  • Linaro to Release Open-Source Software Platform for ARM Servers

    The group hopes its reference software platform will help accelerate the adoption of ARM-based systems in the data center to challenge Intel.
    When talking about ARM-based processors running in servers and other data center systems, the challenge has been as much getting the necessary software and ecosystem support together as it has ensuring the chips can handle the workloads.

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).
