Circa 18-24 months ago - everyone was waxing lyrical about the M1 Macbook Air.
I'm still in awe just how capable it is.

Anyone able to give a list of what apps are single core vs multi core.

On single core - the little M1 Air still holds it own.

But I can't work out what apps use multicore. Can anyone help?

Most applications are single core, there's a few which are multicore.
 
I hope everyone who buys this new Mac studio also buys UPS or some sort of backup power supply.
or exercise regular backups. Unless you don’t care about data integrity.

Also this:
Even with underground supplied electricity, I've had UPS's in the house for years.

A 1500VA unit for my two-post rack of IT gear and a couple of others in my home/office and in the family room to cover the TV and other electronics.

They keep things humming along during infrequent brown-outs more than for (extremely rare) outages of any duration. Also protect against lightning strikes which have wasted all sorts of things in a couple of my neighbor's places in the past.

I've done backups for many years as well. Haven't needed to restore very often but definitely happened sometimes. With the newer Mac's the odds of recovering data from dying or dead storage are far more difficult if not impossible.

How about comparison of MBP M1 Max vs Mac Studio M1 Max? while they should be even at the line, what about heat/fans/throlling?/etc —comparisons

there are a couple good ones on YT already. See ZoneOfTech.

no surprises, core-for-core they are basically the same. Studio runs cooler, MBP faster at some disk stuff due to the SSD on the board. Just get the one that suits your needs.

Some are saying the Studio should be faster due to case design and PS ("click-me!" Max Tech of late) but I contend the SoC is the SoC, and all the extras on the Studio are there for ahem, modular expansion on the ports.
 
LOL. Plenty of people need more than 64Gb, some even 128Gb memory, not so much the amount of power it comes with.
For what? Storing that much in memory suggests your CPU is doing something with it. Otherwise it might as well go to disk. My workhorse machine has 16. My various data crunching servers have had 64-256, but they were maxing out the CPU too.

It's not just single vs multi. Regular M1 has 4 high-performance cores. Question is, which things can take advantage of more than 4 cores. (Or 10 in the Max vs Ultra comparison.)

Some programs can spin up any number of workers, but memory sharing limits how many cores they can really benefit from, and this will depend on factors besides the CPU. SDN I was working on at a research lab specifically did best with 13 CPU cores on the 32-core test machine, with diminishing returns up to that point. And some programs only use a fixed number of cores, like Google Meet using 2 for the heavy stuff afaik.

I do not believe you. Sorry

Had a 2 hr zoom meeting with my core i7 MBP yesterday on the desk on battery most of the way. Fans were quite loud by the end. For a zoom meeting. With no other programs running.

Intel MBPs get hot.

Which is why I love my M1 Pro 16”. It’s a paradigm shift of what a laptop can be.
Something is wrong. Do you have a dedicated GPU? Cause I'd blame that before blaming the Intel CPU.
My 2015 13" MBP (which is of course Intel) never gets hot just running a Zoom meeting. Zoom is pretty efficient compared to the other video chat apps; only FaceTime is lighter.

Agree that "All Intel MBP's" do not run hot. (Edit) Some of the later 16" Intel models appear to have far more problems of this nature than others according to herds of folks on reddit.

I run Teams primarily and sometimes AdobeConnect and Zoom with no problems. I've owned the following MacBook Pro's in the past decade or so and none of them ran hot for any length of time:

2010 15"
2012 15" (custom build w/ Matte display)
2015 15"
2020 13" 10th gen i5

Also had a 2020 i7 Air for a few weeks before deciding to return it for the newly released 2020 10th gen 13" MBP (that had dual fans and far better I/O performance). Wife still uses m3 2015 12" and I had a 2017 i7 12" for a couple of years as well.

Avg CPU temps on my 13" MBP that has been running (Catalina) for the past ~3 hours are 26.4C with ARD, Chrome, Firefox, iTerm, LR Classic, PhotoSync, Terminal, Turbotax, Word 2016 and other background OS processes running.

Still in the process of shifting more duties to the Studio Max (before I deal 13" to my wife). Low RPM fan running all the time is fine by me.

Thanks for the video. Anyone know where I can get the under the desk mount for the 16" MacBook Pro (see video around 06:50)?

Thanks!

Seems there were two releases of 16" Intel MBPs. First one in late 2019 had only integrated graphics, second in early 2020 had dedicated. So if all these complaints are from users who have dGPUs, I'd not be surprised.

(The one with dedicated also has integrated, but the automatic switching tends to prefer the dedicated.)

Spot on. I basically didn't like my 2018 MBP 13 i7. Lovely format, but frequently ran warm, with fans blasting. My 2021 MBP 14 Max is a dream. Runs cool and (honestly) I am yet to hear the fan. Love the machine.

Even if you are using single-threaded apps, having more cores means that working with multiple apps is smoother.

Only if you have multiple apps each using 100% on the single thread even when you're not interacting with it. That's not common. I can see Zoom in background + something else in foreground, but that's 300% CPU at most. Can't remember the last time my machine has been CPU-constrained.

So yeah, I consider multi-core performance important for typical users... only if you limit to 3 or 4 cores. Would certainly not want a regular M1 if it were single core.

Filmmakers and commercial promo producers/editors & VFX artists are probably the no. 1 group of people who these machines will be a God send. Save 10 minutes on a 20 minute timeline can mean saving 45 mins on a 30 track timeline… or color correction layers. Video it’s complicated the more you want to hone it in for a desired emotion.

I’m not saying YouTubers and the modern editor couldn’t benefit from these machines - the ability to roll in real-time without loosing frames is EXTREMELY impressive.

These machines give back creative power to the video artist while minimizing the stress of deadlines and computer issues. I can’t tell you how many times FCP, Premiere, and After Effects misbehave because of lack of resources on larger projects.

I understand the average media guru won’t feel the help, but a powerhouse editor working for a production craving company will benefit instantly for it.

The fact is any editor will benefit from a leap to m1 from intel. The memory being that accessible to the chipset has already enhanced my every day workflow. I can open a gig photoshop file and still be super creative, push its limits, and get it to print without huge crashes.

Now I’d love to hear from someone who is mastering 250 channels of audio and feel the responsiveness for that.

To me the move to this architecture makes computing stable, multitasking easy, and everyday tasks blazing fast. The pro, max and ultra chips seems to bring back the joy of telling a story to complex editors and producers who want to creatively push the boundaries.
Yeah, people don’t get that it’s not so much saving 10 minutes as it is you know you can achieve more in the same time. You can say “I can apply those effects, I can turn the detail level up, I can use more advanced filters” and still get your work completed on time.

It’s an old non-retina i7 with discrete graphics. It slowly heated up and by the end of a 2 hrs the fans were distracting.

My only point was the poster claimed he has never had a mac laptop get hot. I gave a recent example of even a basic service causing thermal runaway over time.

This simply does not happen in the M1 Pro 16”. I watched reviews showing it can happen on the Max and even Pro sandwiched into a 14”, which is one reason I went with the 16”.

I have seen reviews that show if you really push your setup for extended lengths there is a slow thermal runaway that will get the fans up. Not hair dryer, but up. Most people can’t push it that hard because you need to peg the cpus and gpus which is hard to achieve in real life.

Idk about you, but I always fuzzmark my GPU while I'm watching two multithreaded chess AIs compete.

I am surprised. Do you use zoom as audio only? I have GPU acceleration turned off in both zoom and teams but still my Mac could take off anytime with that fan speed. 2019 16” Mac.

It’s less when I don’t use an external 4K monitor but still a lot of heat and drains the battery. There are many with the same configuration in the office who complain that their battery lasts for less than 2 hours with zoom on.
I am running a 2016 macbook pro 13 inch with touchbar with i5 (with no GPU of course) and I haven't noticed any fan spinning while using zoom. However zoom does kills my battery in about 2 hours or so..

Yep. We got to about 1:40 and I had to plug in. Which shows how much power it uses.

We had to be on Catalina because it’s a non-retina MBP, but the zoom was fresh as it was updated before the meeting.

I render out of ArchiCAD which pegs all CPU cores at 100% for the duration, but I don’t know if it also taps GPU cores. I think the GPU is used during 3D perspective model view while I work.

But just starting the render would turn my old MBP fans to ludicrous speed while i have to put my ear to the computer to hear the M1 Pro fans even after 30 minutes of outputs.

Edit: I didn’t want to risk it since the 16” was only a few hundred more than the 14” and nearly the same size (and lighter) than my 15.6” MBP.
