POWER8 is a family of superscalar multi-core microprocessors based on the Power ISA, announced in August 2013 at the Hot Chips conference. The designs are available for licensing under the OpenPOWER Foundation, which is the first time for such availability of IBM's highest-end processors.[1][2]

Systems based on POWER8 became available from IBM in June 2014.[3] Systems and POWER8 processor designs made by other OpenPOWER members were available in early 2015.
