M1 with 16 GB of RAM?

Buying Question

I plan on getting an M1 Air this december and I'll be using a Windows VM to use some very light programs (don't worry, they do work with Microsoft's translation layer on Windows on ARM) while using AutoCADon MacOS.

Apparently Windows 11 requires 4 GB of RAM (Even if I install Windows 10, I would be upgrading to Win11 later down the line), which means I would only have 4 GB for MacOS.

My question is, should I spend the extra bucks to upgrade the M1 to 16 GB of RAM when I purchase it?

Yes. I would advise anybody who can reasonably afford the RAM to buy it, even if they’re not running VMs.

This. I would second that. Did the same 16GB / 512. As someone who multi-tasks a lot, it definitely reduced anxiety and improves the overall health of the device. I was seeing a lot of yellow lines in the activity monitor with the base config so ended up exchanging to this.

What is your reasoning? If someone only plans to use their machine for light programs, what would they possibly gain from having 16 > 8?

Headroom, with which comes longevity.

The first problem is that self-identified “light” users may not actually end up being so light. The average user’s ideas of what is demanding has sharp limits. Simply using the web in 2021 can be a severe resource hog depending on the websites. Extra RAM will never hurt.

The second thing is that what’s good today is often not so great tomorrow, even if your use case doesn’t really change. My wife’s computer had a very average 4gb of RAM at the time it was purchased and for her use case it was fine. Fast forward four years alter and 4gb of RAM is a bit of a pinch and her model, like all the modern models, does not have upgradable RAM. Meanwhile, my 10-year-old computer with 8gb of RAM for its entire life is now.. simply entry level spec.. and it’d still be doing billable hours if it wasn’t for other age-related problems.

As I said though, my recommendation is with the qualifier, if you can comfortably afford it. If you’re a light user that is pushing your limit to afford. new $1000 computer, then by all means buy what you can afford. But if an extra $200 isn’t a strain, I recommend investing it.

What if you were stuck between only one upgrade. Would you do the 16gb or the 512 ssd

Then you have to consider the realities of your use case.

For most people, the RAM is going to be more of a benefit but there are definitely cases where only 256gb of on board storage is an issue that isn't solved by external storage.

I'd say RAM should be a priority over syorage as you can always connect external storage devices but there's no such thing as external RAM

I believe Windows would be limited to 4 GB, so the translation layer in Windows wouldn't eat the RAM left for MacOS, but yeah, I was thinking leaving MacOS with only 4 GB wasn't a good idea as it would also increase swap usage

Useful link, thanks!

Which means I'd only have 4 GB left for both MacOS system memory and graphics memory

Well, 16 GB it is. Ty!!

Apparently Windows 11 requires 4 GB of RAM

As a system minimum requirement, that is. It doesnt use anywhere close to that though..

I don't know too much about virtual machines, do you actually have to reserve 4gb for the VM to run windows in it?

Anyhow - i have the least powerful version of the M1 air, and it has surprised me beyond belief thus far. I use it for programming, and i often have a big bulk of ram greedy programs running, and even with my 8gb i haven't had any issues at all.

In fact, it often feels like it's running smoother than my windows desktop, which has 32gb DDR4 @ 3600mhz. It just feels like ARM processors are not as RAM dependant as x86, in my experience.

ddnavaOP•

Yeah, I'm not sure if a VM reserves the 4 GB entirely when it's running, which is my main concern as it would also increase swap usage

Edit: after checking it out, you def want 16 if you plan on running a VM

fyi, autocad on mac sucks assholes, and autodesk isn't planning on doing any future releases on apple silicon platforms

I've been using AutoCAD for Mac since 2014/2015. I know it's not as good as the Windows versions (I use both on a regular basis), but if I have a very lightweight laptop with great battery life and thermals I might as well keep using it

my_cat_sam•

yeah its severely limited in features compared to the windows version, and its pretty much EOL on osx. won't be any more updates to the mac versions from here on out.

yeah i'd love to be able to work off my MBA on the go when needed, but i wouldn't advise anyone to buy a mac if they need to use any autodesk product.

( and i'm not going to pay several hundred bucks to use their latest version on mac running rosetta, and there isn't yet a way to crack it on an m1 as of now )

ddnavaOP•

That's fair and it's a good thing that you warn people about it.

That said, I am well aware of my workflow and the MacOS version has all the tools and features I need, which is why I'm confident I can keep using it

my_cat_sam•

yeah if it works for you then great.

though i am super bummed that they've always neutered it on osx. Its the only thing keeping me from going all into the apple ecosystem.
