The machine sounds awesome, until you a) see the price... starting at 5000$... with hardware specs that are not even close to what you get with 5000$ invested into PC DIY gear... b) you realize again, this machine will most probably be damn hard to upgrade. And c) you start to ask how hot the components will run in an AiO chassis.
I hope I am wrong on my second and third complaint and Apple for once has NOT made their machine so thin it boggles the mind, instead concentrated on thermals and upgradeability and made the machine thick enough and the hardware exchangeable. Given its a Pro labelled machine, and none of the components in it probably come in a laptop friendly formfactor, nor are easy to cool within a laptop chassis, I guess this will be a monstrous thick iMac (which certainly will put some weird people off... whats it with this craze for ever thinner machines, especially for AiO you NEVER even put into a backpack, is beyond me).
That still leaves the price. The only thing this machine has going for it is looks (and given it will not be a superthin iMac, it might not appeal to the usual remaining Apple crowd amongst the graphics artists), build quality (which arguably you can also have elsewhere nowadays, still Apple usually does not skimp on that), and MacOS.
With only the last one being an Apple exclusive...
Ehhhh... I guess its a weird mixture between two extremes that might ONLY find a moderate fanbase because Apple is dragging their feet with the Mac Pro. Which, given its not another waste bucket of doom, is the only sane options for Apple Fans needing Pro grade power. Because a full sized tower guarantees good thermals, and upgradeability, whereas this AiO needs a lot of engineering marvels to give even a fraction of that.
On the other hand, if you neither need the upgradeability nor the powerful components running at max output (instead of constant throtteling, which still might happen in an AiO even with the fattest panel ever, see dells Workstation AiO), and are too smug on the design of their workstation to accept a tower standing next to their desks, why pay so much and still make compromises on the design aspect when a normal iMac most probably will also do?
I feel, like the dell AiO workstation, this is a weird hybrid that in the end will not satisfy anyone really.
Apple claims that a similar specced machine on the market without a 5k display would cost about $7000. Is this true? And I guess, since @[member='Hodgman'], mentioned it, are those specs really that out of this world, in most people's opinions?
Well, if you buy the pro grade hardware you usually do pay a premium.
But: A similar specced machine costing more than this = bullshit! I have to ever see the Apple computer which is cheaper than a similar specced DIY Workstation. Even a lot of pro grade pre-builts are cheaper than Apples Pro grade Macs, and none of the builders that outfit machines with Xeons, Quadros and Firepros ever sells them cheaply. To be fair, many of those also have better support as part of the deal (don't know about Apple here).
I am sure you CAN find a shady workstation outfitter that charges even more outrageous prices than Apple... which might is what Apple meant with their words here. Still, in general I call bullshit on that.
with the caveat that we don't really know much about the VEGA GPUs... if these are Pro grade cards with optimized drivers that work with pro grade apps, AND the Vega performance is up there with the GTX 1080 Ti, such a Quadro alone costs 5000$... that could be what Apple means. Because as of now, Firepros from AMD hardly are used anymore in the Workstation space, and with the outrageous prices of Quadros, AMD might undercut them considerably with their newer Pro GPUs. Comparing a 2000$ Pro Grade Vega to a 5000$ Quadro might make the 5000$ to 7000$ comparison more believable.
And then there is the question: do you NEED Xeons, ECC RAM and Pro grade GPUs in a world where ECC RAM has dubious advantages outside of the server space, and Pro grade GPUs only really give you advantages in a select few pro applications (while others, like ZBrush, clearly do not take advantage of it) and more VRAM?
In a world where, thanks to renewed competition, Intel HAS to release an 18 core i9 instead of selling it at many times the price as a Xeon? Where you can get a Ryzen Threadripper with 16 cores for outrageously low prices of under 1000$? Where high end gaming GPUs often run circles around pro grade GPUs costing 6x as much?
I mean, if you can afford a 10'000$ machine, actually NEED the speedup in CAD applications the Pro Grade GPUs bring, all the VRAM you can get, and the maximum amount of cores money can buy, there is no way around Xeons and Quadros / Firepros.
It's clear that by now, the usual 3D artist does not need that any longer. Some CAD folks doing insane stuff maybe. A game artist? Give me a break. Sure, if money is no objection, get that 5000$+ machine... at that point thought, you are rather looking at a a 10'000$ machine, because what you get for 5000$ in pro grade hardware is actually fairly weak compared to a decent gaming PC.
If you have a limited budget, get an enthusiast (HEDT seems to be the newterm coined for that) grade platform, one of the new i9 from Intel which hopefully come down in price a lot, or even better a Ryzen Threadripper, get as much cheap and fast DDR4 RAM you can get and don't worry about the missing ECC, get the fastest gaming GPU money can buy and have a machine that most probably will run circles around the 5000$ pro grade workstation when it comes to raw power for about 2000-3000$... sure, a good screen might set you back another 1000$. Still a faster machine overall. Because a 16 or 18 core Xeon will most probably cost you 4000$ alone. So does a Pro grade GPU on par with the best gaming GPUs on the market. That 4000$ spent on a good HEDT/Enthusiast PC and a good Screen will compete with 10'000$ in pro grade hardware when it comes to raw power.
So really, a Mac Pro or this hybrid will never be good value. Because Pro grade hardware never is. Its not its reason d'etre. Pro grade hardware is there to let you squeeze out the last drop of performance from pro grade applications optimized for it, no matter the cost. If you are on a budget, don't bother, unless you have a very specific use case in mind (I am sure there are reasons some people buy small Quadro cards with 384 CUDA cores for prices that would net you a GTX 1070... I am not so sure I understand the reasons, but I am sure they are there :P)
Oh, and about the "out of this world" part.... does this machine come with motherboards capable of housing multiple CPUs? Multi GPU? Probably not... thus clearly inferior to even the waste bucket of doom Mac Pro already when it comes to top end configs.
Then there is the problem that nobody knows yet how powerful Vega will be... on the theoretical TFLOPS side it looks good compared to Nvidias Pascal, but then that architecture is already a year old and will soon be replaced with a newer generation. And given how underwhelming Pascal was for a double node shrink, how little was changed compared to Maxwell architecture wise (which WAS a good architecture for gaming GPUs), and how small the dies for Pascal where (hey, it was a new node, so no point in rocking the boat too much I guess), there is a LOT of knobs Nvidia can turn up to 11 to make Volta completly destroy Vega (and their own Pascal architecture in turn).
But Volta is still a year out, so lets ignore that for now. Expectations for real world performance of Vega (which for AMD GPUs in the last year usually was far worse than Nvidia, with a 5,5 TFLOPS RX480 just about on par with a 3,5 TFLOPS GTX970) vary from that thing being on par with the GTX 1080 Ti (which has similar TFLOPS, about 1 less than the pro grade Vega already anounced, so quite achievable even with the Vega archtecture still not catching up with Pascal in bringing its raw power on the road), to the best Vega chip only being about as powerful as a GTX 1070 (with the Vega demo on the Computex only fueling suspicions that AMD tries to keep quite about it because it might not be all that hot on performance)
Given that the GTX 1070 still is plenty fast, maybe not enough for AAA gaming at 4k or 5k, still more than enough for 3D applications and compute, and the top end Vega being said to have 16 GB of fast HBM VRAM, that still makes it plenty fast, especially if this REALLY is a Pro grade card with pro grade drivers the pro applications optimize for (which has to be seen. Is it a Firepro card?)
