Assured Power (cTDP) Modes

Note:Assured Power availability may vary between the different SKUs.

With cTDP, the processor is now capable of altering the maximum sustained power with an alternate processor IA core base frequency. Assured Power allows operation in situations where extra cooling is available or situations where a cooler and quieter mode of operation is desired.

cTDP consists of three modes as shown in the following table.

Description

Base

The average power dissipation and junction temperature operating condition limit, is specified in Table: Processor Base Power (TDP) Specifications (H-Series Processor) , Table: Processor Base Power Specifications (U-Series Processor) . For the SKU Segment and Configuration, for which the processor is validated during manufacturing when executing an associated Intel-specified high-complexity workload at the processor IA core frequency corresponding to the configuration and SKU.

Maximum Assured Power

The SKU-specific processor IA core frequency where manufacturing confirms logical functionality within the set of operating condition limits specified for the SKU segment and Maximum Assured Power (cTDP UP) configuration in Table: Processor Base Power (TDP) Specifications (H-Series Processor) , Table: Processor Base Power Specifications (U-Series Processor) . The Maximum Assured Power (a.k.a. cTDP UP) Frequency and corresponding Processor Base Power is higher than the processor IA core Base Frequency and SKU Segment Base TDP.

Minimum Assured Power

The processor IA core frequency where manufacturing confirms logical functionality within the set of operating condition limits specified for the SKU segment and Configurable Minimum Assured Power (cTDP Down) configuration in Table: Processor Base Power (TDP) Specifications (H-Series Processor) . The Minimum Assured Power (cTDP Down) Frequency and corresponding Processor Base Power is lower than the processor IA core Base Frequency and SKU Segment Processor Base Power.

In each mode, the Intel® Turbo Boost Technology 2.0 power limits are reprogrammed along with a new OS controlled frequency range. The Intel Dynamic Tuning driver assists in Processor Base Power operation by adjusting processor PL1 dynamically. The cTDP mode does not change the maximum per-processor IA core turbo frequency.
