Post-K is the planned successor to the {{\\|K|K Computer}}. Unlike {{\\|K}} which is based on [[SPARC64]], Post-K is an [[ARM]]-based supercomputer designed based on {{fujitsu|Post-K|a custom microprocessor|l=arch}} that implements {{arm|ARMv8|ARMv8-A}} with 512-bit SVE vector support. Post-K targets around 100x the application performance of {{\\|K}} and is expected to have a power consumption of around 30-40 MW.
