This is the same post I made on Reddit but unfortunately I couldn't get much attention. It's seems here is a bit more professional, I am hoping someone can help me, thank you. It's a laptop from Microsoft, Surface Book 2. I run Fedora Linux and Arch Linux, both of them have this issue...
It's a laptop from Microsoft, Surface Book 2. I run Fedora Linux and Arch Linux, both of them have this issue. Either vanilla kernel or surface kernel has the same problem.
I've tried most solution: cpupower tlp thermald throttled power-profiles-daemon intel-pstate s-tui turbostat disable SecureBoot I still cannot get it working.
The CPU is not hot, neither power throttling. I can get it up to 4.2GHz, 35W package on Windows with Throttlestop These digits are What I've never seen on Linux.
It always stays below 2.1GHz, 1.3GHz when all core are stressed, always below 55C. I've made sure, TurboBoost is on.
I've opened these post looking for similar experience, not many responds.
Book2 (15") - No CPU Turbo Boost (always below 2.0GHz)
What's the maximum CPU frequency you can get on Linux with your Surface?
This is the performance I got on Windows
