Depends on the workload and the # of cores in the POWER9 chip(s). The Socionext has 24 cores! Edit: Admittedly only massively parallel workloads will be faster

Depends on the workload and the # of cores in the POWER9 chip(s). The Socionext has 24 cores! Edit: Admittedly only massively parallel workloads will be faster than the POWER9, and only if the POWER9 has limited cores. A bit of a stretch for most use cases.
