Turbo Boost Technology Frequency
The processor’s rated frequency assumes that all execution cores are running an
application at the thermal design power (TDP). However, under typical operation, not
all cores are active. Therefore, most applications are consuming less than the TDP at
the rated frequency. To take advantage of the available thermal headroom, the active
cores can increase their operating frequency.

all cores are active. Therefore, most applications are consuming less than the TDP at
the rated frequency. To take advantage of the available thermal headroom, the active
cores can increase their operating frequency.
To determine the highest performance frequency amongst active cores, the processor
takes the following into consideration:
takes the following into consideration:
• The number of cores operating in the C0 state.
• The estimated current consumption.
• The estimated power consumption.
• The temperature.
• The estimated current consumption.
• The estimated power consumption.
• The temperature.
Any of these factors can affect the maximum frequency for a given workload. If the
power, current, or thermal limit is reached, the processor will automatically reduce the
frequency to stay with its TDP limit.
power, current, or thermal limit is reached, the processor will automatically reduce the
frequency to stay with its TDP limit.
Note:
Intel Turbo Boost Technology processor frequencies are only active if the operating
system is requesting the P0 state. For more information on P-states and C-states, refer

Turbo Boost Technology Graphics Frequency
Graphics render frequency is selected by the processor dynamically based on graphics
workload demand. The processor can optimize both processor and Processor Graphics
performance by managing power for the overall package. For the Processor Graphics,
this allows an increase in the render core frequency and increased graphics
performance for graphics intensive workloads. In addition, during processor intensive
workloads when the graphics power is low, the processor core can increase its
frequency higher within the package power limit. Enabling Intel Turbo Boost Technology
will maximize the performance of the processor core and the graphics render frequency
within the specified package power levels.
