Package Power Control
The package power control settings of PL1, PL2, PL3, PL4, and Tau allow the designer to configure Intel® Turbo Boost Technology 2.0 to match the platform power delivery and package thermal solution limitations.
- Power Limit 1 (PL1): A threshold for average power that will not exceed - recommend to set to equal Processor Base Power (a.k.a TDP). PL1 should not be set higher than thermal solution cooling limits.
- Power Limit 2 (PL2): A threshold that if exceeded, the PL2 rapid power limiting algorithms will attempt to limit the spike above PL2.
- Power Limit 3 (PL3): A threshold that if exceeded, the PL3 rapid power limiting algorithms will attempt to limit the duty cycle of spikes above PL3 by reactively limiting frequency. This is an optional setting
- Power Limit 4 (PL4): A limit that will not be exceeded, the PL4 power limiting algorithms will preemptively limit frequency to prevent spikes above PL4.
- Turbo Time Parameter (Tau): An averaging constant used for PL1 exponential weighted moving average (EWMA) power calculation.
- Implementation of Intel® Turbo Boost Technology 2.0 only requires configuring PL1, PL1, Tau and PL2.
- PL3 and PL4 are disabled by default.
- The Intel Dynamic Tuning (DTT) is recommended for performance improvement in mobile platforms. Dynamic Tuning is configured by system manufacturers dynamically optimizing the processor power based on the current platform thermal and power delivery conditions.
