Thermal Specifications and Design Considerations
The case temperature is defined at the geometric top center of the processor. Analysis
indicates that real applications are unlikely to cause the processor to consume
maximum power dissipation for sustained time periods. Intel recommends that
complete thermal solution designs target the Thermal Design Power (TDP) indicated in
Table 26 instead of the maximum processor power consumption. The Thermal Monitor
feature is designed to protect the processor in the unlikely event that an application
exceeds the TDP recommendation for a sustained periods of time. For more details on
the usage of this feature, refer to Section 5.2. In all cases the Thermal Monitor or
Thermal Monitor 2 feature must be enabled for the processor to remain within
specification.

NOTES:
1. Thermal Design Power (TDP) should be used for processor thermal solution design targets. The TDP is not the
maximum power that the processor can dissipate.
2. This table shows the maximum TDP for a given frequency range. Individual processors may have a lower TDP.
Therefore, the maximum T will vary depending on the TDP of the individual processor. Refer to Table 28 and
