ARM CPUs please

Fundamentally, an ARM laptop should run cooler than its Intel counterparts. This could mean that ARM laptops need to be throttled less, allowing them to run faster and do more work.


There’s been more than one thread talking about this. The modular design definitely increases the odds that an ARM swap is possible, but first there needs to be a good ARM chip that isn’t an M1. The only real game in town right now is the Snapdragon SQ2 which is not that impressive.


Really? I don’t know enough about what is available (right now) but I do feel that aarch64 seems to be the (or at least a) route to explore with the philosophy! There are some obvious advantages to this architecture


There are some disadvantages to the ARM architecture as well. For example right now each SoC has to be targeted specifically by OS developers for support. This is a huge overhead and ARM boards can “die” essentially from lack of software support. For a company like Framework that is targeting sustainability the move to ARM is going to be more complicated than it was for Apple which is both making the hardware and supporting the software.


… sure. That is true about ANY architecture. A simple solution could be to to collaborate with the Raspberry Foundation! A modified board as is in the 400 with better cooling and more RAM, clocked to, say 2.2GHz?


It’s specifically not true about the x86 architecture. It is much easier for OS developers to add support for new x86 motherboards vs new ARM SoCs.

I like your suggestion about partnering with a proven manufacturer in this space like Raspberry. That seems to me like it would be the easiest way to support ARM. You wouldn’t even need to partner all that closely someone could make a compute module IO board that fits the Framework form factor. However for that better software support you have to sacrifice performance because the Raspberry Pi Computer Module 4 SoC still doesn’t even compete with the low end x86 processors.

If your goal is to create a sustainable laptop without sacrificing performance this year then ARM just isn’t there yet. I personally hope that it gets there and Framework has mentioned that it is something they are looking at for the future. But I’m glad that they started where they did since if this laptop takes off as a platform then when it does make sense to transition I won’t have to buy an entirely new laptop.


… yes, that’s a tall order!

But the price starting at $999 could be significantly lowered … an entry level laptop in South Africa at the moment is less that half that price! If an ARM based framework laptop could compete at that level (with sacrificing a bit of performance) the buyer could be tempted to buy the Intel-mainboard later the AMD-mainboard (for gaming maybe?) and use them all in the same framework enclosure when needed!

Also, if the price of Win10(or 11) bloatware could be removed …, maybe partnering with a linux distro of their choice - imagine the possibilities !!


Well there’s already great news on this front. The Framework DIY edition is already $139-$199 less expensive if you don’t get the Windows 10 License and want to run Linux instead. No distros preinstalled yet but they have announced that they are sending laptops to distro maintainers to improve support and that may lead to partnering officially with distros in the future. I personally went for the DIY edition for exactly this reason since I don’t intend on running Windows 10 or 11 on it ever. Windows on ARM support is a whole separate set of issues. When ARM is eventually supported officially by Framework I imagine it will be Linux first.

This part is really the sticking point in our conversation (which I’ve quite enjoyed by the way). I cannot speak for Framework since I am not employed by them but it seems to me they are unwilling to sacrifice performance, it seems as important to the overall design of the laptop as the repair-ability and the Expansion Card system. Which makes a lot of sense, if people want a budget ARM laptop with decent repair-ability and reasonable performance there are already great options out there in the Pinebook Pro. Pine64 is great at providing parts for repairs and even upgrades for some of their products like the PinePhone. It’s not as modular and repairable as the Framework but it comes close enough to illustrate a point. Framework could probably release an ARM board that is equal to the performance of the Pinebook Pro but it would be a very different product to the high performance Framework Laptop for the end user. I think Framework is interested in offering users choice but not if it means altering the design of the product.

If I allow myself to dream of a bright future where lots of people adopt the Framework then this is what I envision as the future of ARM on the platform: First community members release an ARM PCB probably a Raspberry Pi Compute Module 4 based board that Framework owners who are interested can buy on the Marketplace and run in their Framework laptops with no official support from the Framework team. Then hopefully just a few years down the line the ARM ecosystem has changed and Framework can design a mainboard that runs on ARM without sacrificing the overall design of the laptop which they will officially support.


Excellent idea! I’ve also enjoyed your knowledgeable insights …

@Shaun_Kingston and @Rhodesian The Raspberry Pi CM4 is something I had thought of as well, and mentioned here: Raspberry Pi CM4?
@nrp replied that it’s technically possible, and that they’d be open to working with someone on it…

@Dan_Brunsink It seems to me to be the easiest option. The Compute Module 4 has a small vertical footprint now that it isn’t in the DIMM form factor like the old compute modules. So I imagine it would just take an enterprising group to make an IO board that fits the framework form factor. I do foresee some difficulties however. First I’m honestly not sure if the CM4 is capable of supporting the expansion card system and second the thermals might also be a problem as the raspberry pi 4 SoC runs surprisingly hot. But those things might not be deal breakers for people who just want to run ARM in their sustainable laptop case. Maybe a board based on the CM4 would have its own custom expansion cards also created by the community that wouldn’t be based on USB C but some other system to expand the IO of the CM4 based board. Or at least a way to make the IO ports flush with the outside of the laptop.

Are there any plans to introduce ARM CPUs to the framework line up? Would love the opportunity to create a framework laptop with an ARM processor setup

ARM when?


When it’s ready. ARM support is lacking everywhere.

it’s not even the fact that there is just one maker outside of apple (qualcomm) but right now there is just a single model (snapdragon 8cx gen3) of arm chip that one can consider, and that model can’t even compete with apple’s M1 (let alone the later ones).

there are rumors about gen 4 being an insane improvement (let’s assume it is, which we don’t know), but even if framework manages to strike a deal with qualcomm to produce a motherboard to be delivered around gen 4’s launch date, i doubt it’d be before 2024.


I just saw this laptop which has a carrier board innards for a SBC?

I was wondering is the pinout of these Computer-on-Module standardised?

If they are, perhaps we can build some kind of carrier board that can be upgraded or something.


The Raspberry Pi 4 CM uses a pair of high density 100 pin connectors for connection to IO.

This is using a MXM-3 edge connector to connect the CM to IO. This does not appear to be a RPi compatible CM module.

Most interestingly this appears to be using Louis Rossman’s favorite fan placement strategy.

Hi, I just discovered this company and i think it’s great to be able to update/replace parts of the laptop, so my next one will probably be a Framework laptop (with linux).

Quick question; I saw there are for now just x86-64 cpus available. If in the future Framework delivers ARM “packs”, do you think will be enough by replacing just the mainboard? All the other hardware could work with both arm and x86-64 cpus? If that’s possible would be super great.

At least if you replace the mainboard from Intel or AMD to Arm, you need to reinstall OS for Arm (aarch64) system. The binary is different. For example, you can see Fedora Linux has x86_64 and aarch64 iso images.

  • For Intel and AMD x86_64 systems
  • For ARM® aarch64 systems

Below is the result on the computers that I can access.

On Ubuntu 22.04 (jammy) arm64 (aarch64):

$ uname -m

$ file /bin/ls
/bin/ls: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/, BuildID[sha1]=63260a3e6e46db57abf718f6a3562c6eedccf269, for GNU/Linux 3.7.0, stripped

On Fedora 38 x86_64:

$ uname -m

$ file /bin/ls
/bin/ls: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/, BuildID[sha1]=a146002a40b622e4d8420c5b96513f0784c8eb7b, for GNU/Linux 3.2.0, stripped

Sure, you’re right, the OS and all the binaries would have to be changed to their ARM compilation. (Having the user’s personal files stored in a different partition could make the switch less painful) . My question was just about the hardware level. Software obviously would change.
