Template:mpu PEZY-SCnp (SC - Super Computer; np - New Package) is a revised version of the PEZY-SC model by PEZY introduced in may of 2016. The new model uses a slightly larger package, lower core voltage, slightly higher core frequency, and thus higher performance. The PEZY-SCnp is said to deliver 1.57 TFLOPS (double-precision). PEZY also upgraded the connections from PCIe Gen2 to Gen3. As with the PEZY-SC, the SCnp is also manufactured on TSMC's 28HPC+ (28 nm process).
Architecture
- Main article: PEZY-SC §Architecture
The PEZY-SCnp's architecture is identical to the PEZY-SC.
Cache
PEZY-SC's cache is separate from the ARM926's cache which has an L1$ of 32KB (2x) and 64KB L2$ (shared).
