Saphira is Qualcomm's successor to Falkor, an ARM microarchitecture for the server market.
Process Technology[edit]
Qualcomm has not yet disclosed the process chosen for Saphira but it will most likely be on Samsung's 8nm (DUV) or 7nm (EUV).
Release dates[edit]
Qualcomm first disclosed Saphira at the official launch of the Centriq server family on November 8, 2017.
Architecture[edit]
