Also check out Ariel OS (https://ariel-os.org), which is built on top of Embassy.

> Top end CPUs are about 3x faster than the comparable top end models 3 years ago

I wish that were true, but the current Ryzen 9950 is maybe 50% faster than the two generations older 5950, at compilation workloads.

I felt a great disturbance in the Force, as if millions of voices suddenly cried out in terror and were suddenly silenced. I fear something terrible has happened.

Also, the Ryzen 9 3950X. It has a bit more punch than the 3900X, for ~200$ more.

I built one, a Noctua NH-D15 can cool it at 16*4ghz at 700RPM, so basically almost inaudible even at full load.

No ECC, though.

Technical differences aside:

RIOT is the only mentioned OS with a copyleft license (well, LGPLv2.1), trying to create a FOSS alternative in the embedded/IoT space.

With permissive licenses for embedded software, open source usually ends at the factory.

Original author of RIOT here.

Using RIOT you'll get at least multi-threading, power management, a choice of network stacks, a bunch of community-supported libraries and drivers with an extensive test suite, ...

Also, you'd have a clear upgrade path, as applications written for RIOT's API will compile (almost) unchanged for all of RIOT's target hardware. Arduino becomes to slow? Change some pin defines, re-compile for a fast Cortex-M. Intrigued by RISC-V's openness? Recompile for the Hivife1 to find out it's real-world performance with your application.
