Power & Performance
Scenario
Balanced
x
The CPU clock is dynamically limited with maximum 3D
graphics performance.
The maximum CPU power consumption is 17 W.
Max Performance
Setting for highest performance of CPU and graphics at
the same time.
The maximum CPU power consumption is 25 W.
High Temperature
Setting for lowest power consumption. The CPU clock is
limited at a higher load.
The maximum power consumption of the CPU is 12 W.
Stable Performance
Same as Balanced, but additionally optimized for stable
operation with constant CPU frequency.
The maximum CPU power consumption is 17 W.
Intel(R) SpeedStep(tm)
Disabled
The use of more than two frequency ranges is disabled.
Enabled
x
The use of more than two frequency ranges is enabled.
Intel(R) Speed Shift Tech-
nology
Disabled
Intel® Speed Shift Technology is disabled.
Enabled
x
Intel® Speed Shift Technology is enabled.
HDC Control
Disabled
HDC Control (Hardware Duty Cycle Control) is disabled.
Enabled
x
HDC Control (Hardware Duty Cycle Control) is enabled
(if supported by the operating system).
• Turbo Mode
(only if the processor
type used supports
turbo mode)
(only when "Intel(R)
SpeedStep(tm)" = En-
abled)
Disabled
Turbo mode is disabled.
Enabled
x
Turbo mode is enabled.
When the operating system requires more power, the
processor can use Intel® Turbo Boost Technology to
increase the clock speed. To use turbo mode effective-
ly, the performance modes of the "Intel(R) Speed-
Step(tm)"/"Intel (R) Speed Shift Technology" processor
and the power saving modes of the "C states" processor
must be enabled.
C states
Disabled
The energy-saving modes of the "C states" processor
are disabled.
Enabled
x
The energy-saving modes of the "C states" processor
are enabled.
