The Intel Core 2 Duo processors are built in several of the world's most advanced, high-volume output manufacturing facilities using Intel's leading silicon process technology. The processor family is based on the revolutionary Intel Core microarchitecture, designed to provide powerful yet energy-efficient performance. With the power of dual cores, or computing engines, the processors can manage numerous tasks faster. They also can operate more smoothly when multiple applications are running, such as writing e-mails while downloading music or videos and conducting a virus scan.a virus scan.ecture, the Intel Core 2 Duo desktop processor delivers revolutionary dual-core performance and breakthrough processor energy efficiency. With Intel Wide Dynamic Execution, Intel Smart Memory Access, Intel Advanced Smart Cache and Intel Digital Media Boost, this new processor is designed to do more in less time. Additional features to support enhanced security, virtualization, and 64-bit computing make the Intel Core 2 Duo the most impressive new processor developed for an increasingly multimedia-centered, high-definition world.Design changes in the Intel Core 2 Duo processors that improve performance also increase processor energy efficiency by operating at lower frequencies that require less power to run. Intel Intelligent Power Capability optimizes energy usage of the processor cores by turning on computing functions only when needed. This more energy-efficient processor supports smaller, more capable, and quieter desktop PC to conserve critical power resources.
