Intel SpeedStep Technology

Intel SpeedStep technology allows processors to switch between multiple frequen- cies and voltage points for better power saving and heat dissipation.

Intel Turbo Boost Technology

Intel Turbo Boost Technology enables the processor to run above its base operating frequency when the operating system requests the highest performance state.
