I can't imagine the utility bill to run this monster!

Fugaku is powered by ARM A64FX chips, of which it has 7,630,848 cores. When tested against the HPL supercomputing benchmark, it set a world record of 442 petaflops, and against the high-performance computing artificial intelligence workload (HPC-AI) benchmark it maxed out at 2.0 exaflops, beating the previous record (also held by Fugaku) of 1.4 exaflops set in June 2020. According to Top 500, Fugaku's HPC-AI benchmark was "the first benchmark measurements above one exaflop for any precision on any type of hardware."
