Assured Power (cTDP)
With Assured Power (cTDP), the processor is now capable of altering the maximum sustained power with an alternate processor IA core base frequency. Assured Power (cTDP) allows operation in situations where extra cooling is available or situations where a cooler and quieter mode of operation is desired. Refer to the appropriate processor family BIOS Specification for more enabling details.
cTDP consists of three modes as shown in the following table.
Mode | Description |
---|---|
Processor Base Power | The average power dissipation and junction temperature operating condition limit 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 Configurable Maximum Assured Power configuration. The Maximum Assured Power Frequency and corresponding Processor Base Power (a.k.a TDP) is higher than the processor IA core Base Frequency and SKU Segment Processor Base Power (a.k.a 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 configuration. The Minimum Assured Power Frequency and corresponding Processor Base Power (a.k.a TDP) is lower than the processor IA core Base Frequency and SKU Segment Processor Base Power (a.k.a TDP). |
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 Technology driver assists in Processor Base Power (a.k.a TDP) operation by adjusting processor PL1 dynamically. The Assured Power (cTDP) mode does not change the maximum per-processor IA core turbo frequency.
