4.16 Intel® Turbo Boost Technology and AVX
For applications that are particularly power-hungry, the new processors provide enhanced Intel® Turbo Boost technology.
This automatically shifts processor cores and processor graphics resources to accelerate performance, tailoring a
workload to give users an immediate performance boost for their applications whenever needed. Another innovation is
the enhancement to the 256-bit instruction set, known as Intel® Advanced Vector Extensions (AVX). AVX delivers
improved performance, rich functionality and the ability to manage, rearrange and sort data in a better way. The new
instruction set accelerates floating-point intensive applications such as “number crunchers” or digital processing of
images, videos and audio data.
Intel® Turbo Boost Technology 2.0
Intel has optimized Intel® Turbo Boost Technology to provide even more performance when needed on the latest-
generation Intel® microarchitecture. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run
faster than the base operating frequency if it's operating below power, current, and temperature specification limits.
Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor
performance state (P0).
The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. The amount of
time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating
environment. Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:
» Number of active cores
» Estimated current consumption
» Estimated power consumption
» Processor temperature
When the processor is operating below these limits and the user's workload demands additional performance, the
processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology
2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance
and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is
higher than its rated upper power limit (TDP) for short durations to maximize performance.
