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 ninth fastest supercomputer in the world (based on the Top500 list as of June 2024[6]), is based on POWER9, while also using Nvidia Tesla GPUs as accelerators.[7]

The Summit and Sierra machines based on the AC922 are getting 22 core versions of the chips ... IBM could later, as Power9 yields improve, add a 24 core option.
