HPE P49653-B21 Intel Xeon Gold 5416S Processor Kit
Overview
The HPE P49653-B21 is an enterprise-grade processor upgrade kit featuring the Intel Xeon Gold 5416S CPU, designed specifically for HPE ProLiant Gen11 servers. This component is engineered for demanding data center environments where a strategic balance of multi-core performance and energy efficiency is critical. It directly addresses the need for robust compute power to handle concurrent virtualized workloads, complex database queries, and high-transaction applications without overprovisioning. At its core, this processor leverages Intel’s 4th generation Xeon Scalable architecture to deliver significant performance gains. With 16 cores and 32 threads, it provides substantial parallel processing capability. This is complemented by support for an advanced 8-channel DDR5 memory architecture, which increases memory bandwidth and responsiveness for data-intensive tasks. Integrated accelerators, including Intel Deep Learning Boost, provide hardware-level optimization for artificial intelligence and machine learning workloads, reducing latency for real-time analytics. Designed for seamless integration, the P49653-B21 processor fits the FCLGA4677 socket in compatible HPE ProLiant rack servers. Deployment allows IT teams to scale compute resources within their existing infrastructure, optimizing total cost of ownership. The processor’s thermal design power of 150W ensures it operates efficiently within the server’s existing cooling envelope, simplifying management and maintaining data center power and thermal stability.
