Notes:
1. These values specify the power consumption at nominal voltage and apply to all valid processor bus frequencies and
configurations. The values do not include power dissipation for I/O supplies.
2. Typical power is an average value measured at the nominal recommended core voltage (VDD_Core) and 65°C junction
temperature (see
Table 3) while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz with the core
at 100% efficiency. This parameter is not 100% tested but periodically sampled.
3. Thermal power is the average power measured at nominal core voltage (VDD_Core) and maximum operating junction
temperature (see
Table 3) while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz on the core
and a typical workload on platform interfaces. This parameter is not 100% tested but periodically sampled.
4. Maximum power is the maximum power measured at nominal core voltage (VDD_Core) and maximum operating junction
temperature (see
Table 3) while running a test which includes an entirely L1-cache-resident, contrived sequence of
instructions which keep all the execution units maximally busy on the core.
