IMHO i say the iMac Pro due to its workstation/server class HW should, should go into the Mac Pro section of the MR forum

no offence to the iMac Guys but most of them wont know about such Hardware like what an RDIMM is.... where as a good few people here due to the nature of the Mac Pro will know what an RDIMM is for example

(I aint endorsing the iMac Pro BTW, id say its Cube 3.0 with a 5K screen stuck on, but that would be rude to the cube, at least the G4 cube had a decent upgrade path and you could easily get to the guts of the thing, nothing like fitting Dual 2Ghz 7448s into a machine that shipped with a 450Mhz 7400 originally :D )

Nice improvement since 2013! You guys rending garments and gnashing teeth yet? :D

I notice none of the reviews have mentioned noise level / throttling under heavy load. Wonder how many eGPUs it supports?

it has Dual thunderbolt 3 controllers im pretty sure, so I would say 2 eGPUs should be possible

...and due to its tragic lack of being upgradeable - it belongs in the Imac forum.

if we go with that logic shouldn't the Trash can Mac Pro go there as well then?

because from late 2006 (the 24 inch polly carb), to 2011 most iMacs had not only upgradable user accessible RAM, the CPU was socketed, and even the GPU was in an industry standard MXM form factor, many people have upgraded iMac GPUs. which is more then what the trash can and iMac Pro have :)

The problem with the iMac forum is that there is an incredible amount of noise to information ratio. It's like reading YouTube comments.

While AidenShaw has a point about posting in the right sections, I just know how incredibly hard it would be to discuss something on a somewhat informed level over there.

It would probably help to have a iMac Pro forum. Let's see if the price tag of $5000 auto filters some of the noise.

Because we all know, if you pay $5k+ for a computer, you're not full of it.:rolleyes:

TBH, from this chart, I suspect the test is single thread limiting. Otherwise, how can a Quad cores MacBook Pro faster than a 20 cores Linux Server, even the CPU is getting faster and faster, but definitely not 5x faster from E5-2680V2 to 6700HQ.

No, but because no one should pay $5k for an all in one, unless they have really good reason to do so. And if someone decides to spend the money, or is seriously considering it, I would assume the discussions those guys/gals are interested in are more 'on topic' regarding pros and cons relative to the iMac Pros intended purpose. That would also be the reason why I phrased it "Let's see…". An expression of "hope", if you will.

The Mac Pro forum certainly isn't free from mud slinging and dick measuring. But it's still night and day when I compare to other parts of the macrumors' forum hierarchy.

I'd be happy if I didn't have to read every knee jerk reaction to the iMac Pro from people who never intend to buy it.

looks like a completely different GPU? 1.3ghz v 1.6ghz 8gbvram v 16 gbvram

it's early days and lots of the testes my be explained by faster drives and not using a 8 year old GPU :D, there cheery picked as always.

as for what forum idk maybe when apple brings out the new new macpro we will forget about the imac :eek: or not :D
i never spend that much time in the special interest sections.

Well, I don't think anyone expects the iMac Pro Vega 64 to run the same speeds as PC cards?

Same goes for the CPUs. Everything is throttled, or let's just say tailored, for the iMac Pro's thermal spec.

Nail on head. The Pro 580 in a top spec iMac 27" can't match an RX580 in a 4,1 or 5,1 for the same reasons. But that figure, as nice as it is for the 5,1, does not tell the whole story. CPU multicore score for a 10 core iMP is around 50% better than the 12 core 5,1s (the real 5,1s, not all the Hackintoshes in the chart). Then there's the SSD performance, the nice display…
Hopefully, these figures are a positive statement about what we can expect from MP 7,1. Apple isn't going to want to sell iMP to anyone if they can upsell....

kinda makes you wonder what they'd have had to do to the design to build it around a standard desktop GPU and non-throttled CPU, while still being an AIO form factor, and whether anyone would choose not to buy one because of that.

But, Apple has long since lost track of the Modernist ethos of beauty being inherent to the design of anything that is functional, and they're in full-on PoMo "design is how it looks" ornamentation, so throttling it is.
 
The iMac Pro and Mac Pro share a similar user base and therefore I would expect many users of either one to cross shop the other. It seems completely reasonable to discuss one in the forum for the other. Especially when the iMac Pro is likely to take the throne as the fastest Mac (until the new Mac Pro is released).

Question: for a CPU whose base clock speed is 3.0 (or 3.3) GHz with turbo boost to 4.5 GHz, what speed does it actually run for the benchmarking program? All iMac Pro CPUs can be turbo boosted to 4.5 GHz (am I right?). Does that mean they are basically the same when running programs (including benchmark programs) that are single-threaded (until the system cannot handle the heat)?

I am asking this because most of my work is multi-threaded, as are most modern programs. However, there is one single software that I often use is notorious for its multi-thread performance: Photoshop. So I am struggling with whether I should go for the 14/18-core versions whose base speed is low, or the 8/10-core versions with high base speed.

Any insights/suggestions?

Yes - but there's some confusion in your statement. Assuming that the system has reasonable cooling (perhaps not a good assumption for an Imac) a single thread will never "not be able to handle the heat". All single-threaded apps should sit at the turbo speed start to finish unless the thermal system is way, way weak.
 
Thanks. I have iMac Pro in mind in particular. But I guess we will never know about its cooling until people start to have the actual machines in hand. (So far, based on those previews, it seems fine. At least, no one complained about the cooling.)

So based on what you said, I should to go for more cores, rather than worrying about the base clock speed. Now it's time to check my bank account....
 
Maybe it's sour grapes, but I look at the numbers, and think to my self...

"Awesome! My 5 year-old 5,1 3.46 with a MVC 7970 is still in the ballpark with the new $5,000 beast!" Now if my 30" ACD will just give me a few more years...

I'm not making a living by my computer's speed, mind you. My teenage daughter did come to me the other day and tell me that she noticed my computer is quite a bit slower editing 4K video than it was with 1080 video. I told her to start saving up. :rolleyes:

they will chose a cpu/gpu skew that fits the thermal envelope of the computer, it will boost till it gets to hot.
the heat sink will be able to dissipate x heat at a time so it will go at max speed till the heat sink cant cope, so it will relay depend on workloads i gess, with GPU+CPU at max it will down clock after x time.
on intels part they have piles of skews so id gess it's a off the shelf part the GPU may be custom as ATI seem to do that for apple
