what is undervolting gpu

Undervolting a GPU is the process of reducing the voltage that the graphics processing unit (GPU) receives from the power supply. This aims to maintain performance relatively close to stock settings while boosting efficiency by reducing power draw and heat generation. Undervolting can be achieved using software such as MSI Afterburner or GPU Tweak, and it is considered relatively safe and free to do. The benefits of undervolting include improved energy efficiency, quieter operation, and reduced heat generation, while potential drawbacks may include changes to performance and the need for extensive testing to find the optimal settings. Undervolting a GPU does not necessarily affect its performance, and it can be a useful technique for achieving comparable clock speeds with less thermal stress and power consumption.
