No this is NOT "Zettascale supercomputer", not even close, that metric counts FP64 only, this thing according to your article targets 600EF in FP8 Sparse. Can't believe this needs to be pointed out on a tech website
RIKEN, Fujitsu and Nvidia are joining forces on FugakuNEXT, Japan's next flagship supercomputer. Targeting 600 EFLOPS FP8 and a hundred-fold performance boost over Fugaku, the system combines new Fujitsu CPUs and Nvidia GPU accelerators to power AI-driven science by 2030.
