The zEC12 microprocessor (zEnterprise EC12 or just z12) is a chip made by IBM for their zEnterprise EC12 and zEnterprise BC12 mainframe computers, announced on August 28, 2012. It is manufactured at the East Fishkill, New York fabrication plant (previously owned by IBM but production will continue for ten years by new owner GlobalFoundries). The processor began shipping in the fall of 2012. IBM stated that it was the world's fastest microprocessor and is about 25% faster than its predecessor the z196.
