Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux

With this week's Ryzen 5 2600X + Ryzen 7 2700X benchmarks some thought the CPUFreq scaling driver or rather its governors may have been limiting the performance of these Zen+ CPUs, so I ran some additional benchmarks this weekend. Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).

OSS Leftovers

• Libjpeg-Turbo 2.0 Beta Brings More AVX2 SIMD, Improved CMake Build System

  A Phoronix reader recently pointed out that LibJPEG 2.0 Beta quietly shipped last month as working towards the next big update for this speed-focused JPEG library. Libjpeg-Turbo 2.0 beta is available for testing and it brings AVX2 SIMD support for colorspace conversion, chroma downsampling/upsampling, integer quantization and sample conversion, and integer DCT/IDCT algorithms. These AVX2 SIMD accelerated paths are generally bringing gains anywhere from 9% to 36% faster depending upon the operation. This version is also bringing SIMD acceleration for Huffman encoding on SSE2 CPUs and Loongson MMI SIMD implementations for more functions.

• A look at Rancher 2.0

  Last December, we announced a Kubernetes Cloud Native Platform in partnership with Rancher Labs. Built on Canonical’s Distribution of Kubernetes and Rancher 2.0, the Cloud Native Platform will simplify enterprise usage of Kubernetes with seamless user management, access control, and cluster administration. Join our webinar to get a tour of the platform!

  Participate in Mozilla's open-source Common Voice Project, an initiative to help teach machines how real people speak: "Now you can donate your voice to help us build an open-source voice database that anyone can use to make innovative apps for devices and the web."

• Collabora Online 3.2 Supports Chart Creation, Other Features

  A new version of Collabora Online is now available, the web-based open-source office suite derived from the cloud version of LibreOffice.

• DragonFlyBSD Kernel Gets Some SMP Improvements

  It looks like the DragonFlyBSD 5.4 release will be delivering at least a few kernel-level performance improvements. It turns out just hours after wrapping up the latest BSD vs. Linux benchmarks, Matthew Dillon pushed a few performance tweaks to the Git tree for DragonFly.

• Best Open Source 3D Printers

  In simplest terms, an open source 3D printer refers to a 3D printer whose hardware and software information are available to the public, typically under a license. The information can be used by anyone to build, modify, or improve the 3D printer. If you’re looking for real open source 3D printers, then you’ve come to the right place. In this guide, we introduce you to completely open source 3D printers. The hardware and software information of all the products listed here can be easily found on the internet.
