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 T

The Intel Thermal Monitor automatic mode must be enabled for the processor to operate within
specifications.
