Template:mpu PEZY-SC3 (PEZY Super Computer 3) is fourth generation many-core microprocessor planned by PEZY. The SC3 incorporates 8,096 cores, four times as many cores as its predecessor.
Planned to be fabricated on TSMC's 7 nm process, PEZY-SC3 operates at 1.33 GHz and consume around 400 W while delivering performance in the order of 87.2 TFLOPS (HP), 43.6 TFLOPS (SP), and 21.8 TFLOPS (DP).
