cheese Grater Mac Pro was necessary for its time because that was an era of mechanical disks and optical disc drives and extremely hot processors. None of those are gonna be in the new Mac Pro. That in itself would cut out 25% of the tower Mac Pro.
"extremely hot processors' didn't go away. The roles flipped a bit. Instead of CPU > GPU, it is now GPU > CPU.
Optical is extremely likely toast, but Apple has their head in the sand about cost effective $/GB SSDs. SSDs and faster is a trend, but SATA 2.5" SSD at
way lower $/GB than what Apple chargers is a trend they'll miss. Apple could go just M.2 for additional drives, but max optional capacity is an issue. ( iMac Pro has two daughter NAND cards.... that's isn't really enough for a broader range of workloads.).
With DDR4 RAM, you will likely be able to get 64 to 128 GBs sticks, so if you want to fill this up with 512 to 1 TB RAM,
Xeon W is likely to cap out at 512GB. Even the W-3175X part that Intel brought "down" from SP land caps out at 512GB. Apple doesn't need 128GB sticks as much as support for 8 DIMM slots ( which still gets to 512GB with 64's ). [ and again 4 more DIMM slots is more volume that Mini sized augments really isn't enabling all that well. ]
it won’t require two sets of RAM trays.
Depends. The user space that want to throw 128-256GB of RAM at a RAMdisk and use another 64-128GB at "memory" pretty much are going to want dual DIMMs per controller.
Once up in the 64-128GB range of DIMMs, you not really in the "unbuffered" range anymore. And 8 DIMMs would be something that the iMac Pro 'doesn't do' ; which increases their differentiation. [ The whole "choose Mini based constraints" thing is largely going to drag the new Mac Pro back into an overlapping space with the iMac Pro. It doesn't make much sense. ]
The same goes for storage, in a profile like what I’m suggesting, I wouldn’t be surprised if Apple announces you could configure this with anywhere between 16 to 24 TBs of internal SSD storage.
"bulk" SSD via 2.5" SSDs is probably going to be more effective than through 3-4 M.2 . Cost wise. Also
Our concern has been what it will look like, it’s just a logical common sense design. I sense because we assume Pro with being a big honking tower, the failure of the 2013 MP and the idea of something looking like the mini would be another disaster.
"Too much Mini" has a high likelihood of constraining it to be too much like the iMac Pro. ( or worse).
One of the failures ( "thermal corner") of the MP 2013 was too tightly coupling the thermal solutions. The solution to that is more "space' between the two (or three) primary heat sources so they are decoupled. They may end up not being "off the shelf" thermal systems, but they will probably not to be decoupled in other not to get back into the same situation that proved problematical before.
Don’t get me wrong, it’s gonna be a bigger computer, it just not need to be enormously huge to deliver yearly upgrades without going back to the drawing board.
1. Is Apple really going to commit to yearly upgrades? ( That would be a good way of showing sustained, continued commitment, but is Apple really going to do that relatively high (for them) frequency ? ). Smaller doesn't necessary mean "faster updates". (e.g., the Mini over last 9 years. )
2. "High throughput" is more than just about GPUs. There are high end SAN/NAS cards ( even more so if Apple sticks with a small number of internal storage devices. ). 8K capture. "Princess and the pea" low latency capture/processing. etc. There is substantive utlity that comes from having even just one empty highly diverse slot. It would be kind of a unknown parameter which drives volume up to handle the possible alternatives. ( so bigger volume ) but Apple's long term tech crystal ball doesn't have to be 100% correct for the baseline design to survive over 10 years.

[doublepost=1557777284][/doublepost]Not the one pointed out by the "plausible" leaks I posted thus weekend
The real question mounting is way are any of the rumor sites taking this even seriously. At best this is a contrived Sock puppet of a "leak". It is off on 6-7 of the specs listed. Besides T2 and Bluetooth almost all of it looks off .
