ATI PowerPlay is a collective name for a set of technologies implemented in a series graphics adapters manufactured by ATI, including Mobility Radeon, Imageon handheld chipset and Radeon family of desktop GPUs.
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 include dynamic clock adjustments when the notebook is not plugged into a socket and allowing different backlight brightness levels of the notebook LCD monitor. The technology was updated with the release of each generation of mobile GPUs. The latest release is the ATI PowerPlay 7.0.
The Radeon HD 3800 series had seen the implementation of the PowerPlay technology on desktop to further reduce the power consumption of the GPU.
The main differences between the desktop version and the mobile version is that the desktop version cut the feature which were aimed at notebook usages, including variable LCD backlight brightness, leaving dynamic clock adjustments. The PowerPlay technology for Radeon desktop graphics also used three usage scenarios, accordingly the normal mode (2D mode), light gaming mode and intensive gaming mode (3D mode), replacing usage scenarios in notebook (being plugged or unplugged from AC source). Tests indicated that the lowest core clock frequency of an RV670 GPU core can reach as low as 300 MHz with PowerPlay technology enabled. [1]
