POWER8E (also known as POWER8 with NVLink, POWER8’ (with a prime symbol), 8335-GTB POWER8, or POWER8+) processors have a different socket than standard POWER8 chips.
Compared to a standard POWER8 Single Chip Module (SCM), the POWER8 with NVLink modifies:
- 2nd CAPP unit added, X2 removed
- x8 PHB
- x8 IOP
- A-bus removed, NVLink added
- NVLink support added in extended ES
- Chip height: 2 C4 rows added
Without A-bus or SMP over PCIe, the processors in a multisocket configuration instead use X-Bus for SMP. The chip size is 659 mm2, rather than 649 mm2 for POWER8, and only available for the S822LC for HPC, specifically the 8335-GTB model. [1][2]
