Low power RISC cores (both ARM and RISC-V) are typically in-order actually!

But any core I can think of as 'high-performance' is OOO.

MIPS as well as Alpha AFAIR. And technically itanium, otoh It seems to me a bit like a niche for any performance advantages...

I would not call neither MIPS, Alpha nor Itanium "high-performance" in 2025...

Alpha was out of order starting with EV7, but most importantly the entire architecture was designed with eye for both pipeline hazards and out of order execution, unlike VAX that it replaced which made it pretty much impossible

Alpha 21264 is out-of-order.
