Genuinely curious, what is an example of a beefy ARM machine?

Anything with a ThunderX processor is maximum beefy. You can get on-demand servers like that from places like Packet. AWS also has their own A1 instances with lower core counts. These would all be good for cross compiling/builds.

Comedy answer: iPad Pro

I mean, the iPad Pro does have a relatively beefy processor. If only you could run arbitrary code on it.

A lot of instruction sets aren't there yet, but https://ish.app is doing a truly incredible job in this regard.

Gives you a working Alpine Linux installation which you can download and install packages for normally, all within the bounds of the normal Apple sandbox, with decent enough performance.

It doesn't have SSE or MMX yet, so eg Go and Node aren't usable at this point. But a shocking amount actually does work perfectly, so it's only a matter of time as more instruction sets are implemented.

It's pretty atrocious that you have to run an x86 emulator to use your iPad "pro" for this stuff. This project is super cool though.

Actually wouldn't a userspace ARM "emulator" be faster than an x86 one on an ARM device? Or are you so far removed from running actual CPU instructions that it doesn't matter?

I suggest you also check out UTM (Universal Turing Machine), an emulator for the iPad that you can build and that allows you to emulate many different architectures and tun OSes written for them (including ARM).

Actually looks like MMX was just released, so Go is now running. It can't build yet though.

Amazon Graviton2 instances are faster (and cheaper) than x86_64 machines in the same class.
