Overview[edit]

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 SMT support for a total of 131,072 threads, twice as many cores as 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.

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.
