Editing pezy/pezy-scx/pezy-sc4 (section)

== Overview ==
The SC4 will be introduced by [[PEZY]] along with their fourth-generation [[ZettaScaler]]-4.0 supercomputer series. The SC4 is set to incorporate 16,384 cores along with 8-way [[simultaneous multithreading|SMT]] support for a total of 131,072 threads, twice as many cores as {{\\|PEZY-SC3|its predecessor}}.

Operating at 1.6 GHz, the PEZY-SC4 will have a peak performance of 105 TFLOPS (single-precision) and 52.5 TFLOPS (double-precision) while consuming around 640 Watts. The PEZY-SC4 is expected to be manufactured on [[TSMC]]'s [[5 nm process]].
