On: Amid chip shortages, companies bet on RISC-V

Indeed, but conversely, China will have access to ARM no matter what. This also means that we can sanction all we want, they locally have the fabs and IP to create ARM, RISC-V, MIPS and even x86 CPUs (and they are already doing all of that). Granted, their fabs can't do top-of-the-line lithography (yet?) but since they have already created 64-core ARM server CPUs and some custom AI silicon they can get horizontally scaled performance regardless. This is of course their focus: make sure they can make computers and related equipment domestically no matter what.

They do have access to ARM, sure. But they also have access to RISC-V, which is technically superior and free of the troubles associated with ARM.

What is superior about RISC V technically?

Code density is a good one.

L1$ is always starved, thus it is always good to fit more code in it.

China wants to sell chips and gadgets with chips inside. Legally questionable access to ARM will not help with that. RISC-V solves the problem.
