The Core 2 Duo is a line of dual-core processors developed by Intel. Launched in 2006, these CPUs were designed for desktop and laptop computers, offering improved performance and energy efficiency compared to previous single-core processors. The architecture allows for better multitasking, enabling users to run multiple applications simultaneously without significant slowdowns. Core 2 Duo processors are built on the 65nm and later 45nm manufacturing processes, which contribute to their lower power consumption. They support various technologies, including Intel 64 and Enhanced Intel SpeedStep, enhancing their capabilities for both everyday tasks and more demanding applications.
