AMD PowerTune is a trademark for 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. AMD PowerTune aims to solve thermal design power and performance constraints. Support for "PowerPlay" was added to the Linux kernel driver "amdgpu" on November, 11 2015.

dbo:abstract
  • AMD PowerTune is a trademark for 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. AMD PowerTune aims to solve thermal design power and performance constraints. 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. Support for "PowerPlay" was added to the Linux kernel driver "amdgpu" on November, 11 2015. As a lecture from CCC in 2014 nicely shows, AMD's x86-64 SMU firmware is executed on some LatticeMico32 and PowerTune was modeled using Matlab. This is similar to Nvidia's PDAEMON, the RTOS responsible for power on their GPUs. (en)
