Off-lining core activity is the ability to dynamically scale a workload to a limited subset
of cores in conjunction with a lower turbo power limit. It is one of the main vectors
available to reduce active power. However, not all processor activity is ensured to be
able to shift to a subset of cores. Shifting a workload to a limited subset of cores
allows other cores to remain idle and save power. Therefore, when LPM is enabled,
less power is consumed at equivalent frequencies.
Minimum Frequency Mode (MFM) of operation, which is the lowest supported
frequency (LSF) at the LFM voltage, has been made available for use under LPM for
further reduction in active power beyond LFM capability to enable cooler and quieter
modes of operation.

Note
Definition
1
The TDP and Configurable TDP values are the average power dissipation in junction temperature operating
condition limit, 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.
2
TDP workload may consist of a combination of processor-core intensive and graphics-core intensive applications.
3
The thermal solution needs to ensure that the processor temperature does not exceed the maximum junction
temperature (Tj
MAX
) limit, as measured by the DTS and the critical temperature bit.
4
The processor junction temperature is monitored by Digital Temperature Sensors (DTS). For DTS accuracy, refer to
5
At Tj of Tj
MAX
6
Can be modified at runtime by MSR writes, with MMIO and with PECI commands.
7
'Turbo Time Parameter' is a mathematical parameter (unit in seconds) that controls the processor turbo algorithm
using a moving average of energy usage. Do not set the Turbo Time Parameter to a value less than 0.1 seconds.
Refer to
on page 62 for further information.
8
Shown limit is a time averaged power, based upon the Turbo Time Parameter. Absolute product power may exceed
the set limits for short durations or under virus or uncharacterized workloads.
9
on page 61. If the power value and/or 'Turbo Time Parameter' is changed during runtime, it may take a
short period of time (approximately 3 to 5 times the 'Turbo Time Parameter') for the algorithm to settle at the new
control limits.
10
This is a hardware default setting and not a behavioral characteristic of the part.
11
For controllable turbo workloads, limit may be exceeded for up to 10 ms.
12
Refer to
on page 63 for the definitions of 'base', 'TDP-Up' and 'TDP-Down'.
13
LPM power level is an opportunistic power and is not a guaranteed value as usages and implementations may vary.
14
Power limits may vary depending on if the product supports the 'TDP-up' and/or 'TDP-down' modes. Default power
limits can be found in the PKG_PWR_SKU MSR (614h).
15
May vary based on SKU.
16
Hardware default values might be overridden by the BIOS.
