Introduction

Bajamos $ 4,999 para tener en nuestras manos el nuevo y mágico Magic Mouse y Magic Keyboard, ¡y Apple fue lo suficientemente generoso como para lanzar un nuevo iMac Pro sin cargo adicional! Desmontémonos y veamos qué lo hace funcionar.

Sepa antes de seguirnos en Facebook, Instagram y [https: / /twitter.com/ifixit|Twitter|new_window=true] para las últimas noticias de desmontaje.

Cette vue éclatée n'est pas un tutoriel de réparation. Pour réparer votre iMac Pro, utilisez notre manuel de réparation.

  1. Nuestro iMac Pro de desmontaje tiene estas especificaciones de "nivel de entrada": Procesador Intel Xeon W de 8 núcleos y 3,2 GHz con Turbo Boost de hasta 4,2 GHz
    • Nuestro iMac Pro de desmontaje tiene estas especificaciones de "nivel de entrada":

    • Procesador Intel Xeon W de 8 núcleos y 3,2 GHz con Turbo Boost de hasta 4,2 GHz

    • 32 GB (4 × 8 GB) de 2.666 MHz DDR4 ECC

    • GPU AMD Radeon Pro Vega 56 con 8 GB de memoria HBM2

    • Volveremos para continuar el desmontaje después de que nos recuperemos de la conmoción y miremos por la ventana en busca de signos de ungulados en el aire.

    • Extrañamente, todavía no hay ninguna provisión-dongle u otra cosa-para usar los Lightning EarPods que obtienes con tu iPhone 7, 8 o X en tu iMac Pro. ¿Parece extraño que estos productos incompatibles provengan, de todos los lugares, de Apple?

    • Despeguemos el elegante envoltorio de tela del iMac Pro y verifiquemos la situación de los puertos ... sólo para estar seguros.

    Every iPhone has an adapter for that headphone jack right there on the back where it always was.

    Devin - Réponse

    Not so, Devin. That adaptor is to plug regular headphones into an iPhone, not Lighting EarPods into a Mac, for example.

    One of the challenges here is that the very very tiny and supremely delicate wire connectors are super easy to damage. Terrible design. Not something I would ever try again.

  6. Las funciones de la tarjeta AirPort se consolidan en la placa principal; por alguna razón desconocida, Apple abandonó la modularidad del modelo 5K. Pero recogimos este innovador clip de retención para los cables coaxiales. La fuente de alimentación se conecta a la placa lógica por medio de no uno, ni dos, sino cuatro terminales brillantes asegurados con tornillos Torx. Este diseño está mucho más cerca de lo que vimos en el Mac Pro 2013 que los conectores de plástico que estamos acostumbrados a arrancar del iMac 5K.

    @sam - Could use a second image showing the other two PS connections to the logic board.

    Dan - Réponse

    Those other two are easy to slide out.

    heywardjr - Réponse

    There are quite a few screws to remove to get the motherboard out. Getting the board out means tilting it to the right as you gentlybslide it out. It tough as the usb and thunderbolt ports are right there. I ended up damaging the ethernet port doing this piece. Would never do this again! I highly recommend not doing this upgrade yourself. I had to take the unit back to the reseller and get it repaired under the $129 extra I paid for accidental damage. This operation completely voids the Apple warranty according to the reseller because you remove the motherboard they will know because of the non Apple ram.

    Heatpipes are on TOP! of thermal block? Half the pipe is cooling the air instead of the processor?!

    Are Apple Engineers mildly stupid or did they have other problems or was this the cheapest solution?

    If you take a look at any good custom CPU-cooler the heat-pipes are touching the Heatspreader directly for a reason.

    • Volviendo al tema de desmontar cosas: el siguiente son estos SSD gemelos.

    • Debajo de un par de pegatinas encontramos algunos tornillos Torx. ¡Se van!

    • Cada cuchilla se denomina Apple EMC 3197, modelo 656-0061A.

    • Apagando los escudos, encontramos algunas fichas:

    • SanDisk SDRQF8DC8-128G (cuatro por tarjeta, dos superiores y dos inferiores, para un total de 512 GB × 2 = 1024 GB)

    • Apple 338S00285

    • A diferencia de un SSD estándar, que tiene la lógica del controlador a bordo, estos módulos de flash en bruto solo tienen un búfer de interfaz: el controlador PCIe / NVMe se encuentra en otro lugar. Más sobre esto en un momento.

    Of course, since there is no SSD controller (see below), you can’t really call these “NVMe SSSDs”. They are flash storage devices, but they only form an “SSD” when connected to the controller, which is part of the T2. And that PCIe bus (assuming it is PCIe), is carrying data between the flash chips and the SSD controller, which means it is definitely not NVMe.

    Looks like this is a new and unique Apple-designed flash memory storage system.

    But one where upgrades could theoretically cost a bit less than normal, since replacement flash boards won’t require SSD controllers (assuming that custom Apple chip isn’t too horribly expensive to reverse engineer, of course).

    shamino - Réponse

    Yes, not a NVMe/PCIe SSD drive! Just the raw flash chips in a frame. The data width is kinda narrow as well…

    Still a very different design than the Function Key MacBook 13” SSD https://d3nevzfk7ii3be.cloudfront.net/ig... It’s design appeared to be a wider PCIe bus (x8).

    So the question is how wide is the I/O here as that will be the limitation of how big the flash unit could be besides the limitation in the physical size. Why would Apple go with such a small footprint unit? At least make the space larger so in the future a larger unit could be put in. There’s doesn’t appear to be space to put a larger unit in

    Dan - Réponse

    Here’s an example of a similar device “Linus TechTips: DIY SSD made of SD Cards!”: https://www.youtube.com/watch?v=3frnBoqq...

    Here it’s using SD cards with a SATA controller. In the case of Apple they are using a PCIe interface via the T2

    Dan - Réponse

    To gain speed beyond what other NVMe/PCIe SSD’s can offer, Apple interleaves across the two flash modules. Think how RAM is interleaved https://en.wikipedia.org/wiki/Interleave... Apple is using the same technique here.

    Dan - Réponse

    Any idea if that flash is MLC or TLC?

Y en el lado opuesto, un procesador Xeon de clase de estación de trabajo, no soldado en su lugar. Es demasiado pronto para decir qué tan factible puede ser una actualización de CPU: parece que el chip está hecho a medida para Apple por Intel.

    An interesting question here related to T2 and the SSDs is why they have the Pericom PCIe mux. It seems from the earlier section that the SSD assemblies are raw flash enclosures, or perhaps at most a custom Apple chip doing Toggle to Flash and PCIe out to the T2. One possibility is that the mux allows for one SSD slot to be unpopulated— if it is empty, the mux configues 2x the PCIe lanes to the T2 from the one populated slot. Another possibility is that mux can re-route the SSDs to the Intel PCH bypassing the T2 under some circumstances. It would be interesting to follow the traces and get the block diagram of the PCH, T2, Pericom mux, and SSDs.

    You guys should let people know not to touch the circuitry of the AC/DC PSU. There is danger in touching certain parts of the internals of PC AC/DC PSUs, even if the PSU has been left alone for a long time the capacitors could still be holding charge. Not only are you showing people how to access the PSU, but you aren’t letting them know to be extremely cautious about handling it.

    • La memoria RAM y la CPU son modulares, lo que significa que las reparaciones y actualizaciones son una opción, a pesar de lo que Apple le diga.
    • Los SSD duales son modulares, pero hechos a medida por Apple, lo que complica el reemplazo.
    • Cortar la cinta para abrir el iMac no es demasiado difícil (con las herramientas adecuadas), pero luego debe reemplazarse para completar cualquier reparación.
    • Los componentes clave reemplazables están enterrados detrás de la placa lógica, lo que requiere un gran desmontaje para el acceso.
    • La pérdida de la compuerta de acceso a la RAM externa hace que las actualizaciones sean mucho más desafiantes en comparación con las iMac 5K de 27 ".
    • La GPU está soldada BGA en su lugar, lo que podría ser un gran inconveniente en una estación de trabajo "pro". No son posibles actualizaciones de gráficos fáciles, por lo tanto, elija su configuración sabiamente.

OOH FIRST COMMENT! either way, Apples getting closer and closer to the point where a mac will literally be one single part that will not be modular in any way.

“ The successor to the T1 chip introduced in 2016's MacBook Pro with Touch Bar, the T2 is tasked here with all the functions of the SMC, image signal processing for the camera, audio control, and SSD controller, and Secure Enclave, and a hardware encryption engine. Whew! “

Meaning that the T1 is controlling how the SSD’s send and receive data and the SSD’s are designed to work with the T1. Mind you that the T1 is an arm based co processor (if I’m not mistaken). They’ll probably do some testing but I would bet that they are not being controlled by an AHCI spec.

First teardown 2018! iFixit Lives!

George A. - Réponse

Each stick of NAND not having an SSD controller validates what I was thinking. Since the T2 houses the SSD controller, calling this a RAID isn't quite right, since each drive doesn't have a controller, it's just one controller looking in two places.

tipoo - Réponse

Think of it more like a bank of RAM. Each operation is bounced between the two modules (inter-leaved)

Dan -

The DIMMs (PC4-2666V-RD1-11) are not DDR4 ECC (Unbufferd) RAM, but DDR4 ECC-Registered ones.

M_Isobe - Réponse

Correct! I think George was joking.

Dan -

Beautiful Teardown.

Tim Asp - Réponse

I really want a iMac Pro but 21” Screen.

K Sec - Réponse

“It’s one SSD controller on two sticks of dumb NAND, no need for a RAID”.

Really? Do you mean that the iMac Pro has 2.8 GB/s read & 3.3 GB/s write without RAID 0? Why not use then a single SSD blade-stick instead if two?

Peter Gamble - Réponse

Think of it more like a bank of RAM. Each operation is bounced between the two modules (inter-leaved)

Dan -

Shouldn’t be much of a surprise that there’s no need for Raid 0 since standard iMac and MacBook Pro have similar Flash speeds also with a single SSD.

MrUNIMOG -

dgramatzki - The speed is much faster for both read & write on the iMac Pro’s SSD setup than what the MacBook Pro’s offer.

Dan -

Is the SSD encryption mandatory? Can it be turned off or disabled? Thanks.

Himm no A10 ARM CPU? Where the rumors false?

Skater Stimm - Réponse

No iPhone APU, but the T2 chip does have a micro-controller (SMC) and also deals with encryption both functions could be run on an ARM based solution.

Dan -

The T2 might have some similarities to the A10, just as the T1 had to the Apple Watch SiPs. Perhaps that’s where the rumors came from.

ymppa - Réponse

2 things. First off, did you guys really not think to try and replace the CPU with a standard Xeon part? Second, has anyone documented the installation of the VESA mount?

Andrew spoelstra - Réponse

If you look at the VESA mount instructions that came with the Apple VESA mount for the iMac 27” 2011 its the exact same part! Apple was roasted on switching out to a fixed foot or fixed VESA mount. It took awhile!

But, I’m thinking if people really need it, one could upgrade their older 27” 2012 > 2017 models using the same parts this model has as it looks like the same mount points. Will need to double check to be sure,

Dan -

Really nothing is “Pro” in this design. Apple learned nothing. They want to continue to sell their super proprietary nonsense hardware. As a pro, you expect easy exchangeable, compatible components, like RAM, CPU, GPU, harddrives, and PCIe-slots, 2 x 16x, etc. In the highest available standards. The new Mac”Pro” just is the new regular iMac. I bet the upcoming MacPro will be a total disaster.

interference - Réponse

“Pro” is not a universal term. For some users, this Mac will be great. For others, not so much. What you want and need isn’t what everyone else wants and needs.

Dongboat -

The numbers tell us it’s a more powerful box than anything Apple has produced so far. So from that perspective it’s a Pro box.

As to being the kind of box a Pro would own that gets into what his/her needs are. This system will serve many pro level user.

It still may not meet the real heavy weight users and clearly it’s a closed system with limited upgradability. That’s where the Mac Pro will be the true expandable system.

I’m hoping we see the AMD ThreadRipper CPU in it! Heavy weight pro’s need lots of threads and PCIe lanes, which is were the ThreadRipper shines!

Dan -

@DAN Threadripper has a TDP of 180W !!

How in the world do you think this will end with the Mac Pro(sumer) if Apple is not willing to cool the Xeon W in the iMac Pro properly!

Glad you guys got it back together! I’d hate to lose a $5K machine for no good reason :/

Liam Powell - Réponse

It’s okay if it’s in the name of SCIENCE!

Kevin Stuckey -

I am curious about the SSD. I don’t like the idea of RAID-0 in a “pro” machine. Double the chance of failure, and a failure of one drive means loss of data on both. I am hoping it can be configured as two separate drives, so I can have half a TB for macOS, and half a TB for Bootcamp/Windows10/Autodesk bloatware like Revit. Curious how the inscription works in Bootcamp too. Does it require some special Windows driver for the T2 SSD controller? Mine arrived today, 2 days early, but I have no time to do more than open the brown box. Which was a mistake, because now I get to look at the picture on the inner box for three days before I can actually set it up. The agony. ;)

Also curious how soon someone with a maxed out machine breaks the screen, writes the whole thing off, and “upgrade CPU and SSD” parts are available second hand. I would assume you could even replace the MB this way to upgrade the GPU as well. It will be a niche market in a niche market, but it WILL be a market.

Gordon Price - Réponse

Please, let is know if you can configure it as two separate SSD.

Peter Gamble -

You could already open another box while writing this.. :D

Igor Leskovar -

It’s not a RAID’ed drive but something similar! Think of it like how RAM inter-leaving works this is who Apple is doing it. Inter-leaving the operations across the two SSD' sets.

As for RAID the type of RAID makes a big difference! As well as what the drives are. Here using SSD’s it’s a lot more reliable than a spinning disk HDD. So if this was a RAID 0 drive I wouldn’t have a problem with it. Then there is Apple’s new file system! Which offers a better write operation so data loss is less likely. We have some large RAID 0 drive sets (all SSD’s) and they are very dependable. Our HDD RAID sets are all RAID 5 and we sync them in pairs to make sure we don’t loose anything.

Frankly, the dependability of your power will be a bigger risk! I hope you have a good back-filling UPS for your new system.

Dan -

Mini U.2 PCIe NVME SSD?

Phy Belong - Réponse

Nope something new! Raw flash inter-leaved. The T2 chip manages the read/write to the modules. If you remember back in the original IBM PC day we press fitted DIP memory into sockets on the logic board. At one point we had stacked chips soldered onto each other! This is in the same approach Apple is using, just within Flash.

Dan -

Here’s a good image of these old stacked chips: https://eda360insider.files.wordpress.co...

Dan -

It is a bit sad to make a ‘PRO’ machine with an underclocked XEON to keep the temps in check.

Form over function rules at Apple

reuze - Réponse

Why do you say that?

Sure the server based chips run faster but at a cost, more power is needed and heat created. The Workstation class chips make sense.

The real question is when does it throttle (load wise). If it doesn’t then Apple has found the sweet spot for this design. So we’ll need to wait for the results from people testing it out.

Sure, I think a lot of people are waiting for the other shoe to drop, the specs of the new Mac Pro!

Dan -

Um, why? How would this be any different than if they had used an overclocked version of a slower chip? The speed is what it is, carefully balanced with other system hardware.

Mark -

“Think of it more like a bank of RAM. Each operation is bounced between the two modules (inter-leaved)”.

Then it is equivalent to RAID 0 in relation to data protection: if one SSD fails, all is lost. Or if the controller chip fails. Or if the main board fails in this case, since the SSD is paired with it. You cannot take the SSD out for troubleshooting or data recovery or booting in other Mac.

Peter Gamble - Réponse

This is no different than with a single-board SSD, not more points of failure than that. This isn’t hard drives where each HDD adds a spinning disk and doubles the risk of failure.

MrUNIMOG -

@dgramatzki

I see a big difference. If data is stripped between two SSD, it is like RAID 0 for data protection by definition.

Peter Gamble -

The data isn’t striped. As already alluded to, that implies to separate controllers on two separate drives. This is one controller accessing chips on two separate boards. As the previous poster pointed out, this would be no different that putting all the chips on a single board, just less flexible in terms of space. which is at a premium inside this enclosure.

Mark -

@mark

You said: "The data isn’t striped. As already alluded to, that implies to separate controllers on two separate drives. This is one controller accessing chips on two separate boards.

Data not stripped on SSD? Do you have a proof of that? How can it achieve 3.3GB/s write and 2.8GB/s read without RAID 0 ?

Anyway, even if data is not striped, do you mean that if one SSD fails, data can be recovered on the other? If not, it is like RAID 0 in relation to data protection.

Peter Gamble -

Interleaved flash is not the same as RAID!

There is no recovery with RAID 0, you’re thinking RAID 1 (mirroring). There is very little risk here, HDD’s are much more prone to failure than SSD’s. In any case you should have a current backup.

Dan -

Miss the “old” Mac Pro 2008-2012. Think what this mac could have been with updated hardware.

I think that Apple does not love companies and "pro". Definitively.

It's like Apple said << Long life to assembled PCs >>. OK. I will buy an assembled PC.

The Outsider - Réponse

All you complainers seem not to have heard that there’s a new Mac Pro coming out some time in the future, explicitly announced by Apple to be modular and upgradeable?

MrUNIMOG -

(i am replying to ‘dgramatzki’ … )

‘The Outsider’ is talking about a beautiful modular design of more than a decade ago…

Since then nothing really happened until that round one came in 2013…

Apple is now so briljant to reinvent a modular system …. again in …. 2018?

yes there is enough to complain…

Randy - Réponse

The old Mac pros had “self contained liquid cooler”.

https://everymac.com/images/other_images...

Christoffer Rasmussen -

Those liquid-cooled Power Mac G5 models were a nightmare. The design put the cooler right over the 1000W power supply. Then the liquid cooler started to leak. This shorted out the power supply, often killing the entire machine. Apple had a replacement program in place that if any sign of leakage was detected, they would replace the entire unit whether the customer wanted to or not. The best part was this was in the middle of the transition from PPC to Intel, so most of the customers’ pro applications were useless on the Intel Mac Pro. It was a total disaster. Liquid cooling is not a good idea in a computer case this small with a power supply this small.

Travis Funk -

As a holdout waiting for a replacement for my 2010 Mac Pro Tower I’m saddened that this all in one because I’ve have iMacs sitting in boxes because the screens were cooked along with some of the internals. My Tower has gone through 3 monitors over the years that I cheaply replaced.

wahakaa - Réponse

Uh, every one of those iMacs can be repaired. What site are you on again?

Mark -

Great teardown and review.

In summary:

- One can upgrade RAM later on - saving a lot of $$ up-front. I got mine w/ 64GB - which should suffice until then.

- GPU does not matter, this one is “good enough” to be considered Pro workstation. Nothing stops one from adding another GPU via Thunderbolt 3 to PCI-e making it actually quite upgradeable (prosumers of this type of device already have a ton of storage via Thunderbolt on their desk, adding another box w/ a GPU is not a big deal)

- CPU is actually upgradeable. Sure, someone’s yet to test this but I am 99.9999% certain this is the case, so down the line in 2-3 years, pop it open, add a new-er xeon in and voila.

All in all - awesome machine. It actually replaced my whole VMware LAB, as I can now run it all on this iMac, in Fusion.

Petar Smilajkov - Réponse

Just looking at the CPU speeds on the Apple site. As mentioned here, the 8 core is not the same part available to anyone from intel. It is slower. The 10 core is also slower. But the 14 and 18 core chips Apple use match the speed of what intel has on their site. The faster 8 and 10 as well as the same speed 14 and 18 all run at the same 140 Watt Total Design Power. Thus Apple may not be using the lower speed 8 and 10 core to save on heat. Apple likely has to deal with the 140W TDP of the 14 and 18.

Perhaps Apple are saving money by buying the 8/10 core chips from intel that don’t pass the first test?

Kemal NottaTurk - Réponse

It would seem that way, until you consider the cache sizes.

Apple has a much bigger L3 caches than Intel offers in their Xeon Ws.

Aweizd Zsakul -

Thanks guys, What a wonderful teardown of the iMac Pro 2018. The pictures and the read was spot on and surely worth the time spent. I appreciate now, knowing what I buy, before I put down the money, and my late 2011 27” iMac needs a new partner this year.

I have planned to upgrade the memory and the SSD, but it is for sure a much greater job than upgrading the 2011 iMac. Armed with the ifixit teardown it’s time to prepare the action.

Steen Ricks Olsen - Réponse

500W is far too little to host a full-fledged Xeon W and a Vega 56. I think Apple relies on thermal throttling and underclocking so performance doesn’t get “too high”. How will it ever support 18 FRICKIN’ CORES and a VEGA 64?!

Ntuthuko Zimu - Réponse

In this configuration (motherboard to be vertical once re-assembled), would liquid metal thermal “paste” accumulate and drip down to other parts of the motherboard over time due to constant heat and gravity?

Jeff Suovanen -

Technically, you could add multiple external GPUs for upgrades through the thunderbolt 3 ports

Lucas 9810 - Réponse

I think Time Machine renders all of these arguments about RAID 0 and interleaving flash modules moot. For ~$100 I can have a living copy of my data that can easily be recovered to another Mac, or simply browsed by another Mac or PC with little effort. I leave a 4TB drive hanging off of my iMac 5k at all times for very little cost to me. The backup drive and the iMac are on their own over-sized UPS. All of that cost me about an extra $250. Why are you all worried about data recovery when some simple backup discipline would solve all of those problems. If you’re really a “Pro” it seems to me that you should have multiple contingencies around data loss and in the unlikely event of flash failure, you’d be fine.
