the following factors:

– The number of active cores (in C0 or C1 state)

– The estimated current consumption of the processor (Imax)

– The estimated power consumption (TDP - Thermal Design Power) of processor

– The temperature of the processor

1.3 How to observe Turbo Boost Technology operation in Windows

By using a tool that monitors processor utilization such as Windows Task Manager -

Performance tab, in conjunction with a tool that monitors the CPU frequency such as Intel

Turbo Boost Technology Monitor

(Microsoft* Win7/ Vista) , a user can observe the processor

Turbo Boosted frequency when turbo mode is engaged. In that case, the user can see the

transition of the CPU to the P0 state, at a core frequency that is higher than the marked

frequency of the processor, and can verify that active cores are in turbo mode. For example

using a processor with a 2.6 GHz marked CPU frequency, the user will see a frequency

between 2.67–2.8 GHz when turbo mode is engaged.
