__NOTOC__
'''AMD PowerNow!''' is [[AMD]]'s [[dynamic frequency scaling]] and power saving technology for [[laptop]] processors.  The [[Central processing unit|CPU]]'s [[clock speed]] and [[VCore]] are automatically decreased when the computer is under low load or idle, to save [[battery (electricity)|battery]] power, reduce heat and [[Quiet PC|noise]].  The lifetime of the CPU is also extended because of reduced [[electromigration]], which varies exponentially with temperature.<ref name="AMD_com_PowerNow!">{{cite web|title=AMD PowerNow!™ Informational White Paper|url=https://www.amd.com/system/files/TechDocs/24404a.pdf|access-date=27 August 2021}} AMD.com – TechDocs</ref>

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 [[Opteron]]s 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.<ref>{{Citation |title=AMD Turion 64 X2 Dual-Core Mobile Technology Utilities & Updates |publisher=[[Advanced Micro Devices]] |url=https://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_14098,00.html |accessdate=2007-04-30}}</ref><ref>{{Citation |title=AMD Turion 64 Mobile Technology Utilities & Updates |publisher=[[Advanced Micro Devices]] |url=https://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_1202_1073%5E871%5E13349,00.html |accessdate=2007-04-30}}</ref>
