Energy Efficient Turbo (EET) is a mode of operation where a processor’s core frequency is adjusted to be within
the turbo range based on workload.

The optimization of the uncore frequency to either save power or optimize performance is influenced by the
setting of the
Energy Efficiency Policy option.
Energy Efficient
Policy

The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to target
higher performance or better power savings.
