What is Intel® Turbo Boost Technology and how does it work?
Intel® Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the thermal design power (TDP). This results in increased performance of both single and multi-threaded applications.

The chart below illustrates how Intel Turbo Boost Technology works across the Processor cores if adequate power, temperature, and current headroom exists.
