Product highlights

Two complete execution cores in one processor package provide advancements in simultaneous computing such as multi-threaded applications and multi-tasking environments. Dual-core processing efficiently delivers performance while balancing power requirements

High-performance front-side bus (FSB) provides dual-processor support for demanding high-performance, volume applications. Combined with dual-core processing, this supports up to four simultaneous threads on the system

Enhanced Intel SpeedStep® technology allows a system to dynamically adjust processor voltage and core frequency, decreasing average power consumption and average heat production

Intel® Smart Cache Design allows two execution cores to share 2 MB of L2 cache, reducing FSB traffic and enhancing system responsiveness

Intel® Advanced Thermal Manager supports new digital temperature sensors and thermal monitors on each execution core to enhance thermal monitoring accuracy

Enhanced 36-bit memory addressing supports up to 16 GB of DDR2 memory, when paired with the Intel® E7520 chipset
