Turbo Boost is an Intel feature designed to pack more processing power into a computer chip for use when you need it. For most tasks, your Mac’s CPU maxes out at its base processing speed, say 2.7GHz. When the computer senses more processing power is needed, it can enable Turbo Boost to temporarily speed up the CPU, say to 3.6GHz.
Turbo Boost Switcher allows you to turn Turbo Boost on or off whenever you like. That way, whether you’re writing an email or editing a video in Final Cut Pro, your Mac’s CPU will never push above it’s base clock speed. This simple change can save hours of battery life and keep your laptop cool and fan speeds low. To let you know for sure how it’s working, Turbo Boost Pro allows you to monitor CPU speeds and temperatures at all times.
Turbo Boost Switcher claims to reduce battery usage by up to 25%, and CPU temperatures by 20%, though it only cites a 2015 blog post as evidence.
