The Intel Core 2 Quad processor is the latest in cutting edge processor technology for the desktop PC. Based on the Intel Core micro-architecture, the Intel Core 2 Quad processor delivers four complete execution cores within a single processor, delivering unprecedented performance and responsiveness. More instructions can be carried out per clock cycle, shorter and wider pipelines execute commands more quickly, and improved bus lanes move data throughout the system faster. Four dedicated, physical threads help operating systems and applications deliver additional performance, so you can experience better multi-tasking and multi-threaded performance across many types of applications and workload. A 4-pin connector is included for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance.
