AMD PowerNow! is AMD's dynamic frequency scaling and power saving technology for laptop processors. The CPU 's clock speed and VCore are automatically decreased when the computer is under low load or idle, to save battery power, reduce heat and noise .
AMD PowerTune is a series of dynamic frequency scaling technologies built into some AMD GPUs and APUs that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw, heat ...
Set in 2011, the Guinness World Record for the highest CPU clock rate is 8.42938 GHz with an overclocked AMD FX-8150 Bulldozer-based chip in an LHe/LN2 cryobath, 5 GHz on air. [ 5 ] [ 6 ] This is surpassed by the CPU-Z overclocking record for the highest CPU clock rate at 8.79433 GHz with an AMD FX-8350 Piledriver -based chip bathed in LN2 ...
ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...
time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
Radeon Software 17.7.1 is the final driver for Windows 8.1. Radeon Software 18.9.3 is the final driver for 32-bit Windows 7/10. AMD Software 22.6.1 is the final driver for Windows 7 (and Windows 8.1 unofficially); 22.6.1 is also the final driver for GCN 1, GCN 2 and GCN 3 based GPUs [42]
AMD Turbo Core a.k.a. AMD Core Performance Boost (CPB) is a dynamic frequency scaling technology implemented by AMD that allows the processor to dynamically adjust and control the processor operating frequency in certain versions of its processors which allows for increased performance when needed while maintaining lower power and thermal parameters during normal operation.

AMD PowerPlay is the brand name for a set of technologies for the reduction of the energy consumption implemented in several of AMD's graphics processing units and APUs supported by their proprietary graphics device driver "Catalyst".
