There are also processors produced from Russian firms:

Looks like all Russian CPUs are SPARC or MIPS-based. I think they're
avoiding Intel-like stuff on purpose, they probably want to avoid any
copyright infringment claim and also having to get a licence to be able to
produce their own processors.

Two years ago I read Russian CPUs are about as powerful and efficient as
five-years old Intel CPUs. I don't know how Chinese CPUs compare, but keep
in mind the world's most powerful computer, the Chinese Sunway TaihuLight, is
running on native CPUs, the SW26010:

The same supercomputer is rated #4 worldwide as far as power-efficiency is
concerned.

To non-Chinese it is, sure! ;-)
