You heard wrong. The videos I’ve seen that have run these kinds of test only reached ~40c so nowhere near what you have mentioned
The 80 - 90 deg C were referring to the internal CPU temp. sensor, at least for the YT videos that I watched. But yeah, at the external case, temp. measured were in the (low, IIRC) 40s C.

I saw a yt video comparing an Intel Mac to a M1 MBA in which the poster was using an IR function on his phone to show heat. He ran one of those high-load image generator/manipulation app and Air got pretty hot. I think he said something like 80°C, which is close to where you get actual burns. I might have heard wrong, though.
I know Max Tech has done that in several videos, and even the M1 Air was noticeably cooler than any Intel-based Mac under heavy load. They also used an IR thermometer that plugged into the phone rather than something that used the iPhone's cameras to detect heat, so their results may have been more accurate.

Wasn't the reason Apple made the T1 and T2 because unlike the Apple SoCs, Intel CPUs didn't have the Secure Enclave? Why would Apple need to integrate the function of the T2 coprocessor when it's something that's been integrated into Apple SoCs since the A8?
The T2 has other functions besides the Secure Enclave like a SSD controller. It is also highly involved in the secure boot process. Those T2 functions are part of the M1 now.

You can find the list of things that a T2 does here: Apple T2.

Except in this thread we’ve been told the M1 and A14 actually have different cores!
One thing to note is that the A14 CPU cores were designed with desktop MacOS in mind. They implement functions that will not do anything on iOS like total store ordering (TSO) which is used by Rosetta 2 to translate x86-64 to Arm64 and a hypervisor for virtualization. These are disabled at boot and are only useful for MacOS.

It is kind of irrelevant if the M1 is a A14X or not because Apple designed the cores in the A14 for the Mac anyway. The M1 is in no way just a repurposed iPad chip.

As far as I'm aware, the SSD controller has been part of the A-series SoC since at least A12. Apple moved from eMMC to PCI Express NAND flash on the A9 so I actually wouldn't be surprised if the SSD controller has been part of the SoC since then.

Honestly, all those functions mentioned for the T2 have been native to A-series for a while. Mind, from that article, the T2 doesn't contain the SSD controller. It just handles on-the-fly SSD encryption/decryption.

Sure and secure boot hasn’t changed on iOS either. But this is what people mean when they say Apple moved the T2 to inside the M1. It isn’t necessarily new on Apple silicon but it is definitely more than just the Secure Enclave.

I’ve been a Mac user since the mid 80s. Bought my first own Mac 1994. I’ve had wows before (my Pismo and OG iMac comes to mind) and I went through the shift to Intel with its ups and downs. I got tired of my slow and cumbersome work issued PC yesterday and decided that I’ll fix the problem that IT can’t, so I swiped my company card on a base M1 Air.

Since I’m not new to this game, and use Macs at home (current machine is a MBP 15” 2017), I did realise that the M1 is something special. Read the reviews and threads. But boy did this machine wow me.

After one day(!) I can say that this is the biggest leap I’ve experienced. I used non-optimized apps all day today like Dropbox, Onedrive and Teams, that I’ve heard works bad for now, I can’t even tell.

No “I have to give a new Mac a day to settle before I can get full battery life and the fan stops blasting while Spotlight indexes”. It just works out of the box. Silent. Powerful. Fast. Drama free. Incredible battery life, for once a true leap forward. And cheap! It’s probably three times as fast as my work PC, battery life is at least 10(!) hours longer lasting, while costing the same.

I’m super impressed. Nothing is perfect of course, but this time the hype is real.

I’ll probably sell my own 2017 15” Pro now before it loses all of its value and replace it with a M1 Air.

So long Intel! Thanks for everything, but as we all know, nothing lasts forever.

Yes, though that does seem to support the idea that (at least insofar as the CPU cores are concerned) the A14 could be considered the ‘base’ version of the M1/‘jade’ series of SOCs.

its fast for sure but what i like the most is that it doesn't get hot and the fans only turn on when needed. It seems like my mac has never been on at all
Agreed, the thing that annoyed me the most with my work PC was the constant fan noise and heat, just from running Outlook, Word, Excel, anti-virus and a few Edge tabs.

The M1 Air doesn’t even have a fan of course, so that issue is not there. But fanless computers is nothing new.

What impressed me a lot is that I can push this machine to where my work PC would spin full blast AND throttle. No such thing with the Air and my workflow. It’s cool to the touch, even when I try my worst case scenario workflow.

And it was 31 degrees C yesterday and about the same at the office since Greta AC-shamed all of Sweden.

I feel like a total Apple sheep writing this. But this computer no matter what it says on the lid is for me and my workflow a revolution.

This is ridiculous. I did read the reviews, but was like "ok, Safari is always snappier, sure". But this feels like iOS felt for the first time when coming from a slow Nokia interface.

Got a Mini (8/256), coming from a 2020 13'' Pro 16/1TB. Connected to an Ultrafine 5k. Macbook was always struggling with the 5k display, even moving windows around too fast resulted in audible vents. Half screen Google Maps and the laptop was on the verge of death.

With M1, nothing. Dead quiet. Cold to the touch. Scrolling the timeline in Google Photos full screen 5k is smooth as butter with tens of thousands of photos. This was always like 2fps on the 2020 i5 Intel.

Compatibility wise I was afraid important stuff wouldn't work, read some reviews about Dropbox not working. Well, everything works, except some kinks with the Ultrafine monitor not showing resolution correctly, but it appears to be working in 5k actually.

For me this is much more about the smooth interface experience and comfortable operations than some sheer benchmarks.

Apple really did something truly great here.
I've got a MacBook Air M1 and MSI Modern and MSI is faster. So idk…

I've got no such problem with my work PC. If you have a meeting ask the team leader to get new PCs.

Thing is, it’s the M1 SoC that’s the difference, not Windows or MacOS, Lenovo or Apple. We used Macs and PCs in a mixed environment for over a decade. The Macs would fan a lot too, although not as bad as the PCs.

My personal 2017 MBP 15” is quite hot and noisy too, probably on par with the equivalent PC.

What work do you do?
I'm a COO and a senior project manager. Just regular office work. Office 365, Outlook, Word, Excel. CRM system, internal systems. All work is kept in Onedrive. I use Acrobat Pro a lot. Citrix Workspace. Sharepoint. Nothing really taxing like media content creation. The O365/Azure/Onedrive integration is great on my PC, it's just slow.

As an example, one small thing that I and I guess many working in Outlook do many many times each day is switch between mail and calendar in Outlook. On my PC it takes 2 - 5 seconds each time, sometimes even longer. On the M1 it's instant, on any Mac it's usually faster. It's a small thing - but over a day, a week, a decade spent in Outlook, it tallies up, both in time lost and irritation gained. :)

I know what you're aiming at - and I agree, it is solvable, it's not the end of the world, PCs are not useless, and that's NOT what I'm saying at all.

I was just trying to express how big a difference M1 is, especially for what it is considering price and ease of deployment. It IS a leap forward, that for once is accessible for basically anybody and I'll probably not die alone on that hill for sure.

First of all, I dislike Citrix so much, you have no idea how much I dislike it, but I work in IT Support and we give IT Support to many companies and I use Office apps as well, including SCCM and other apps + Windows server and I don't really have such problems. Switching between Outlook's calendar and Mail is instant and the computer doesn't make any. noise either. We also have new PCs but I remember we used to have older PCs and those were a bit sluggish.
I also use Azure AD a lot and really I've never had any problems. I also have MSI PC and it works just fine and I'm ashamed to admit it, but it's faster than my M1 MacBook Air and it can run games etc. The only awful thing about my MSI is the build quality + their customer service.
My MacBook Air with 8GB of RAM isn't slow either and I can do coding on it and run simulators etc. Everything works fine for me. The only computer I've had problems with was MacBook Pro mid 2010 but I used it for 10 years before I upgraded to M1 MacBook Air. At some point PCs or Macs get old.

On a positive note; I still kind of use my iPad mini 2 and I dont feel like I need a new tablet.:)

you should thank your work for the extraordinary laptop. I myself have 3 x86 laptops (2 personal, 1 work) and 3 previous sent to the bone yard. These X86 Laptops get hot. You hear the fan kicking on and running. Work with the on your lap and you’ll get a better idea. My MBA M1 does neither of these. It’s ability to stay cool to very localized warm-ish is outstanding. The performance of these MBA M1s is very very good.

And just to add to this being a M1 thing, not a PC vs. Mac thing, I'm typing this on my personal MBP 2017 15". It's running Safari, Mail, Calendar and Messages. The top part above the Touch Bar is warm, close to hot. The base is warm, I would not like to have it on my lap for more than a few minutes or I would be very sweaty and sticky.

Beside me is my M1 Air, running Safari, Word, Excel, Outlook, Mail, Calendar, Acrobat Pro and Teams. It's cool to the touch, just as an iPad or if it was off. Can't tell if it's on or not.

A bit of an off topic, but I am lucky, because at my work place they listen to the employees and there are also boxes where you can drop anonymous feedback about the managers. I've never worked at such place before, so I definitely got lucky there and if the majority of the employees vote for new computers then we get them. I just consider myself lucky then.

The biggest change for me coming from 16" to the M1 is definitely the temps, either connected via external monitor or doing a video call with a camera on Teams the temps never go above 45-51c.. I suffered a lot with my 16" on this front and I'm very very happy to see that it works well.

Battery life is absolutely amazing even using Teams, honestly if I didn't use Teams at all this thing would definitely 14-15 hours of Screen on Time

You have “several” m1s and they get “very hot”? Send them back, maybe you got defective ones? (not sure why, given a quick glance at you previous posts, you invest so heavily in equipment from a company you’re notably negative on? the competition must be bad? Either way, to each their own).
In the meantime you can state whatever, as you say, “nonsense” you want while I will state my observations from my own experience (watched comp. tests including heat, pre-buying. I knew what I was getting into. Not getting “hot” was the tests finding, not getting hot in my own use is still the finding). Again, you can say and not say whatever you want with your own knee deep M1 equipment experience. Thank you, I’ll do the same.
Again, My MBA M1 does not get “very hot”. I’m clear on what you says yours does and you’re now clear on what mine does. Yes, It has a very localized place/specific area that I can feel warmth to the touch when it’s under extreme resource usage, “vert hot” it is absolutely not.
And While I don’t have “several” of them, I do have an HP(my old laptop):, a 2020 Lenovo (my newest) and a Dell(my company issued laptop 2+ years old). I work with dbs and VMs, I’m well aware on taxing HW resources and what a laptop feels like to be described as actually very hot. Personally (as I’ve said before here) I like my Lenovo but the fan kicks in easily and it can actually get hot (the HP was a giant workhorse but has one foot in the grave - that beast got white hot. On the Dell, I wish my company would allow me to use my Lenovo so I can give the Dell a more wanted home. For its form factor and what it does, the thermals are a negative among all). My MBA M1 is cooler, quieter, much more often quicker, most of the onboard exp. is better (not the camera, IME) and the vast majority of times is the outright better laptop to use — one that was singularly smoother and easier to integrate into my relatively-ish recent plunge into the eco. And it’s pricing is absolutely competitive for the two I bought (noting I got my MBA from Apple refurb store for 850).
My M1 MBA and M1 iMac both get to over 90C when pushed hard for 30+ minutes. This only happens once in a while, but they both absolutely can get hot, depending on your workload.
