An Initial Look at the IBM POWER9 4c/16t CPU Performance on the Blackbird

A few weeks ago we received a POWER9 Raptor Blackbird for testing that features an IBM POWER9 4-core (16 thread) processor clocked at 3.80GHz. For those curious about the performance potential for low-end POWER9 parts compared to the more common high-core/thread count POWER processors we have benchmarked before like in the Talos II server, here are some initial tests of that petite POWER9 processor. The CPU vulnerability mitigations were at their defaults and in the case of the POWER9 set to the less strict kernel protection only mode (more details in our Blackbird speculative execution testing).
