I've just received the M2 MBA with 24gb RAM. It is a night and day difference from my previous M1 MBA with 8gb RAM.
Everything is instant, the previous M1 Mac was constantly showing the beachball.

So definitely, if you multitask a lot, go for at least 16GB of RAM.
Currently it says I'm using 17GB of RAM, App and Wired memory is lower, around 14GB. Not sure if 16GB would have been enough.
same here, except i had 16gb m1 mba lol, once the swaps starts pushing 7-8gb, i got beach ball in places i didn't know i could get beach ball, the recent folder just stopped working entirely, and apps slows down to a crawl when retrieving from ssd instead of ram.

BTW, this my wife's 8 GB 2017 MacBook Air Broadwell Core i5-5350U, running Monterey 12.6.1:

8GB-multitasking.png


The thing that happens is there is significant compressed memory, and only later does the swap come into play more significantly. Subjectively, it feels quite responsive, even despite its ancient Broadwell CPU. Granted, I only had a about half a dozen browser tabs open, and the files in the iWork apps were fairly small, but nonetheless it does illustrate that 8 GB can be quite capable for lighter usage. However, if someone were running all these apps all the time, and with more tabs and larger documents, I'd recommend 16 GB.

When I multitask more significantly on my 8 GB 2014 Mac mini Haswell Core i5-4278U, I might hit about 1-2 GB swap and that's when I start feeling a bit of lag, but part of that is because my CPU isn't fast to begin with. As I said earlier in this thread, 16 GB will be fine for my next work machine with this type of multitasking. However, I may get 24 GB anyway, since this may eventually replace my 24 GB 2017 iMac 27" Kaby Lake Core i5-7600 when it loses macOS support. On the iMac, with even heavier usage, I will usually have no swap, and not much compressed memory.

Thank you for this explainer. Would you please talk more about compressed memory? What's the high end of the 'not much compressed memory' range? Is it an absolute amount? a proportion? Thanks!

This is just my own experience with my type of usage, but my 24 GB iMac usually ever only gets into the few hundred MB range for compressed memory, and swap is usually zero, although for some reason I occasionally may have up to a few hundred MB of that too.

Right now I only have my browsers open, Messages, and Excel with a simple spreadsheet. It says 8 GB is being used, with a further 13 GB of cached applications. That leaves another 3 GB completely unused. Despite this, for some reason I still have 7.5 MB of compressed memory. No swap.

That reminds me. One benefit of having all this extra RAM unused is that it caches previously used applications. If you launch them again, they don't have to reload, as they are already in memory.

Wow, that's impressive. 12 GB of Excel stuff alone. The only time I've ever come close was something like 8 GB in PowerPoint (plus more with Keynote at the same time), but that's also because I believe my version of PowerPoint had a memory leak. Also, it's impressive you have 0 swap and 11 GB of compressed memory.

Anyways, your workflow is a great example of why you do NOT have to be a multimedia content creator to make use of so much RAM.

Yep, between Excel and sometime Tableau you can get pretty crazy RAM requirements.

About the no Sawp, maybe it was because I almost only used Excel all day, and rarely switched to other apps.
 
I cancelled my m2 air order ( still questioning my decision as I like the looks of the air more) and picked up a pro 14, I would definately say 16gb minimum, I was doing web browsing for about 2 hrs last night with up to 8 tabs open in safari- downloading some apps - email - after downloading stopped I fired up youtube and activity monitor- it showed 10.25gb actively being used...I have no plans for hardcore work usage for this machine but the few minimal tasks I have done I wouldnt even look at 8gb ram

Remember though, if you have tons of memory, macOS will use it, uncompressed. If you had only 8 GB RAM, it doesn't mean that extra 2-3 GB would have spilled over into swap. It means you'd just have more compressed RAM.

Compressed RAM is OK, as for mainstream usage it doesn't really affect perceivable performance IMO. The perceivable performance hit comes when you start hitting the swap file on a regular basis.

8 tabs in Safari + email + YouTube is easy for 8 GB. I do that all the time on 8 GB machines, and the responsiveness is maintained, even on old Intel machines. 16 GB is for sure recommended for more heavy multitasking, but what you describe is not a problem, because of Apple's ability to efficiently use compressed RAM.

BTW, given that you say the MBA looks better, I'm curious why you went with the 14" MacBook Pro. For what you describe for your needs, the 14" MBP sounds like complete overkill. An M2 MBA would have been great performance-wise, and the 16 GB would have futureproofed it for many years to come. Did you want more ports or something? That said, the 14" MBP is a very nice machine, and there's nothing wrong with wanting the best. :)

Yes, 32GB would be ideal, but the MBP is too big for me, I need it light and portable. I am one of those that wishes for a 12" MPB.

I use my M1 Air for "general use computing" but I am a bit of a power user. I also use Windows 11 in VM for Windows specific software and lots of ram is needed, but not all the time, so I could soldier on with only 16GB.

I am tempted by a M2 24GB, but at the same time I would wait for a M3 32GB Air or a rumoured 12" MBP....

it was a tough choice but best buy had them side by side and the pro m1 14 16/512 price was the same as a spec'd up m2 air ...better display and slightly bigger, slightly better speaker setup - better ssd performance ... frankly only in certain situations I could tell that one display is better than the other, however I am only now seeing if my eyes conform to the faster refresh rate and they are, looking at my old laptop I can see the lag when scrolling
 
Photos does not play nice with large library exports:

PhotosMemory2.png


I have a little under 60000 photos and videos, and that's what happened when I tried to export the original (unmodified) files all at once. It got to >100 GB memory usage (including >70 GB swap) before it finally crashed. If I export about 10000 at a time it's fine though, and without very much memory usage. This is on my 24 GB 2017 iMac Core i5.

This is probably a memory leak or something though I'm guessing, not an actual need... because it would be absolutely ridiculous for a consumer app to need 100+ GB memory in 2022.

Memory pressure still not in the red though, must be fine ;)
 
I wonder if Apple will introduce a 12GB option in coming revisions, I think it would be nice at this point to have a stock Air model offering more than 8GB, but it's difficult to see them putting 16GB in even the $1,499 model. Maybe the M3 could offer 12 & 24 only with the M2 staying in the lineup to replace the M1 and trimmed to 8 & 16 options.

$1,099 - M2, 8GB, 256GB
$1,299 - M3, 12GB, 256GB
$1,499 - M3, 12GB, 512GB

holy, i thought my 9gb swap on the mba was bad, you take the cake lol

Was the MacBook Air *slow* when it was swapping?
random things start to act up, my recent folder refuse to load and its just a blank, team would refuse to connect to camera, word would not save properly, basically making workflow more frustrating.

In the near term, IMO it's very unlikely. There is simply no need for 12 GB at the low end, even for M3, so I don't see Apple spending extra money to do this. For the low end, 8 GB will be sufficient even until 2024 IMO.

While I think a 12 GB entry level would be awesome, from a business and profit perspective Apple would probably be much better off keeping 8 GB for a couple more years, and making people pay for 16 GB if they need it. Another idea would be a 12 GB option for $100 more than 8 GB, but I don't see Apple doing this either, even though I think a lot of people would do that upgrade.

On a personal note, I still haven't completely decided what I'm going to do with my (likely) M2 Mac mini purchase come spring. I will need than 8 GB. 16 GB would probably be sufficient the vast majority of the time, but at $200 more (or in my case CA$225 / US$170 more for edu), I probably will just get 24 GB, just because. I already have 24 GB in my iMac, and the M2 Mac mini will probably eventually replace the iMac.

BTW, are 6 GB chips common? Just wondering. A 12 GB machine would likely be 6+6 GB chips. Right now the configurations are 4+4, 8+8, and 12+12. This provides a nice 3 tier system separated by 8 GB at each tier transition.

P.S. When I bought my 2017 MacBook, 8 GB was fine most of the time for me, but occasionally a little restrictive, as I sometimes would need to do heavy business application multitasking on the road. Had 12 GB been an option for me, I would have gotten that, especially since my plan was to keep it more than 5 years, and my memory usage on average has gone up over time. However, 12 GB wasn't an option, so I paid the extra Apple tax and went all the way to 16 GB. The ironic part is my work has since changed and I essentially never need to do the heavy lifting on my laptop anymore, as I now always just use my 24 GB iMac for that. These days I just have entry level needs for my laptop, so after 5 years, my laptop memory usage is less than what I needed back in 2017, despite the fact I was running macOS 10.12 Sierra back then and now I'm running macOS 13 Ventura.

Yeah, people keep saying swap is fine on these machines because the storage is so fast, but when things get complex, weird things happen. Haven't some swap is indeed fine, but consistently having high swap is a recipe for disaster IMO. Not only do some things slow right down, lots of YouTubers report that things become unpredictable in their workflows when they hit the swap a lot. They'd get weird glitches and random crashes on 8 GB M1 machines. Those problems disappeared when they upgraded to 16 GB M1 models.

I'm not saying 8 GB is bad by any means, and I still stand by my statement that 8 GB is enough for entry level (which is most MacBook Air customers), but not everyone is entry level of course.

and the thing is, even if you are entry level, as soon as you load up 7-8 tabs with emails, and couple other electron apps, you're already seeing 6-8gb of ram usage.

Well, 6-8 GB of RAM usage is not really a big deal, since Apple happily compresses memory before having to resort to significant swap usage. Also, some of that is sometimes cached applications, which can be purged if necessary.

Agreed it's not happening unless they can make money from it, but as they charge $200 for 8 to 16 it might be a way of squeezing an extra $100 per sale at the more price sensitive end of the market, sort of like how the 128GB iPhones were a $50 upgrade from 64GB for the XS to the 12. (e.g. above scenario where they can increase the base M3 price by $100 over the M2). The other part is having an >8GB stock option, though I guess they would more likely point to the 14/16 inch MBP as an upsell than a 12GB MBA.

I usually say 8GB is still ok unless you know you need more, but I'm less certain of that lately. Especially for people who want to keep a computer for years to come. With the (hopefully) upcoming MBA 15" I'd like to replace my 2015 15" with it would be a case of halving RAM going forward while apps are only using more than they did 7 years ago, or having to BTO a machine and lose the option of offers from other retailers which frequently take £100s off Apple's prices, and JL for example offer a two year guarantee as standard. It would probably be less of an issue but Apple's prices have skyrocketed here over the last year! With this machine I've never really had to think about RAM usage as 16 is plenty for me, but I'd hate for it to become something I do have to think about.

Idk what RAM skus are common, but they've got 6GB ones for the iPhones. It doesn't look like they currently use the same RAM chips between the iPhone and MacBooks (LPDDR4X vs LPDDR5) but I guess that could be an option to help economy of scale?

I have never heard of a 6gb ram chip. They come in sizes like 2gb, 4gb, 8gb, 16gb, 32gb, and so on.

So for a 12gb configuration the likely combination is an 8gb module and a 4gb module.

They still run in dual channel mode regardless if the chips match. In older cpu and motherboard configuration you would have to run two of the same chips to get dual channel like 4+4 to get 8gb dual channel or 8+8 to get dual channel but now you can get 8+4 to get 12gb dual channel or 16 + 8 to get 24gb dual channel.

So there is no need for two 6gb chips to get 12gb. Apple could use 8 + 4 which a lot of PC OEM's already do in low mid range laptops.

All new cpus support non standard ram combinations to give dual channel ram.
