IBM presented its ultra-low power AI processor at its Zurich technology meeting today. Called Hermes, the core is a scientific demonstrator made on 14nm CMOS that has scored a record energy efficiency of 10.5Top/s/W, plus a density of 1.59Top/s/mm2. The technology is mixed analogue and digital compute-in-memory, using multi-level phase-change memory – the latter added to ...
