The *Core i9* 21.5" 4K iMac Apple NEVER sold, is it better than the M1 iMac?

Huge thanks to iFixit for sponsoring today’s video! As usual you can find all the parts and tools you need for an upgrade or repair project at iFixit.com/lukemiani
With the new M1 24 inch iMac here for 2021, I thought it would be worth taking a moment to look back at the old 2019 21.5 inch 4K iMac. Specifically, the old design retains a lot of upgradability that Apple has been getting rid of for years now. The last upgradable iMac can actually be taken quite far, so today I’m going to upgrade a 21.5 inch iMac from the core i3 to a core i9!

Which do you think is a better value? An M1 iMac or one of these 21.5" iMacs with some customizations? Would you put money into RAM or storage upgrades? Would you attempt a Core i9 install?

In hindsight I can't imagine how frustrated Apple's engineers must've been for years when Intel couldn't deliver chips cool enough for their designs and actually receiving flack for it from the public, to the point where they just said fuck it we'll make our own cpu and reprogram our whole os to run on arm, what an apple thing to do

@@swiftrealm as with everything time will tell... apple isnt always right and not always the best when it comes to internal designs (they just make it more eye candy then what its internals could cope with). as an it support engineer, i can tell you how much i hate apple's pre-apple chip internals. people kept praising apple designs without actually realizing how they were internally... constant cleaning/fixing/repairing due to most common issues of over heating caused by the dumbest cooling solutions apple had in mind. all the mac lines suffered thermal issues from the beginning... intel/amd are general use cpus for gazillion hardware combinations... apple's only option was to switch to its own custom cpu. ibm path was stuck, moved to intel, it got stuck... their own design give them a bit more headroom, but we ll see how long it ll take to hit the wall... but at least, now they can control many aspects of the features for their designs... but its not like intel or amd doesnt know how to design cpus, it is unwillingness to design around parts, they want parts designed around their shells/form factors... not always the smartest choice... apple maybe will learn something in the long run about these

Power supply is not a main concern here. The problem is that 21,5 logicboard does have enough VRM phases to handle i9. This would cause extreme temps on VRM section which has no cooling on this logicboard. Using it with i9 CPU in a long run will most likely cause VRM short circuit

[@Bushidounohana]

The power supply risk cannot be overstated. While the process overall is more tenuous than standard PC work, it isn’t necessarily the worst ever. But having had the pleasure of being shocked by a power supply, I’d advise caution for other DIY’ers. My experience was fortunately quite mild and I’ve torn into a few older iMacs, but it stung me bad enough to give me grave respect for it. (I wasn’t doing this upgrade, but rather doing some work on a failed GPU on a 2011 iMac at the time.)

[@NarayananSrinivasan]

Great mod Luke. IMO, most consumers won’t be needing this but would definitely appreciate running the casual iOS and iPadOS games on a big screen like the M1 iMac.

I doubt many will be keeping their M1 products for as long as they could with earlier Macs. The soldered in non replaceable/upgradeable SSDs have a limited lifespan and when the SSD is dead the Apple joy ends. Non upgradeable/replaceable RAM is also a problem. I still have 2009 Mac Pros which have been upgraded to 12-Core 3.46GHz machines with up to 128GB of RAM, modern graphics cards and modern NVMe SSDs. Pre T2 security chip iMacs had upgradeable/replaceable RAM, CPUs and storage which will allow those Macs to potentially last many years longer than current models but that means less money for Apple so....

Is there some reason why you don’t drain the capacitors on the power supply while removing? I work a lot with tube audio equipment which also store huge charges in their filter caps in the power supply sections and generally use a 10k resistor with a length of 14 gauge insulated hookup wire and alligator clips to ground out and thus drain the charge from these caps.

What’s the highest cpu can a 2017 5k iMac use? Can it go higher than a i7 7700k? I have one and wouldn’t mind more power without breaking the bank 😆 thanks

[@mousecursor6521]

Just wear gloves when taking out the power supply!

[@fc-dz4wd]

you are always willing to take on a new challenge, repairs or upgrades, they are great videos, so why not more of them in the future

It's all fun & games until Intel ends up like Cyrix.

Intel already has to licence the x64 architecture from AMD after the Itanium fiasco, and they cross licence various other technologies too. Intel is no longer master and commander of it's own architecture. Every so often, AMD gives Intel a bloody nose as a reminder. ARM slaughtered Intel in the mobile and low power markets, and now Apple makes the M1 ARM that has Intel worried at the higher end. Folks at Intel must be wondering if it can get much worse.

Luke, many many thanks for this. Unfortunately I ordered the wrong memory (I didn't see the 'Show More' so I didn't have the Amazon link). However I reinstalled everything including the original 8Gb RAM (and of course the i9 CPU and all works fine. I had a small difficulty with the top screen connector but that was replaced eventually. Parts left over..... Just one. A rubber tube about 1 cm long which is capable of being slid over a metal mounting in the iMac but which one? I now have everything held together with masking tape awaiting the arrival of the 32Gb with the correct spec before I finally seal up with the adhesive strips. Many thanks for the excellent video and I am of course subscribed. Now to install Monterey!

Crypto is the new gold

[@alipiofrancis8909]

I wanted to trade Crypto but got discouraged by the fluctuations in price

[@zhangwei8890]

That won't bother you if you trade with a professional like Mr Daniel James

[@lawrencelarmour2335]

Yeah, My first investment with Mr Daniel James earned me profit of over $25,530 US dollars, and ever since then he has been delivering

[@user-cq3px5yw4r]

Daniel James has been managing my trade for months and I keep making profits every week, I made $9,130 last week

[@iannicolson]

Is there not any way to safely discharge the power supply? Like what is usually done when servicing CRTs.

[@adamslawson]

Can I put the 6-core i7 that comes with the 2019 21.5" iMac into a 2017 21.5" iMac? I've bought 3 of these 4k 2017/2019 21.5" iMac's lately and wanting to use my leftover parts from my 2019 and put it in my 2017's, upgrading their 4-core i7 to the 6-core i7 that came with my 2019 model. Please help!

[@Space_Mike]

Thanks for the tips! Just finished the install. I like OWCs trainng videos bc I don't read so good. Used the OWC RAM upgrade instructional video, then switched to this video for the CPU stuff. Great channel BTW!

[@seanwhalen5011]

Ive done work on my own 27" Imac and i know the power supplies are dangerous, but as long as I have it unplugged and have pressed the power button and relax I am much less likely to get nervous and mess up and touch it, from my experience.

[@YourPoolHomeRealtor]

Thank you for your info. I have a 21.5 2017 Imac with 3.4 GHz Quad-Core Intel Core i5 4k retina 8 GB of memory with a Radeon Pro 560 4 GB do you think I should supercharge it or buy an M1 iMac New iMac 24" with Retina 4.5K Display - Apple M1 Chip 8-Core CPU, 8-Core GPU - 8GB Memory - 512GB SSD, I was thinking of getting Apple 2020 iMac 27" - Intel Core i5 3.3 GHz - 8GB Memory - 512GB SSD - 4GB Radeon Pro 5300 Graphics since Cosco have it for 16, I do some editing in Imovie for my KZbin channel, what you recommend me to do? I have opened some other iMac to change the memory so I'm not scared of the power supply lmao Thank you for all you do!

[@joseloredo3615]

I'm in the same situation... Wait for the upgrade of iMac 30/32 according with rumors, or just to buy the iMac, 2020, i7, 1Tb. The last iMac that You can upgrade by yourself... 🤔🤯🤔

[@sevagtankabalian91]

I am into upgrading the base model iMacs, i highly appreciate the work you did, it turns out to be the perfect 21 inch iMac every one deserves👌.

[@j_suru-1734]

I have the late 2015 of this exactly the same one and so far there is no fail

[@laneyslaney]

Given that the core i9-9900 is EOL, and not available, what other processors are compatible?

[@AIrecents]

Can you do the same with 2017 21.5” imac? If not, what’s the best cpu you can put into that mac? Thanks

[@danhutchinsonbackup]

The Fusion Drive that my 2015 iMac was SOOOOOO SLOOOOOWWWWWW but I replaced that drive with a 1tb ssd

[@halfawhiteguy3145]

just curious would rubber gloves resolve that whole power supply / shock issue?

[@ChristiandenBoer]

Watching Luke reassemble an iMac is more relaxing a massage 👌🏼

[@Errcyco]

Dope and helpful video dude I appreciate it. Literally no video like this on KZbin from anyone I trust. Thanks again.

[@nedracine5364]

Luke: I am thinking about giving this a shot on my iMac Retina 5K, 27-inch, 2017. I would be replacing a 4.2 GHz Quad-Core Intel Core i7 with 64 GB 2400 MHz DDR4 and a Radeon Pro 580 8 GB GPU. What do you think? Should it work?

[@aleksbush2399]

Hi there! Wow it's a very cool project. I will try to make the same.. the thing I did not get is can I do the same thing with 2017 model, because the specs are the same ?

[@MrAtthedrivein925]

Hi Luke I just wanted to say the production value on all your videos is so excellent, I really enjoy your content.

[@truesightgrabber]

I got same year iMac 2019 27” 9900k but the ram upgrade is accessible from the back plate, way easier than here.
