Intel® Turbo Boost Technology1 provides more performance when needed on 4th generation Intel® Core™ processor-based systems. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the base operating frequency if they’re operating below power, current, and temperature specification limits.

Dynamically increasing performance
Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor performance state (P0).

The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.

Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:

Number of active cores
Estimated current consumption
Estimated power consumption
Processor temperature
