For more general information about the Nimbus chip this module contains, such as details about particular steppings, please see Nimbus.

Sforza is the codename for a POWER9, Nimbus chip, CPU module/package designed for general purpose computing, with high I/O available over standard PCIe generation 4 interfaces. The Nimbus chip it houses has 24 cores on the die, each capable of SMT4, and as a Scale Out processor intended for dual socket systems, uses directly attached RAM.

It is used by the Talos™ II systems.

Configurations

As with many CPUs, Nimbus-Sforza modules can be sold with some number of CPU cores disabled, and with different default clock speeds; at this time, no known Nimbus-Sforza parts are available with all 24 cores enabled.
