Key Features

Intel Xeon 5218B processor
16 cores, 32 threads
2.3 GHz base frequency
22 MB Intel Smart Cache
125 W thermal design power
DDR4 memory support

Drive more work through each server with the Intel Xeon 5218B processor for Cisco UCS environments. With 16 cores, a 2.3 GHz base frequency, and 22 MB of cache, this CPU is built for workloads that benefit from parallel execution and consistent throughput across many active sessions or services. The 125 W thermal design power reflects its higher-performance class, making it a strong fit for infrastructure teams that prioritize consolidation density and application responsiveness over minimal power draw. DDR4 memory support at 2,666 MHz helps keep data moving efficiently between memory and processor, which matters in virtualized hosts, analytics nodes, and multi-service application servers. Compared with lower-core processors, the 5218B gives you more scheduling headroom for mixed workloads and larger VM counts. For Cisco UCS deployments where compute capacity is the constraint, this processor helps extend server utility without changing the platform standard.

Ideal For

High-density virtualization hosts in Cisco UCS clusters
Database and analytics servers with parallel processing demand
Application consolidation nodes for enterprise workloads
