Lenovo 4XG7A85277 – Intel Xeon Silver 4416+ Processor with Heat Sink

Overview :

The Lenovo 4XG7A85277 is a processor upgrade kit featuring the 4th Generation Intel Xeon Scalable Silver 4416+ CPU. Engineered for enterprise-class ThinkSystem servers, this 20-core processor is optimized for medium-density virtualization, mid-range database management, and high-efficiency data center workloads.

Operating at a base frequency of 2.0GHz with the ability to scale via Intel Turbo Boost technology, the 4416+ provides a significant increase in core count and multi-threaded performance over previous Silver-tier generations. It supports high-speed DDR5 memory and PCIe 5.0, facilitating rapid data throughput for I/O-intensive applications. The inclusion of Intel Advanced Matrix Extensions (AMX) enhances AI inference and training capabilities directly at the hardware level.

This kit is a field-integrated upgrade (FIU) designed specifically for compatible Lenovo ThinkSystem rack and tower servers. It includes the necessary thermal solution (heat sink) to maintain stable operation within a 165W TDP envelope. It is not intended for consumer-grade motherboards and requires a compatible LGA-4677 socket infrastructure.

Key Features :

• 20 physical cores and 40 threads manage complex parallel workloads

• 37.5MB L3 Cache reduces latency for data-intensive server applications

• Intel AMX acceleration improves performance for AI and deep learning

• DDR5-4000 memory support provides massive bandwidth for virtualization

• Integrated PCIe 5.0 support enables high-speed networking and storage
