intel i7 data sheet3.4 Intel® Turbo Boost TechnologyIntel Turbo Boost Technology is a feature that allows the processor to opportunistically and automatically run faster than its rated operating frequency if it is operating below power, temperature, and current limits. The result is increased performance in multi- threaded and single threaded workloads. It should be enabled in the BIOS for the processor to operate with maximum performance.3.4.1 Intel Turbo Boost Technology Processor FrequencyThe processors rated frequency assumes that all execution cores are running an application at the thermal design power (TDP). However, under typical operation, not all cores are active. Therefore most applications are consuming less than the TDP at the rated frequency. To take advantage of the available TDP headroom, the active cores can increase their operating frequency.To determine the highest performance frequency amongst active cores, the processor takes the following into consideration: The number of cores operating in the C0 state. The estimated current consumption. The estimated power consumption. The temperature.Any of these factors can affect the maximum frequency for a given workload. If the power, current, or thermal limit is reached, the processor will automatically reduce the frequency to stay with its TDP limit.Intel Turbo Boost Technology processor frequencies are only active if the operating system is requesting the P0 state. For more information on P-states and C-states refer to Chapter 4, Power Management.

met dezelfde processor tijdens dezelfde test op 80 °C bleef steken kwam de processor van de MacBook Pro op 100 °C uit.
