Intel 807 AV8062701079702 Data Sheet

Configurable TDP availability may vary between the different SKUs.

With cTDP, the processor is now capable of altering the maximum sustained power

with an alternate IA core base frequency. Configurable TDP allows operation in

situations where extra cooling is available or situations where a cooler and quieter

mode of operation is desired. Configurable TDP can be enabled using Intel's DPTF

driver or through HW/EC firmware. Enabling cTDP using the DPTF driver is

recommended as Intel does not provide specific application or EC source code.

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

Base

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.

TDP-Up

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 TDP-Up configuration. The Configurable TDP-Up Frequency and

corresponding TDP is higher than the processor IA core Base Frequency and SKU

Segment Base TDP.

TDP-Down

The processor IA core frequency where manufacturing confirms logical functionality

within the set of operating condition limits specified for the SKU segment and

Configurable TDP-Down configuration. The Configurable TDP-Down Frequency and

corresponding TDP is lower than the processor IA core Base Frequency and SKU

Segment Base TDP.

In each mode, the Intel Turbo Boost Technology 2.0 power and frequency ranges are

reprogrammed and the OS is given a new effective HFM operating point. The Intel

DPTF driver assists in all these operations. The cTDP mode does not change the max

per-core turbo frequency.

Low-Power Mode (LPM) can provide cooler and quieter system operation. By

combining several active power limiting techniques, the processor can consume less

power while running at equivalent low frequencies. Active power is defined as

processor power consumed while a workload is running and does not refer to the

power consumed during idle modes of operation. LPM is only available using the Intel

DPTF driver.

Through the DPTF driver, LPM can be configured to use each of the following methods

to reduce active power:
•

Restricting Intel Turbo Boost Power limits and IA core Turbo Boost availability

•

Off-Lining core activity (Move processor traffic to a subset of cores)

•

Placing an IA Core at LFM or LSF (Lowest Supported Frequency)

•

Utilizing IA clock modulation

•

Reducing number of active EUs to GT2 equivalent (Applicable for GT3 SKUs Only)

•

LPM power as listed in the TDP Specifications table is defined at a point which IA

cores working at MFM, GT = RPn and 1 core active
