AMD PowerPlay

From Wikipedia, the free encyclopedia

Brand name by AMD
AMD PowerPlay
Design firmAdvanced Micro Devices
TypeDynamic frequency scaling

AMD PowerPlay is the brand name for a set of technologies for the reduction of the energy consumption implemented in several ofAMD'sgraphics processing units andAPUs supported by theirproprietarygraphics device driver "Catalyst". AMD PowerPlay is also implemented intoATI/AMD chipsets which integrated graphics and into AMD'sImageon handheld chipset, that was sold toQualcomm in 2008.

Besides the desirable goal to reduce energy consumption, AMD PowerPlay helps to lower the noise levels created by the cooling in desktop computers and extend battery life in mobile devices. AMD PowerPlay has been succeeded byAMD PowerTune.[1]

History

[edit]

The technology was first implemented in Mobility Radeon products for notebooks, to provide a set of features to lower the power consumption of the laptop computer. The technology consists of several technologies; examples includedynamic clock adjustments when the notebook is not plugged into a power socket and allowing different backlight brightness levels of the notebookLCD monitor. The technology was updated with the release of each generation of mobile GPUs. The latest release is ATI PowerPlay 7.0.[2]

Since the release ofRadeon HD 3000 Series, PowerPlay was implemented to further reduce the power consumption of desktop GPUs.

Supported products

[edit]

The official ATI support list[3] lists only the ATI Radeon 3800 series desktop cards, but PowerPlay is also a listed feature of all Radeon HD 3000/4000/5000 series products. Independent reviews indicated that the latter was already lower power compared to other 3D cards, so the addition of PowerPlay to that line was clearly intended to address an increasingly power, heat and noise conscious market. The ATI Radeon HD 2600 line – which does not support PowerPlay – was being phased out in favour of the 3000 series at the same price points that also supportPCI Express 2.0,DirectX 10.1 and fasterGDDR3 memory.

The entireATI Radeon Xpress line is also supported forsingle board computers which tend to be power sensitive and used in large installations where configuration andboot image control are major concerns.

Support for "PowerPlay" was added to the Linux kernel driver "amdgpu" on November 11, 2015.[4]

Desktop versus laptop

[edit]

The main difference between the desktop and laptop versions is that the desktop version cuts the features which are aimed at notebook usage, including variable LCD backlight brightness. The PowerPlay technology for Radeon desktop graphics features three usage scenarios: normal mode (2D mode), light gaming mode and intensive gaming mode (3D mode), replacing notebook scenarios (running on AC power or battery power). Tests indicated that the lowest core clock frequency of an RV670 GPU core can reach as low as 300MHz with PowerPlay technology enabled.[5]

  1. ^The Radeon 100 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0. See article onR100'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. ^abOpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
  4. ^Vulkan support is theoretically possible but has not been implemented in a stable driver.
  5. ^Vulkan support in Linux relies on the amdgpu kernel driver which is incomplete and not enabled by default for GFX6 and GFX7.
  6. ^abcThe UVD and VCE were replaced by the Video Core Next (VCN) ASIC in theRaven Ridge APU implementation of Vega.
  7. ^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.
  8. ^abTo 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.
  9. ^More displays may be supported with nativeDisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
