Graphcore is a British semiconductor company founded in Bristol in 2016 that designs the Intelligence Processing Unit, a processor architected specifically for machine learning rather than adapted from graphics. Its chips place large amounts of memory directly on the die and expose fine-grained parallelism, an approach aimed at sparse and irregular models that map poorly onto conventional accelerators. The company sells IPU systems and the Poplar software stack to research and enterprise customers, and has operated as a wholly owned subsidiary of SoftBank Group since its acquisition in 2024.
