Template:mpu PEZY-SC4 (PEZY Super Computer 4) is fifth generation many-core microprocessor planned by PEZY. The SC4 incorporates 16,192 cores, twice times as many cores as its predecessor.

Planned to be fabricated on TSMC's 5 nm process, PEZY-SC5 operates at 1.6 GHz and consume around 640 W while delivering performance in the order of 210 TFLOPS (HP), 105 TFLOPS (SP), and 52.5 TFLOPS (DP).

In addition to main memory bandwidth, the PEZY-SC4 supports Wide-IO with a width of 4,096 bit, twice of the SC3. As with the SC3, the SC4 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 2.8 TiB/s per interface for a total aggregated bandwidth of 22.35 TB/s - twice the bandwidth of its predecessor.
