The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the activity factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
The Linux kernel has a subsystem called "cpufreq", tunable by power-scheme and command line, devoted to the control of the operating frequency and voltage of a CPU. Linux runs on Intel, AMD, and other makes of CPU. [13] [14] Newer version Windows 10 and Linux kernel support Intel Speed Shift Technology.
Likewise, Linux distributions include a variety of power management settings and tools. [5] There is a significant market in third-party PC power management software offering features beyond those present in the Windows operating system. [6] [7] [8] Notable vendors Data Synergy's 'PowerMAN', [9] Faronics' 'Power Save', [10] [11] and Verdiem's ...
Arm MAP, a performance profiler supporting Linux platforms. AppDynamics, an application performance management solution [buzzword] for C/C++ applications via SDK. AQtime Pro, a performance profiler and memory allocation debugger that can be integrated into Microsoft Visual Studio, and Embarcadero RAD Studio, or can run as a stand-alone application.
PowerToys for Windows 95 was the first version of Microsoft PowerToys and included 15 tools for power users. It included Tweak UI, a system utility for tweaking the more obscure settings in Windows. In most cases, Tweak UI exposed settings that were otherwise only accessible by directly modifying Windows Registry. [4]
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
Additionally, processors can selectively power off internal circuitry (power gating). For example: Newer Intel Core processors support ultra-fine power control over the functional units within the processors. AMD CoolCore technology get more efficient performance by dynamically activating or turning off parts of the processor. [3]
Windows Media Decoding Performance; Windows Media Encoding Performance; CPU Performance; Memory Performance; Disk Performance (includes devices such as Solid-state drives) While running, the tests show only a progress bar and a "working" background animation. Aero Glass is deactivated on Windows Vista and Windows 7 during testing so the tool ...
