Video Overview

Introduction

500 nits, 1 billion colors, and two Thunderbolt ports—that's everything, right? Not so fast. Apple already told you about the updated iMac 4K's fancy specs, but we're here to reveal what wasn't in the press release. It's time to take this all-in-one and split it into a whole lotta pieces—join us for a teardown of the mid-2017 iMac 4K.

Can't get enough teardown? Here's where to get more teardown: Follow us on Facebook, Instagram, or Twitter for the latest teardown news.

This teardown is not a repair guide. To repair your iMac Intel 21.5" Retina 4K Display (2017), use our service manual.

Well this exterior certainly isn't giving much away, but you can't always judge a book by the aluminum-and-glass shell of the iMac that you're reading it on. Let's start with what we know: 3.0 GHz quad-core Intel Core i5 (Turbo Boost up to 3.5 GHz)
  • Well this exterior certainly isn't giving much away, but you can't always judge a book by the aluminum-and-glass shell of the iMac that you're reading it on. Let's start with what we know:

    • 3.0 GHz quad-core Intel Core i5 (Turbo Boost up to 3.5 GHz)

    • 8 GB of 2400 MHz DDR4 memory

    • Radeon Pro 555 GPU with 2 GB of VRAM

    • 1 TB (5400-rpm) hard drive

    • 802.11ac Wi-Fi and Bluetooth 4.2

    • 43% brighter display (500 nits) with 4096 × 2304 resolution and P3 wide color gamut

A peek at the back reveals a bevy of ports. First, the usual suspects: a headphone jack, SD card reader, four USB ports, and an ethernet jack. The un-usual suspects? This iMac's sporting two Thunderbolt 3 ports. These support double the bandwidth of the previous generation—each of these ports can push data at 40 Gbps.

    • That's enough throughput to drive four 4K external monitors—although with this hardware configuration, Apple says we're limited to two.

    • How are we supposed to get by with a total of just three 4K displays? How?

  • Confirming our suspicion that this is mostly a 2015 iMac with a facelift, this unit sports the same model number (A1418), but with a new EMC: 3069.

  • We grab our pizza cutter iMac Opening Wheel and go to town. Then, we bring it back home and use it to split open our fancy new iMac.

  • 'Round and 'round we go, and the adhesive securing the display perimeter goes kaput.

    • When Apple introduced this form factor in 2012, replacing the much-loved magnets, we were sad and confused. Since then we've learned its secrets, and now we're on board with how easy this adhesive is to slice through.

      • We'd love to see Apple implement something like this in their other product lines.

  • After a familiar opening procedure, we get our first peek inside.

With all the glass and pixels out of the way, we immediately pick out some subtle updates. First, the logic board has grown—encroaching on territory formerly held down by the right speaker, and even expanding towards the fan a bit. Even more notable, there's a conspicuous heat sink mounting plate sprawled out in the middle of the board. Funny, the old heat sink didn't need one of those...

  • Lastly, near the center of the bottom display bezel, just beneath the glass, there's a microphone! Whose ribbon cable routes right over the top of a screw, which is pretty weird.

Looks like the hard drive has a special bracket, would that likely be included if you BTO a model with SSD only?

JM Palacios - Reply

Well, this part of the refresh is less refreshing than we'd like—the right speaker is no longer immediately removable. It's trapped pretty solidly by the new logic board contours.

The rest of this iMac comes apart pretty much the way we expect, and we dispense with the power supply, hard drive, and fan without fuss. And with a bit more elbow grease, we shimmy  the logic board out of its slot to reveal ... removable RAM? We can hardly believe our eyes.

    • Yep, those are SO-DIMMs. Two of them.

  • Slightly less excitingly, there's also an exciting split heat sink. But seriously look at that RAM!

What's in the bottom-left corner of the mobo? It looks like a mini-pci card; maybe the wi-fi?

  • This new heat sink design has us intrigued. What's hiding under there?

  • Warranty voiding stickers on the heat sink screws? That's odd. Could that mean...

  • Yes! The CPU is modular, too! It lifts right off with the heat sink, revealing a standard LGA 1151 CPU socket.

  • Again, this isn't the most accessible thing in the world—it's flipped onto the backside of the logic board, trapped behind a lot of other components, and buried under a glued-down pane of glass—but for the first time in years it's possible to replace or upgrade the CPU without a reflow station, and that's a big win.

It should be noted that legally, such warranty void stickers are invalid. The Magnusson-Moss Act quite clearly gives users the right to upgrade, fix, and update their machines as they see fit, without voiding any warranty (unless the user, in the act of upgrading itself, breaks something).

This CPU is quite well thermally-pasted into its heat sink; prying it out was surprisingly tough. Someone wants this processor to keep cool. Finally, we're face-to-face with the star of this teardown: an Intel SR32W Core i5-7400 Kaby Lake CPU, 6M Cache, up to 3.50 GHz.

  • Looking at the rest of the Kaby Lake lineup, we're actually not seeing any desktop-class CPUs in a BGA package. Maybe Apple reverted to a socketed CPU because that's all Intel is offering at the moment.

  • But with Apple's clout and famous negotiating skills, you'd think they could get a soldered CPU if they wanted. Plus there's that mysterious modular RAM...

    • Have you been hearing our pleas, Apple?

Yeah I'm guessing Apple is using modular CPUs to save on components. New iMac line? Same thing -- just swap out the CPU! I guess they came to a point where they were losing a lot of cash in repairs.

TheAnimaster - Reply

I think that apple was seeing warranty costs expand for repairs to in warranty devices where the CPU or Ram Failed and the local apple store couldn't fix it and could only give them a "new- refurbished" unit. then the broken one would have to be torn down and sent through the refurb process to sell at a discount. Huge $$ drain on in warranty repairs. So giving a modular design but not easily accessible to commoner allows the local stores to repair these issues. Also apple was seeing a large number of the old "apple" crew that was holding on to their older machines (circa 2010, 2011) and moving up to the current models because it was difficult to justify a machine that you couldn't increase ram when a newer OS version would benefit for the increase ram. Also that apple was getting the jibe of being the new Microsoft/Dell wanna be's (proprietary, not up-gradable, overpriced disposable machines.

Those kinds of slots are very common in server motherboards. They're easier to damage than the flat style but use much less PCB space.

The size of the b/B is important here the small b is bit where as the big B is Byte. 8 bits equal a single Byte

Here's a full chart:

1 byte (B) = 8 bits (b)

1 Kilobyte (K / KB) = 2^10 bytes = 1,024 bytes.

1 Megabyte (M / MB) = 2^20 bytes = 1,048,576 bytes.

1 Gigabyte (G / GB) = 2^30 bytes = 1,073,741,824 bytes.

Previous iMacs featured a dual-mic setup, with two microphones hiding behind the front-facing camera. Two microphones allows the device to filter out ambient noise and produce a cleaner signal. This year, it seems Apple switched to a single microphone—and moved it to the bottom of the display, behind the glass.

Hey Dan, it looks like the foot is not "user-replaceable." The mounting screws on the foot face into the iMac rather than straight up, so they can't be revealed by pivoting the stand around its hinge.

Final Thoughts
  • The CPU and RAM—two of the components you are most likely to upgrade at some point—are both modular.
  • The standard 2.5" SATA hard drive is fully upgradable—though you can't add a blade SSD thanks to an empty pad on the logic board.
  • Cutting the tape to open the iMac isn't too hard (with the right tools), but it must then be replaced to complete any repair.
  • Most replaceable components (like the RAM) are buried behind the logic board, meaning you'll have to take apart most of the iMac just to gain access to them.
  • The glass and Retina Display are fused together, increasing the cost of replacement.

With the modular RAM slots facing the rear of the computer, I'm annoyed (not surprised, though) that Apple didn't put a hatch there so I could upgrade the RAM myself. This is difficult enough that I would just eat the $200 to get 16GB of RAM from the get-go. :-/

omar96 - Reply

So if the RAM is user replacable, it means we can put 32GB instead of the 16GB limit Apple is imposing and could swap the CPU to a i7-7700 (upgrading the CPU is too costly imo ) as all i5s support 32GB.

Why give it better than a 3, iEvan? Putting it on a relative scale would seem to reward mediocrity. It's still really hard to repair since you have to take out the screen and all. 3 is the correct score, compared to the 0 or 1 they'd get if everything were soldered and you couldn't open the thing at all.

mrmacfixit - Reply

The 27-inch versions (except for the upcoming iMac Pro) have user accessible SODIMM slots that you can get to via a little hatch on the back, same as always. Apple doesn't use memory down (soldered to the logic board) configurations indiscriminately. They go that route for mobile platforms for the considerable power / space savings, and I'm pretty sure we've only seen it in desktop models that use mobile U series processors.

repoman27 -

You can also find documentation on Apple's website about RAM upgrades on their iMac. Which is what lead me here in the first place.

They curiously stated the 21.5" 2017 iMac can be returned to Apple or an authorised service centre for RAM upgrades. I suspected that meant socketed RAM which iFixit comfirmed in this teardown. The socketed CPU was a nice surprise though!

@repoman27 and Andrew Curtis.

Thanks for the replies, I guess I was confused by the term "configurable" on both the 21.5 and 27 iMac which usually means that the RAM is soldered. Thanks for the link to HT205040 which I had not seen before.

See above. I think you are doing a great service to the industry. Pls keep it up. And I would love for you to identify the country of origin for all your teardowns. And whether you feel, as I do, that products consumed in North America should be manufactured here. We currently have unacceptable exposure to China for most consumer electronic products from smartphones to X86 Servers. In the event of a conflict in that region we would be unable to get computer products. This comment goes against the grain for the industry, which is very happy they could leverage low cost labor rather than automate production. Plus, most were able to outsource manufacturing to Asian ODM suppliers, not having to make those investments here. On new technology Im working with MIT on a Silicon Photonics project: Future servers will have Tbps lightwave circuitry.

John MacWilliams - Reply

I think you have it all backwards. Without getting too deep into it, I think you blame other countries too much and automation not enough, and I think it's clear that automation has a higher initial investment cost, discouraging some, but that may change. Further, it's not that conflict with China will cut us off from consumer products, but that our interdependence lowers the chance of major conflict occurring in the first place. I understand the desire for protectionism, but not acknowledging the drawbacks of increased consumer prices and lower economic efficiency overall is being dishonest.

US manufacturing can certainly be a good thing, but mandating it via protectionist policy is pretty anti-free market.

What analysis of the connectors is needed? These are standard Intel LGA sockets.

it's not supported but it may be with other cpus. the dependency sits on the CPU side. as far as I remember my classes, it's the frontside bus frequency which decides how fast to interact with the memory level(s).
