PEZY Computing is a Japanese fabless computer chip design company specialising in the design of manycore processors for supercomputers.

PEZY Computing was founded in 2010 and is headquartered in Tokyo, Japan.¹ The name "PEZY" is an acronym derived from the Greek metric prefixs peta-, exa-, zetta-, and yotta-.²

The company develops manycore processors for high-performance computing. Its first processor, the PEZY-1, was introduced in 2012, followed by the PEZY-SC, launched 2014.³

In 2015, computers using PEZY processors occupied the top three positions on the Green 500 supercomputer list. One of the most efficient being RIKEN's Shoubu computer with 7.03 GFLOPS/Watt.⁴⁵

The company has collaborated with other technology firms, including a 2016 partnership with Imagination Technologies to integrate MIPS-based CPUs with PEZY's manycore processors for high performance computing applications.⁶

In early 2017, the PEZY-SC2 chip was launched.³ In November 2017 the Gyoukou supercomputer was unveiled, incorporating PEZY-SC2 chips.⁷

In December 2017, president Motoaki Saito, and employee, Daisuke Suzuki, were arrested on fraud charges related to inflated expense claims submitted to Japan's New Energy and Industrial Technology Development Organization (NEDO).⁸³⁹ Subsequent investigations identified additional improperly obtained subsidies, and in 2018 Suzuki received a suspended prison sentence for his involvement.⁹¹⁰
