I wouldn't say "super computer" chip (or at least "supercomputer")... I've read the definition of a supercomputer as "some computer that takes specific domain, compute-bound problems and turns them into IO bound problems." (Implicitly, in that statement is the second statement of "and they have a ton of IO too). They're not really general purpose computers, and likely you'd be able to use risc-v or anything else, with specialized hardware, as the basis of a "supercomputer". The power platform, on the other-hand (I'll create a new word here) is a foundation for a "SuperEnterprise(tm)" computer. Power has insane / awesome things like "oh, you can use the ECC bits for ECC and hardware memory tagging[1]." Eventually such things may trickle down to things like ARM or RISC-V, but they're pioneered at the top of the enterprise mountain and trickle down...
