The LENOVO 49Y3689 is powered by the Intel Xeon E5520, a quad-core processor designed to deliver balanced performance and energy efficiency for demanding server and workstation environments. Operating at a speed of 2.26GHz, this processor is capable of handling multiple tasks simultaneously thanks to Intel Hyper-Threading Technology, which allows each core to process two threads concurrently. With a thermal design power (TDP) of 80 watts, it strikes an optimal balance between performance and power consumption. The E5520 supports Triple Channel DDR3 memory up to 800/1066/1333 MHz, allowing for faster data processing and efficient handling of memory-intensive applications. It also features an 8 MB SmartCache, which improves processing efficiency by reducing the time needed to access frequently used data and instructions. Integrated Intel Virtualization Technology (VT-x) enhances the system's ability to run multiple virtual environments, providing flexibility and maximizing server utilization. The LENOVO 49Y3689 processor model E5520 is engineered to boost productivity, offer substantial scalability, and ensure robust reliability for a wide range of server and workstation applications.
