Keep in mind that even the standard iMacs from 2017 support external GPUs now, so that part of the "upgrading" is not really an issue.
 
How on earth can they not have all the models ready to purchase now? Why are there all these delays at apple?

The delays are probably with Intel (again), though to be fair to Intel, these are evidently custom W-Series CPUs with much larger L3 caches (and lower base clock speeds).


Does this mean you can't open it by removing the screen? The RAM is indeed socketed, so it should be upgradable..

Yes you can remove the screen and logic board to access the RAM (and probably the SSDs, as well). Not something individual owners will likely want to do, but for a large site with trained IT support staff, likely not a major deal.

There are better specs. Just go look at AMD Threadripper. And the usage doesn't matter. It's a computer. They're all meant to crunch numbers fast. Don't kid yourself if you think because it's got an Apple logo on it, it does things differently.

macOS is different, not just in GUI & kernel, but also in how Apple optimizes hardware usage. ie architecture

Typically Windows has a 20~35% performance penalty for same hardware due to its open upgradable nature. But not always. And no, I'm not digging up benchmarks. My statements are based on life/work/office/studio experience. As someone who is both a creative and a hardware/os/app fixer/dev who started w/ IRIX(unix) and DOS.

My main gripes w/ Apple are how far behind the curve they've been in terms of expandability and hardware choice. As in, no real Mac Pro update since 2010. But now that we have TB3, external enclosures are more of an option; however, I still want a box w/ built-in standard PCIe slots to enable full performance and acceleration.

Sure the iMac pro was four TB3 ports, but likely only two controllers. Thus one can only add two external devices that require full bandwidth, or less when adding additional monitors. Basically pick Two: eGPU, RAID, Red Rocket-X, Display 2, Display 3, External reference Video single chain output, Live stream video input

Last time I checked the Threadripper was just a bit faster than a 10-core Skylake design, and that only in massively parallelised workflows. In other tasks, it is slower than a quad-core Skylake. I am sure that the 18-core Xeon will be significantly faster than any CPU AMD can offer, if you need that kind of power.

Please, lets no go there. What you say is false, simply and clearly. Yes, there are some things on the core OS level that make some stuff faster on Mac and some stuff faster on Windows. But for most, there is no difference (except actually Windows has an edge in things like network). And of course, graphics — Windows drivers for GPUs are simply "better", because thats where the money is at.

I am sure that the cause of your observation is a different one. It is much easier to write high-performing client software for Mac, simply because Apple gives you all these great programming libraries. They even come with a hand-written (by very smart people) set of machine learning algorithms and other goodies. As a Mac developer, you can easily offload your work to other cores, use the standard OS features that are optimally coded, and enjoy the benefits. Most Windows applications don't go that far. So you get ugly and awkward software.
 
In My opinion, I think your statement is rather foolish. Because ultimately the user is going to purchase the specific iMac knowing exactly what they need it for. They're not thinking about what Apple may or may not do in the future, they're thinking about how this machine can advance their prodcutivity they currently need in the moment.

Conversely, it's like picking what comes closest to what you want. Knowing that it can't do the job as required. Since none of the options are fantastic at this point. IF your inclined to stay with the Apple ecosystem. As someone else said, I hope they do a better job on the next "Mac Pro". This machine is not that advantageous from a professional point of view. Not very upgradeable, nor is it easily serviced ... one problem and it ALL goes in for repair. And than you wait ....
 
Programmed obsolescence. All-in-one (AIO) computers like iMac are a huge aggression to planet Earth. Computers may last for seven years or less, whereas displays may last for more than 20 years. I am using an Apple Cinema Display 22-inch purchased almost 18 years ago and it works great. And it has been on an average of 15 hours a day, 356 days each year.
 
Does anyone know what kind of Geekbench numbers the base model puts out? I am currently using a late 2012 (first slim model) 3.4 i7 and can see the base as being a good replacement. I’m pretty sure even the base will be pretty damn futureproof?
 
Tempted to sell a touch of BTC to pick one of these bad boys up.

Won’t do it ... but I’d be lying if I said the temptation wasn’t there. ;)

I'm probably wrong in my assumption but in terms of the RAM I'd imagine you *might* be able to upgrade it at a later date if you visit an Apple or Apple Authorised store like some of the current 21.5" models.
 
£5000 for a machine where you can't upgrade the RAM.

My.
Sides.
[doublepost=1513103096][/doublepost]Sooo.... on a completely unrelated note, the base model HP Z6 comes with a 10 core Xeon, 48gb RAM and an 8gb Nvidia Quadro for under £3500.

And you can put in another CPU if you want.
And you can expand it to terrabytes worth of RAM.
And it is probably the most expandable ready-built PC that has ever been made.
And it looks nice.

But I know - all this is as nothing to whatever cute new little feature macOS will give you next.

Ram not even upgradeable? Thats brutal.
It's a goddamn joke is what it is.

Cue in obligatory Steve Ballmer quote on the iPhone iMac Pro:

"There's no chance that the iPhone iMac Pro is going to get any significant market share. No chance. It's a $5000 subsidized item. They may make a lot of money.
...
5000 dollars? I said that is the most expensive phone iMac in the world. And it doesn't appeal to business customers because it doesn't have a keyboard Touch Screen. Which makes it not a very good email Windows 10 Pro machine. ... Right now, we're selling millions and millions and millions 100s and 100s and 100s of phones Surface Studios a year. Apple is selling zero phones iMac Pros a year. In six months, they'll have the most expensive phone iMac Pro by far ever in the marketplace."
:p

Love the quote in that Brownlee video;

'Its pretty much the ultimate YouTuber workstation...'

I had to hold back a laugh.

Zbrush? Substance Painter? VRay? Unreal Engine? Anyone?

When are we going to see a professional review by someone whose profession is not reviewing Apple products?
 
I frequently fix every Mac Apple has released in the last decade. Some are more difficult then others. And sometimes its cheaper to pay Apple to fix it.
But it seems you can't rely on Apple to fix things if they make them obsolete after 5 years (or is it 7?). If I hadn't been able to pull the guts out of my Cube so easily and fix it myself, I don't think I would have had any recourse sending it into Apple. It's 17 years old.

When professionals want to upgrade, they drop in the new machine and go. They don't spend downtime fiddling with the innards.
