Robust multitasking capabilities ensure that a computing platform featuring the dual-core Intel Core 2 Duo processor won't slow down, even when running multiple software applications simultaneously.Intel® Core™2 Duo Processor Product HighlightCombining Intel's highly efficient 45nm manufacturing technology and Intel® Core™ microarchitecture, the Intel Core 2 Duo processor delivers robust performance for both home and business software applications. With two complete computing "brains" on one physical processor, this dual-core processor delivers more performance with greater energy efficiency than older single-core processors. For PC users, this means doing more simultaneously with less slowdown and hesitation. Intel Technology45nm Hafnium-Based Architecture. Thanks to a naturally occurring element called Hafnium, Intel engineers were able to shrink the size of new Intel processors and pack more computing technology into less space. The result is improved performance with less energy wastage.Intel® Wide Dynamic Execution. Enables the delivery of more instructions per clock cycle for shorter execution times and improved energy efficiency—accomplish more simultaneously and with greater efficiency.Intel® Intelligent Power Capability. Turning off portions of the processor when they aren't being used improves overall energy efficiency and reduces heat production, resulting in a quieter, more energy efficient system.Intel® Smart Memory Access. Increasing available data bandwidth means more multitasking with less slowdown—run more demanding applications simultaneously and accomplish more in less time.Intel® Advanced Smart Cache. Placing data closer to the processing cores improves platform responsiveness and performance with a wide range of applications.Intel® Advanced Digital Media Boost. Accelerates performance with a wide range of applications, including video, gaming, speech and image, photo processing, encryption, financial, engineering and scientific applications.Intel® HD Boost. Available only on the latest 45nm Intel processors, this revolutionary technology takes Intel® Advanced Digital Media Boost and improves it even further, enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution will see additional performance improvementsPerformance for MultitaskingWith two powerful and highly efficient processing cores, the Intel Core 2 Duo processor frees you to run multiple software applications at the same time without compromising performance or responsiveness. Everything including email, downloading, online shopping, and video editing can be done simultaneously and with greater efficiency. No longer is it necessary to choose between work and play.Energy EfficiencyWhen working or playing hard, you want to keep distractions to a minimum. Thanks to Intel's exclusive 45nm technology, the Intel Core 2 Duo processor runs very efficiently—consuming less energy and producing less heat then previous-generation processors. Since desktop PCs featuring the Intel Core 2 Duo processor run cooler, they require less cooling, meaning fewer fans and a quieter computing experience. And with energy-saving features that shut down portions of the processor when they are not in use, the Intel Core 2 Duo processor is easier on your energy bill and the environment.
