Who am I? I am an insider. I've been biding my time and have kept quiet (so as to not lose my job!), but I can't take this nonsense anymore. So here's my info, which is necessarily limited in detail (job to keep, remember):
  • Same form factor. No change in the color or anything else. The tube really was intended to last 10 years. Whether we'll see an update after this one is anyone's guess, though.
  • Slightly updated power supply (50 watts more). There is no way that the tube can fit much more than this (e.g., big enough to support arbitrary "2 full-length video cards") without becoming a mini Chernobyl and/or making an unacceptable amount of noise (for Apple, anyway).
  • Updated processors providing a minimum of 6 cores and a maximum that is not yet set in stone.
  • Updated graphics based on RX-480 variations. Top card is "RX-490" with DDR5X. This is where the extra power is going. Same graphics form-factor (no standard slots). People - especially anyone wanting to game on a 'pro - are likely to be grumpy about the graphics performance (worse than GTX-1080), but compute performance will be 20-50% better than the present variations.
  • A bone will be thrown and two flash drive slots will be available.
  • Merged TB-3 / USB-3 plus an HDMI port.
Announcement along with a new Macbook Pro in September. Immediate availability is planned.

This is definitely the type of disappointment I've come to expect.

Aw, it won't be that bad. Up-to-date and faster everything for the same basic price structure. Besides, what would be left to gripe about here if we got every (magical) thing we dreamed of?

By the way, the "no HBM-2" spec is due to delays in its availability. But the message from the masses has been received, and one could hope for a subsequent update with a more significant (and likely expensive) improvement in the top-end graphics cards in about a year's time.

Ahem. EVERYTHING will be faster than even fastest D700 offering :p.

I will not be satisfied with anything below Fiji chips in MP, or GP104-200.

And this is the biggest problem I have with upcoming update...

That's the spirit! We can start waiting for nnnMP now, even before the nnMP is announced!

But the alternatives are (a) old tech that is outside the power envelope, or (b) something that isn't ready and would be costly at least to start with, or (c) something that fits, is priced very well, is faster and can be delivered now (meaning September).

All in all, (c) is a good thing.

Nope, I will simply jump ship.

I'm half-way out the door too. My new Linux box at home is very fast and lots of fun. I haven't yet, but I could drop a GTX 1080 in it with ease. But then, the polish that Apple's Mac-OS provides does draw me back and, you know, I do have to use Apple products at work. ;-)
 
RX 480s? Why anyone beyond budget builders would be excited by those GPUS is beyond me. I guess they keep with apples traditional 'must utilize two-year-old GPUs' philosophy for Mac Pro, but honestly...

They will provide a distinct improvement that fits in the Pro's power envelope and will work very well with Apple's video software, etc. (ahem: VR!). But I put "490" in quotes, as these chips are likely being customized for Apple. Something roughly about GTX-1070 levels of performance ought to be within reach. And remember, you will have 2 of them.
 
The multicore Geekbench may be comparable but the single threaded performance of the cMP vs. nMP is much lower so if your application can use 12 cores that's fine but if it doesn't scale well over multiple cores then the performance will be way down.
Fair enough, but if you're using one of these machines , chances are you run software that depends on multicore performance anyway. Sometimes you can't have it all.

What about Displayport 1.3/1.4? Does TB3 being enabled for DP1.4 Alt Mode (not merged mode, which supports upto DP1.2).?

I could tell you, but then I'd be giving away Apple's plans for 5k displays. Job preservation mode just kicked in. ;-)

I have to confess, I ever dreamed if the Mac Pro becomes powerful enough I could Dual-Purpose it, as a Number-Cruncher and Stowe ...

Updated processors providing a minimum of 6 cores and a maximum that is not yet set in stone.

Please Wink an Eye to Tim and Ask for E5-2687W and E5-2699 even if means GPU choice restrictions there are people interested on a more powerful CPU option than a more poweful GPU option, you can Offer those monster on a trade not not allowed to mix in CTO with "RX-490" GPUs.

Top card is "RX-490" with DDR5X. This is where the extra power is going. Same graphics form-factor (no standard slots). People - especially anyone wanting to game on a 'pro - are likely to be grumpy about the graphics performance (worse than GTX-1080), but compute performance will be 20-50% better than the present variations.

Earlier AMD Vega (translating which "custom GPU" means), or a Dual Polais 11 GPU on each card (4 Total GPUs).

20% better FP64 compute and 50% better FP32....

A bone will be thrown and two flash drive slots will be available.

A bone, or just an system configuration imposition (since TB3 requires 8PCIE3 lines, to balance the sysem and not leave GPU2 on 4PCIE3 lines you have to put 2 PCIe2 NVMe instead one PCIe3 NVME, also fully re-cycling current GPU/SSD Form-Factor).

Actually, you will be able to put P10 with GDDR5 to 129W thermal design power with lower voltage and 1250 MHz max boost clock. 5.76 TFLOPs of compute power from single GPU, 11.5 TFLOPs total.

I still would prefer Fiji...

There is 6 display output framebuffer, linked with new GPUs in macOS Sierra. So I think there will not be only 4 display outputs, as OP says.
 
RX 490 can be just dual Polaris 10 GPU. This is the biggest possibility currently.
 
With due respect, that's just some unfounded speculation that an over-eager web site whipped up out of nothing.

Said! (I'm gona be your new fan, BTW DarkNetGuy is Fired...)

Another Indirect Leak nMP's "RX490" is an AMD VEGA, this is consistent with the Expected FP64 perfomance.

Maybe, but they have a point.

Only GPUs possible with 9 at the beginning of shipping numbers are the Polaris architecture GPUs.

Vega is completely new architecture. It will be IPv9, Tonga is IPv8, Fiji is IPv8.1, Polaris is... IPv8.2.

Think that new rasteriser or new scheduler would account for new number of architecture.

New architecture GPUs will have new, number scheme.

And RX 490 has two possibilities. It is either new Polaris GPU, or it is dual RX 480 GPU.
 
If Apple really wanted to make waves in the pro market, they would announce updated Open GL & Open CL drivers, the new tower Mac Pro and modern nVidia and AMD pci card choices/support, and Oculous/HTV Vive support at Siggraph in a few weeks. They could even adopt the new i7 line that has up to 10 cores.

I don't need them to "innovate" in some weird way. I just want to stop using Windows.

Apple isn't going to do very much on that list, I'm afraid, though they would love for more people to stop using Windows.

But on the topic of VR, Apple simply must be extremely, albeit very secretly, active. The people there are smart enough to know that VR is one of "the next big things" in computing (a principal other being deep AI, though that will likely be centralized for the time being). Given that, there is no way that they would cede the market to others much less unilaterally support others. They will likely introduce their own headset or be aiming at a better second generation product, to be introduced soon.

The Pro is an ideal core development platform for VR, which is a big reason why it will survive. One could expect a VR production tool for it at some point.

More believable than "No One's" yarn (unfortunately). But hey, maybe No One's strategy was to infuriate an actual insider so much that he'd feel compelled to interject with some facts. :eek:

Just shipping hardware you could credibly call contemporary would be a significant positive development at this point, I guess.

that can be said of most of Apple's recent lineup, single core beating all of the Mac Pros. So either you are better off with a 2013 iMac or Geekbench isn't the final word.

multicore use is hard to quantify and will vary by task within most applications, and many of us have taken our cheese grater Mac Pros past what Apple ever offered. for me it's always been about the money. I just can't justify the price for what the trash cans are. especially as in many cases productivity is better accelerated buy having multiple machines to spread different tasks across.

I look forward to seeing what Apple offers this year, and I realize a big part of the price is Intel charging what it does for a Xeon CPU, I just wonder if we will see a big enough cost to performance bump to justify moving on or if the cMP continues to be a contender with ever newer GPUs and other add-ons and we can just use a Mac Mini or iMac for single core CPU bound tasks.

so if it's only about single core, X5687 Quad core 3.6GHz, should get to around 3000 Geekbench and it can go to 8 cores on a dual socket system. not a bad upgrade for $146
