NOTES:
1.
The TDP specification should be used to design the processor thermal solution. The TDP is
not the maximum theoretical power the processor can generate.
2.
Not 100% tested. These power specifications are determined by characterization of the
processor currents at higher temperatures and extrapolating the values for the
temperature indicated.
3.
As measured by the activation of the on-die Intel Thermal Monitor. The Intel Thermal
Monitor’s automatic mode is used to indicate that the maximum TJ has been reached.
Refer to Section 5.1 for more details.
4.
The Intel Thermal Monitor automatic mode must be enabled for the processor to operate
within specifications.
