Energy-efficient processors are designed to perform computing tasks while consuming less power than traditional processors. This efficiency helps reduce electricity costs and minimizes heat generation, which can prolong the lifespan of devices. These processors are commonly used in mobile devices, laptops, and servers, where battery life and thermal management are crucial. Many energy-efficient processors utilize advanced technologies, such as multi-core architectures and dynamic voltage scaling, to optimize performance without wasting energy. Companies like Intel and AMD have developed specific lines of processors that focus on energy efficiency, catering to the growing demand for sustainable computing solutions.
