random number generation, and authenticated encryption.
Idle States
Idle States (C-states) are used to save power when the processor is
idle. C0 is the operational state, meaning that the CPU is doing useful
work. C1 is the first idle state, C2 the second, and so on, where more
power saving actions are taken for numerically higher C-states.

Intel Secure Key consists of a digital random number generator that
creates truly random numbers to strengthen encryption algorithms.
Intel Speed Shift Technology
Intel Speed Shift Technology uses hardware-controlled P-states to
deliver dramatically quicker responsiveness with single-threaded,
transient (short duration) workloads, such as web browsing, by allowing
the processor to more quickly select its best operating frequency and

data objects. These can include SSE (Streaming SIMD Extensions) and AVX
(Advanced Vector Extensions).
Intel Turbo Boost Max Technology 3.0
Intel Turbo Boost Max Technology 3.0 identifies the best performing
core(s) on a processor and provides increased performance on those cores
through increasing frequency as needed by taking advantage of power and
thermal headroom.
Thermal Monitoring Technologies
Thermal Monitoring Technologies protect the processor package and the
system from thermal failure through several thermal management features.
An on-die Digital Thermal Sensor (DTS) detects the core's temperature,
