Overview

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.

Products

Poplar SDK
Poplar is Graphcore's software stack with compilers, libraries and framework integrations for PyTorch and TensorFlow. It maps model graphs onto the IPU's distributed memory and compute.
graphcore.ai
IPU-POD
IPU-POD systems combine many IPUs with host servers and high-speed fabric into rack-scale training clusters. They let customers scale from a single machine to large installations with the same software.
graphcore.ai
Bow IPU
The Bow IPU was the first processor to ship with wafer-on-wafer three-dimensional stacking. The added power delivery die raises clock speed and performance over the previous generation.
graphcore.ai
Intelligence Processing Unit
The IPU is Graphcore's processor designed from scratch for machine learning, with over a thousand independent cores and large on-chip memory. Its architecture targets models with irregular or sparse computation patterns.
