Noctua NH-U9S Performance For The AMD Ryzen 9 3950X + Ondemand vs. Performance Governors

For those that may be looking to run an air-cooled AMD Ryzen 9 3950X especially in a rack-mount 4U chassis, here are some recent results I did from some testing using a Noctua NH-U9S with two 92mm fan configuration. Additionally, these results contain performance metrics from both CPUFreq Ondemand vs. Performance governors as an additional point of interest.

CPUs From 2004 Against AMD's New 64-Core Threadripper 3990X + Tests Against FX-9590

With having the initial AMD Ryzen Threadripper 3990X Linux benchmarks out of the way, I did some fun Friday night benchmarking with this 64-core HEDT CPU... Seeing how the 3990X performance compares to some CPUs used when starting out Phoronix back in 2004 as well as also for fun seeing how the Threadripper 3990X compares to the notorious AMD FX-9590.

Linux k10temp Driver For AMD CPUs Updated To Better Handle Power/Temp Analysis

As we have been eagerly talking about for the past week, the Linux kernel's k10temp driver was updated for better AMD CPU CCD temperatures and voltage/current reporting. Those improvements have been quickly evolving thanks to the work of the open-source community with AMD still sadly holding the datasheets concerning the power/temperature registers close to their vest. A new version of k10temp was sent out on Wednesday.
