Turbo Boost Technology Power Monitoring
When operating in the Turbo mode, the processor will monitor its own power and adjust
the Turbo frequency to maintain the average power within limits over a thermally
significant time period. The package, processor core and graphic core powers are
estimated using architectural counters and do not rely on any input from the platform.

The following considerations and limitations apply to the Intel Turbo Boost Technology
power monitoring:
power monitoring:
• Internal power monitoring is calibrated per processor family and is not conducted
on a part-by-part basis. Therefore, some difference between actual and reported
power may be observed.

• Power monitoring is calibrated with a variety of common, realistic workloads near

. Workloads with power characteristics markedly different from those used
during the calibration process or lower temperatures may result in increased
differences between actual and estimated power.

• In the event an uncharacterized workload or power “virus” application were to
result in exceeding programmed power limits, the processor Thermal Control
Circuitry (TCC) will protect the processor when properly enabled. Adaptive Thermal
Monitor must be enabled for the processor to remain within specification.

Note:
It is recommended to use TCC Activation Offset to optimize thermal control of the
processor while in Turbo. See

Turbo Boost Technology Power Control
Illustration of Intel Turbo Boost Technology power control is shown in the following
sections and figures. Multiple controls operate simultaneously allowing for
customization for multiple system thermal and power limitations. These controls allow
for Turbo optimizations within system constraints and are accessible using MSR, MMIO,
or PECI interfaces.

Package Power Control
Intel Turbo Boost Technology package power control allows for customization in order
to implement optimal Turbo within platform power delivery and package thermal
solution limitations. The control settings are shown in
