You just need to write 1 to /sys/devices/system/cpu/intel_pstate/no_turbo , like in sudo sh -c 'printf 1 > /sys/devices/system/cpu/intel_pstate/no_turbo' Writing 0 re-enables turbo. Note it is not the same as the power-saving mode in Gnome settings under the Power section. This is more similar to Low-power mode in MacOS which also prevents Turbo boost. EDIT: I was wrong to call it power-saving mode in the grandparent comment. It should be called no-turbo mode there.
