Undervolt

Reduce the voltage suppiled to the processor

A reduced voltage decreases power consumption and thermal output of the processor - improving battery life

Preventing thermal throtteling - allowing longer sustained performance

Undervolting is only compatible with Haswell and Broadwell processors (Macbooks from 2013 - 2015). This functionality has been prevented on later generations.

Turbo Boost

Disable the automatic overclock to save power when performance is not of priority

Power Limit

Set a definitive power limit, constraining the CPU to perform within a set power boundry
