'''AMD PowerTune''' is a [[trademark]] for a series of [[dynamic frequency scaling]] technologies built into some [[Advanced Micro Devices|AMD]] [[Graphics processing unit|GPUs]] and [[AMD Accelerated Processing Unit|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 and heat generation. AMD PowerTune aimes at solving Thermal Design Power and Performance Constraints.<ref>{{cite web |url=https://www.amd.com/Documents/amd_powertune_whitepaper.pdf |title=AMD PowerTune Technology |publisher=[[Advanced Micro Devices|AMD]] |format=pdf |date=2012-03-23}}</ref>

Besides the reduced energy consumption, AMD PowerTune helps to lower the noise levels created by the cooling in desktop computers, and extends battery life in mobile devices. AMD PowerTune is the successor to [[AMD PowerPlay]].<ref>{{cite web |url=http://sites.amd.com/uk/Documents/PowerTune_Technology_Whitepaper.pdf |title=AMD PowerTune vs PowerPlay |publisher=[[Advanced Micro Devices|AMD]] |date=2010-12-01 |access-date=13 July 2014 |archive-url=https://web.archive.org/web/20140714171205/http://sites.amd.com/uk/Documents/PowerTune_Technology_Whitepaper.pdf |archive-date=14 July 2014 |url-status=dead }}</ref>
 
Support for "PowerPlay" was added to the Linux kernel driver "amdgpu" on November 11, 2015.<ref>{{cite web |url=http://lists.freedesktop.org/archives/dri-devel/2015-November/094230.html |title=Add amdgpu powerplay support |date=2015-11-11}}</ref>
 
As a lecture from [[Chaos Communication Congress|CCC]] in 2014 shows, AMD's x86-64 SMU firmware is executed on some [[LatticeMico32]] and PowerTune was modeled using Matlab.<ref>{{cite web |url=https://events.ccc.de/congress/2014/Fahrplan/events/6103.html |title=AMD x86 SMU firmware analysis |date=2014-12-27}}</ref> This is similar to Nvidia's PDAEMON, the [[RTOS]] responsible for power on their GPUs.<ref>{{cite web |url=http://phd.mupuf.org/files/ospert13.pdf |title=Reverse engineering power management on Nvidia GPUs}}</ref>
 
== Overview ==
[[File:AMD PowerTune Bonaire.svg|thumb|Architecture of the PowerTune version, that was introduced with [[Graphics Core Next#1.1|GCN1.1]]-chips, such as the Bonaire]]
AMD PowerTune was introduced with [[Radeon HD 6000 Series#Radeon HD 6900|Radeon HD 6900]] in Dec 15, 2010 and has been available in different development stages on [[Radeon]]- and [[AMD FirePro]]-branded products ever since.▼
