As a result, demanding users can accomplish more in less time.Intel® Core™2 Quad Processor Product HighlightStarting with Intel's revolutionary new high-efficiency, high-performance 45nm processor technology, Intel engineers decided to go one step farther in the performance department. By including up to 12 MB of shared L2 cache and Front Side Bus speeds of up to 1333 MHz, the Intel® Core™2 Quad processor pushes the technological innovation envelope farther than ever before. For users, this means the latest and most advanced software applications can open and run faster than ever before with superior responsiveness. When used with the latest multimedia software and next-generation games, dropped frames, long waiting times and stuttering performance are history. 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 improvementsMultimediaWith professional-grade photo, music and HD video editing software readily available for consumers, it's becoming increasingly popular to create, edit, and share entertainment with friends and family. Unfortunately, these same applications are notoriously resource hungry. Built to handle the most demanding software, the four cores of the 45nm Intel Core 2 Quad processor help ensure that when you're working with high-resolution photos, exporting your next audio mashup, or editing HD-quality home movies, your computing platform will be able to keep pace with your creative muse.MultitaskingA computing platform featuring a new 45nm Intel Core 2 Quad-Core processor maximizes processing efficiency, allowing computer users to juggle multiple projects in multiple applications without experiencing the slowdown typically seen with traditional single-core processors.GamingNext-generation gaming is more than just pretty environments and smooth motion. Behind the incredible visual realism of waterfalls or the unlucky ricochet of a bullet are intense, high-speed calculations of asset streaming, terrain generation, 3D rendering, and physics effects. When running select next-generation games, each of the cores in the Intel Core 2 Quad processor can be dedicated to each of these individual processes, resulting in smoother, more lifelike graphics and further blurring the line between virtual and reality.Product DescriptionIntel Core 2 Quad Processor Q9550 2.83GHz 1333MHz 12MB LGA775 EM64T CP
