It became the fastest supercomputer in the world in the June 2020 TOP500 list[6] as well as becoming the first ARM architecture-based computer to achieve this.[7] At this time it also achieved 1.42 exaFLOPS using the mixed fp16/fp64 precision HPL-AI benchmark. It started regular operations in 2021.[8]
Fugaku was superseded as the fastest supercomputer in the world by Frontier in May 2022.[9]
