For example, the measurements on the X220 do not reflect situation on modern Intel systems, as they scale differently from Skylake and newer, as they do not have HWP.
A CPU with HWP (hardware P-states) behaves as you'd expect sort of - it runs at close to max frequency all the time, and scales down extremely in non-performance modes. It scales up and down faster than older models, given that HWP does the frequency scaling inside the CPU. Disabling HWP gives you X220-style old scaling which is slower, and does not go as far down as the HWP scaling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885730 Title: Please switch default, hwe, oem kernel flavours governor to CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y , such that advanced userspace utilities such as game-mode can be later used to rev-up to to performance, or rev-down to powersave.
