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.

AMD's Zen 2 Scheduler Model Gets Partially Fixed Up In LLVM

Landing in the LLVM compiler infrastructure code-base in January was finally an AMD Zen 2 scheduler model optimized for the latest-generation AMD processors when compiling code with Clang using the -march=znver2 targeting. However, now some important fixes to this scheduler model have landed.

AMD Prepares Fix To Address Clicking Issue With Audio Playback On Raven APUs

Unfortunately it wasn't a trouble-free experience at launch but with time Raven Ridge APUs have been getting cleaned up on Linux for a pleasant experience, thanks in part to the Google Chromebook play that has also seen these newer AMD APUs seeing HDCP content protection support and PSP / TEE trusted execution functionality.

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.

The AMD Ryzen Thermal / Power Linux Reporting Improvements Working Well - V2 Up For Testing

A few days ago I reported on AMD's "k10temp" Linux kernel driver finally seeing the ability to report CCD temperatures and CPU current/voltage readings as a big improvement to this hardware monitoring driver. The work hasn't yet been queued for inclusion into the mainline kernel, but initial testing is working well and a second revision to the patches has been sent out.

ASUS TUF Laptops With Ryzen Are Now Patched To Stop Overheating On Linux

The AMD Ryzen Linux laptop experience continues improving albeit quite tardy on some elements of the support. In addition to the AMD Sensor Fusion Hub driver finally being released and current/voltage reporting for Zen CPUs on Linux, another step forward in Ryzen mobile support is a fix for ASUS TUF laptops with these processors.

Benchmarks Of Arch Linux's Zen Kernel Flavor

Following the recent Linux kernel tests of Liquorix and other scheduler discussions (and more), some requests from premium supporters rolled in for seeing the performance of Arch Linux's Zen kernel package against the generic kernel. Here are those benchmark results.

Ryzen CPUs On Linux Finally See CCD Temperatures, Current + Voltage Reporting

One of the few frustrations with the AMD Ryzen CPU support on Linux to date has been besides the often delayed support for CPU temperature reporting has been the mainline kernel not supporting voltage readings and other extra sensors. But that is finally changing with the "k10temp" driver being extended to include current and voltage reporting plus CCD temperature reporting on Zen 2 processors.

AMD Finally Publishes Sensor Fusion Hub Driver For Linux

One of the missing features for those with AMD Ryzen laptops has been the lack of a Sensor Fusion Hub driver that is needed for supporting the accelerometer and gyroscopic sensors for the display and related laptop sensor functionality. This week AMD finally posted patches for a Sensor Fusion Hub Linux driver.

AMD's Trusted Execution Environment Is Coming With Linux 5.6

Last week I wrote about the AMD Secure Processor support for Linux 5.6 being queued as part of the cryptography subsystyem work with supporting the PSP / Secure Processor of Raven Ridge APUs. That AMD Secure Processor support is now rounded out with the Trusted Execution Environment (TEE) driver being queued for wiring into that subsystem.

Linux 5.4.7 / 4.19.92 / 4.14.161 Bringing The AMD MCE Fix For New Threadripper CPUs

With the recently launched Threadripper 3960X / 3970X processors there was a workaround needed to boot them on Linux until an AMD MCE driver issue was resolved. That patch was upstreamed last week into the Linux 5.5 development kernel while now is getting ready to make its debut into supported Linux stable release branches.
