PowerNow
PowerNow! is AMD's branding for its dynamic voltage and frequency scaling (DVFS) technology used in mobile processors to balance performance and power consumption. By adjusting the processor’s clock speed and core voltage in response to workload and thermal conditions, PowerNow! aims to extend battery life while preserving responsive performance.
The technology was introduced in the mid-2000s with AMD’s mobile lines, including the Athlon XP-M and Turion
In operation, PowerNow! continuously monitors workload, temperature, and power conditions, selecting appropriate performance states to minimize
PowerNow! influenced later AMD energy-management approaches, contributing to the development of desktop and mobile power-saving features
