Turbo Time Parameter is a mathematical parameter (units in seconds) that controls

the Intel Turbo Boost Technology 2.0 algorithm using moving average of energy

usage. During a maximum power turbo event of about 1.25 x TDP, the processor

could sustain PL2 for up to approximately 1.5 times the Turbo Time Parameter. If the

power value and/or Turbo Time Parameter is changed during runtime, it may take

approximately 3 to 5 times the Turbo Time Parameter for the algorithm to settle at the

new control limits. The time varies depending on the magnitude of the change and

other factors. There is an individual Turbo Time Parameter associated with Package

Power Control.

Configurable TDP (cTDP) and Low-Power Mode (LPM) form a design vector where the

processor's behavior and package TDP are dynamically adjusted to a desired system

performance and power envelope. Configurable TDP and Low-Power Mode

technologies offer opportunities to differentiate system design while running active

workloads on select processor SKUs through scalability, configuration and adaptability.

The scenarios or methods by which each technology is used are customizable but

typically involve changes to PL1 and associated frequencies for the scenario with a

resultant change in performance depending on system's usage. Either technology can

be triggered by (but are not limited to) changes in OS power policies or hardware

events such as docking a system, flipping a switch or pressing a button. cTDP and LPM

are designed to be configured dynamically and do not require an operating system

reboot.

Configurable TDP and Low-Power Mode technologies are not battery life improvement

technologies.
