Dual Thermal Profile
Processors that offer dual thermal profile are specified in the appropriate Datasheet.
Dual thermal profile helps mitigate limitations in volumetrically constrained form
factors and allows trade-offs between heatsink cost and TCC activation risk. For
heatsinks that comply to Profile B, yet do not comply to Profile A (1U heatsink in
factors and allows trade-offs between heatsink cost and TCC activation risk. For
heatsinks that comply to Profile B, yet do not comply to Profile A (1U heatsink in
), the processor has an increased probability of TCC activation and an
associated measurable performance loss. Measurable performance loss is defined to be
any degradation in processor performance greater than 1.5%. 1.5% is chosen as the
baseline since run-to-run variation in a performance benchmark is typically between 1
and 2%.
