Honestly, Power9 is not really powerful compared to Milan; it's 1/3 to 1/2 the performance at best. https://openbenchmarking.org/vs/Processor/AMD%20EPYC%207763%...

The desktop-grade Power9 gets rekt by a Core i3: https://openbenchmarking.org/vs/Processor/POWER9%204-Core,In...

The advantage of POWER9 is fully open firmware and hardware while being really powerful. They won't beat the latest AMD in performance. But AMD can never be open. The RaptorCS products are FSF RYF (respects your freedom) certified.
