  • Car Makers Rev Up Automotive Grade Linux at CES

    The hottest up-and-coming auto show may very well be CES. Many of the world’s biggest automakers will be there, and they’ll be showing off more than new electric or self-driving cars. The technology inside our cars for music, infotainment, and GPS is also a big part of story. Especially with consumers expecting their “connected” car experience to be as glitzy, convenient, simple and easy to upgrade as their smart phone or wearable.

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).
