Optimizing GPU Power with DVFS and AVFS Techniques

Описание: Optimizing GPU power consumption is crucial for enhancing energy efficiency, especially in high-performance computing and AI applications. Two key techniques used for this purpose are Dynamic Voltage and Frequency Scaling (DVFS) and Adaptive Voltage and Frequency Scaling (AVFS).
DVFS adjusts the voltage and frequency of the GPU dynamically based on the workload demands. By lowering the voltage and frequency during less intensive tasks, DVFS can significantly reduce power consumption while maintaining performance1.
AVFS goes a step further by adapting the voltage and frequency settings in real-time, considering variations in workload and environmental conditions. This technique helps in achieving even finer power optimization by responding to instantaneous changes in performance requirements2.
Together, these techniques help in balancing performance and power efficiency, making GPUs more suitable for energy-sensitive applications
