AMD PowerTune

October 14, 2023

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 generation and noise avoidance. AMD PowerTune aims to solve thermal design power and performance constraints.[1]

AMD PowerTune
Design firmAdvanced Micro Devices
IntroducedDecember 2011
TypeDynamic frequency scaling

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.[2]

Support for "PowerPlay" was added to the Linux kernel driver "amdgpu" on November 11, 2015.[3]

As a lecture from CCC in 2014 shows, AMD's x86-64 SMU firmware is executed on some LatticeMico32 and PowerTune was modeled using Matlab.[4] This is similar to Nvidia's PDAEMON, the RTOS responsible for power on their GPUs.[5]

Overview Edit

 
Architecture of the PowerTune version, that was introduced with GCN1.1-chips, such as the Bonaire

AMD PowerTune was introduced in the TeraScale 3 (VLIW4) with Radeon HD 6900 on 15 December 2010 and has been available in different development stages on Radeon- and AMD FirePro-branded products ever since.

Over the years, reviews which document the development of AMD PowerTune have been published by AnandTech.[6][7][8][9]

An additional technology named AMD ZeroCore Power has been available since the Radeon HD 7000 Series, implementing the Graphics Core Next microarchitecture.

The pointlessness of a fixed clock frequency was accredited in January 2014 by SemiAccurate.[10]

Operating system support Edit

 
Support for PowerTune is contained in the Linux kernel device driver amdgpu.

AMD Catalyst is available for Microsoft Windows and Linux and supports AMD PowerTune since version.[which?]

The free and open-source "Radeon" graphics device driver has some support for AMD PowerTune, see "Enduro".[11]

  1. ^ The Radeon 100 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0. See article on R100's pixel shaders.
  2. ^ R300, R400 and R500 based cards do not fully comply with OpenGL 2+ as the hardware does not support all types of non-power of two (NPOT) textures.
  3. ^ OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
  4. ^ a b c The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
  5. ^ Video processing for video frame rate interpolation technique. In Windows it works as a DirectShow filter in your player. In Linux, there is no support on the part of drivers and / or community.
  6. ^ a b To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
  7. ^ More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
  8. ^ a b DRM (Direct Rendering Manager) is a component of the Linux kernel. AMDgpu is the Linux kernel module. Support in this table refers to the most current version.

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 generation and noise avoidance AMD PowerTune aims to solve thermal design power and performance constraints 1 AMD PowerTuneDesign firmAdvanced Micro DevicesIntroducedDecember 2011TypeDynamic frequency scalingBesides 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 2 Support for PowerPlay was added to the Linux kernel driver amdgpu on November 11 2015 3 As a lecture from CCC in 2014 shows AMD s x86 64 SMU firmware is executed on some LatticeMico32 and PowerTune was modeled using Matlab 4 This is similar to Nvidia s PDAEMON the RTOS responsible for power on their GPUs 5 Contents 1 Overview 2 Operating system support 2 1 Feature overview for AMD APUs 2 2 Feature overview for AMD

the TeraScale 3 VLIW4 with Radeon HD 6900 on 15 December 2010 and has been available in different development stages on Radeon and AMD FirePro branded products ever since Over the years reviews which document the development of AMD PowerTune have been published by AnandTech 6 7 8 9 An additional technology named AMD ZeroCore Power has been available since the Radeon HD 7000 Series implementing the Graphics Core Next microarchitecture The pointlessness of a fixed clock frequency was accredited in January 2014 by SemiAccurate 10 Operating system support Edit nbsp Support for PowerTune is contained in the Linux kernel device driver amdgpu AMD Catalyst is available for Microsoft Windows and Linux and supports AMD PowerTune since version which The free and open source Radeon graphics
