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).

In addition to main memory bandwidth, the PEZY-SC3 supports Wide-IO with a width of 2,048 bit, twice the twice of the SC2. As with the SC2, the SC3 will use ThruChip Interface (TCI) interfaces in order to communicate with the TCI-DRAM chips. This chip incorporates 8 interfaces, operating at 3 GHz for a bandwidth of 1.525 TB/s per interface for a total aggregated bandwidth of 12.2 TB/s - over 5.8 the bandwidth of its predecessor.
