POWER9 is a family of superscalar, multithreading, multi-core microprocessors produced by IBM, based on the Power ISA. It was announced in August 2016.^[2] The POWER9-based processors are being manufactured using a 14 nm FinFET process,^[3] in 12- and 24-core versions, for scale out and scale up applications,^[3] and possibly other variations, since the POWER9 architecture is open for licensing and modification by the OpenPOWER Foundation members.^[5]

Summit, the seventh fastest supercomputer in the world (based on the Top500 list as of November 2023^[6]), is based on POWER9, while also using Nvidia Tesla GPUs as accelerators.^[7]
