PyPy is a little bit of a pathological case of their benchmark suite requires that much DRAM though

SolidRun has a MiniITX board supporting up to 2x32GB for around $1000 [0]. They also have a preproduction units for another board for $550 supporting as much RAM [1].

They probably had their reasons, but I'm just showing what's available.



Why does the benchmark suite need so much RAM ?

I would expect benchmarks to match typical usage, if PyPy can't run in a couple of GB then choose a better language.

Compiling pypy is memory intensive, I don't believe it can be done in 2GB which is where most of the really affordable ARM devices seem to cap out.

But why do you have to compile PyPy on the same machine you’re testing it on?

Well cross-compiling (aka "cross translation) is made complicated because PyPy doesn't use a normal toolchain, but that's not the problem here. The PyPy benchmark suite itself takes that much memory to run.

You can build OpenJDK with the Hotspot JIT on a 2GB ARM64 system.
