ENERGY_PERF_BIAS CFG Mode (ENERGY PERFORMANCE BIAS
CONFIGURATION Mode) (Available when "Power Performance Tuning" is set to
BIOS Controls EPB)
Use this feature to configure the proper operation setting for your machine by achieving
the desired system performance level and energy saving (efficiency) level at the same
time. Select Maximum Performance to maximize system performance to its highest
potential; however, this may consume maximal amount of power as energy is needed to
fuel processor operation. Select Performance to enhance system performance; however,
this may consume more power as energy is needed to fuel the processors for operation.
The options are Maximum Performance, Performance, Balanced Performance, Balanced
Power, and Power.
Optimized Power Mode
Use this feature to enable or disable Optimized Power Mode. The options are Disable and
Enabled.
CPU P State Control
This feature allows you to configure the following CPU power settings:
AVX P1 (Available when "SpeedStep (P-States)" is set to Enable)
Use this feature to set the appropriate TDP level for the system. The Intel Advanced
Vector Extensions (Intel AVX) P1 feature allows you to specify the base P1 ratio for
Streaming SIMD Extensions (SSE) and AVX workloads and to pre-grant a license level.
The options are Nominal, Level 1, and Level 2.
SpeedStep (P-States)
Enhanced Intel SpeedStep Technology (EIST) allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption and heat
dissipation. Refer to Intel's website for detailed information. The options are Disable and
Enable.
EIST PSD Function (Available when "SpeedStep (P-States)" is set to Enable)
This feature reduces the latency that occurs when one P-state changes to another, thus
allowing the transitions to occur more frequently. This feature allows for more demand-
based P-state switching based on real-time energy needs of applications and optimize
the power-to-performance balance for energy efficiency. The options are HW_ALL and
SW_ALL.
