2.2.3 Performance Targets
The Thermal Profile specification for this processor is published in the 64-bit Intel
®
Xeon™
Processor MP with up to 8 MB L3 Cache Datasheet. The Thermal Profile specification is shown as
a reference in the subsequent discussions.

NOTE: The thermal specification shown in this graph is for reference only. Refer to the 64-bit Intel
®
Xeon™
Processor MP with up to 8 MB L3 Cache Datasheet for the Thermal Profile specification. In case of
conflict, the data information in the datasheet supersedes any data in this figure.
Table 2-2 describes thermal performance targets for the processor cooling solution enabled by Intel.
