Thermal Specifications
Notes:
1. Thermal Profile A is representative of a volumetrically unconstrained platform. Please refer to Table 6-5 for
discrete points that constitute the thermal profile.
2. Implementation of Thermal Profile A should result in virtually no TCC activation. Furthermore, utilization of
thermal solutions that do not meet processor Thermal Profile A will result in increased probability of TCC
activation and may incur measurable performance loss. (Refer to Section 6.2 for details on TCC activation).
3. Thermal Profile B is representative of a volumetrically constrained platform. Please refer to Table 6-6 for
discrete points that constitute the thermal profile.
4. Implementation of Thermal Profile B will result in increased probability of TCC activation and measurable
performance loss. Furthermore, utilization of thermal solutions that do not meet Thermal Profile B do not
meet the processor’s thermal specifications and may result in permanent damage to the processor.
5. Refer to the Dual-Core Intel

TCASE_MAX is a thermal solution design point. In actuality, units will not significantly exceed
TCASE_MAX_A due to TCC activation.
