    X86 is not suitable for the market that Power9 super computers make up. Requirement open hardware inspect-able silicon design is a requirement of that sub set of the super computer market. Currently this is a fight between Sparc based and Power 9 based cpus with risc-v based in future. This is roughly 4 percent of the super computer market that has this requirement. So 96-97 percent of the market where x86 is in super computer is basically totally saturated.

      Indeed Fujitsu has done just that. The post-K computer being built in Japan by Fujitsu is an ARMv8.2-A architecture with variable length SIMD instrucitons (SVE, Scalable Vector Extensions) that they specifically designed for HPC. See http://www.fujitsu.com/global/about/...8/0822-02.html for the A64FX chip.
