PowerNow!
__NOTOC__ 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. The lifetime of the CPU is also extended because of reduced electromigration, which varies exponentially with temperature. AMD.com – TechDocs The technology is a concept similar to Intel's SpeedStep technology. The adaptation of PowerNow! for AMD's desktop CPUs is called Cool'n'Quiet. Newer Opterons also use an adaptation of PowerNow! called ''Optimized Power Management.'' AMD has supplied and supported drivers for its PowerNow! technology that work on Windows 98, ME, NT, and 2000. Processors supporting PowerNow! * K6-2+ * K6-III+ * Athlon XP-M - some models. * Mobile Athlon 64 * Mobile Sempron * Turion 64 and X2 * Athlon II * AMD Accelerated Processing Unit See also * Dynamic frequency scaling Dynamic ...

AMD Turbo Core
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 Turbo Core technology has been implemented beginning with the Phenom II X6 microprocessors based on the AMD K10 microarchitecture. AMD Turbo Core is available with some AMD A-Series accelerated processing units. AMD Turbo Core is similar to Intel Turbo Boost, which is another dynamic processor frequency adjustment technology used to increase performance, as well as AMD PowerNow!, which is used to dynamically adjust laptop processor's operating frequencies in order to decrease power consumption (saving battery life), reduce heat, and lower noise. AMD PowerNow! is used to ''decrease'' processor frequenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cool'n'Quiet
AMD Cool'n'Quiet is a CPU dynamic frequency scaling and power saving technology introduced by AMD with its Athlon XP processor line. It works by reducing the processor's clock rate and voltage when the processor is idle. The aim of this technology is to reduce overall power consumption and lower heat generation, allowing for slower (thus quieter) cooling fan operation. The objectives of cooler and quieter result in the name Cool'n'Quiet. The technology is similar to Intel's SpeedStep and AMD's own PowerNow!, which were developed with the aim of increasing laptop battery life by reducing power consumption. Due to their different usage, ''Cool'n'Quiet'' refers to desktop and server chips, while ''PowerNow!'' is used for mobile chips; the technologies are similar but not identical. This technology was also introduced on "e-stepping" Opterons, however it is called ''Optimized Power Management'', which is essentially a re-tooled Cool'n'Quiet scheme designed to work with reg ...

AMD K6-III
The K6-III (code name: "Sharptooth") was an x86 microprocessor line manufactured by AMD that launched on February 22, 1999. The launch consisted of both 400 and 450 MHz models and was based on the preceding K6-2 architecture. Its improved 256 KB on-chip L2 cache gave it significant improvements in system performance over its predecessor the K6-2. The K6-III was the last processor officially released for desktop Socket 7 systems, however later mobile K6-III+ and K6-2+ processors could be run unofficially in certain socket 7 motherboards if an updated BIOS was made available for a given board. The Pentium III processor from Intel launched 6 days later. At its release, the fastest available desktop processor from Intel was the Pentium II 450 MHz, and in integer application benchmarks a 400 MHz K6-III was able to beat it as the fastest processor available for business applications. Just days later on February 28 Intel released the Pentium III "Katmai" line at speeds of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dynamic Frequency Scaling
Dynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip. Dynamic frequency scaling helps preserve battery on mobile devices and decrease cooling cost and noise on quiet computing settings, or can be useful as a security measure for overheated systems (e.g. after poor overclocking). Dynamic frequency scaling almost always appear in conjunction with dynamic voltage scaling, since higher frequencies require higher supply voltages for the digital circuit to yield correct results. The combined topic is known as dynamic voltage and frequency scaling (DVFS). Operation The dynamic power ('' switching power'') dissipated by a chip is ''C·V2·A·f'', where C is the capacitance being switched per clock cycle, V is voltage, A is the ''acti ...

SpeedStep
Enhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel's microprocessors 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 and heat generation. EIST (SpeedStep III) was introduced in several Prescott 6 series in the first quarter of 2005, namely the Pentium 4 660. Intel Speed Shift Technology (SST) was introduced in Intel Skylake Processor. Enhanced Intel SpeedStep Technology is sometimes abbreviated as EIST. Intel's trademark of "Intel SpeedStep" was canceled due to the trademark being invalidated in 2012. Explanation Running a processor at high clock speeds allows for better performance. However, when the same processor is run at a lower frequency (speed), it gene ...
