HPE Xeon Gold 5416S 16-core server processor

The HPE P49653-B21 is a 16-core Xeon Gold 5416S processor designed for HPE server platforms. It delivers 32 threads at a 2 GHz base frequency with a 4 GHz maximum turbo speed. The 10 nm chip fits the LGA-4677 socket and includes 30 MB L3 cache plus 32 MB L2 cache. This component targets IT teams refreshing compute density in rack or tower servers.

150 W TDP with 30 MB L3 and 32 MB L2 cache

The 150 W thermal design power allows sustained multi-threaded throughput for virtualisation, database and container workloads. The combined 62 MB of on-chip cache reduces memory latency for working sets that fit inside the last-level cache. Workloads with larger active data or higher single-thread demand will reach the cache and frequency limits of this part.

Upgrade path from older Xeon Gold CPUs in LGA-4677

This processor replaces earlier Xeon Gold models that share the same socket and platform infrastructure. The jump is worthwhile when the additional cores, larger caches and higher turbo frequency translate into measurable throughput gains for licensed software or consolidated VMs. It is not suited for platforms requiring a different socket or for workloads that need integrated graphics acceleration.

Questions about this item

Will the 150 W Xeon Gold 5416S fit in the same LGA-4677 socket as my existing Xeon 5000 series CPUs?

Yes, the 5416S uses the LGA-4677 socket shared by the Xeon 5000 series, so it installs in the same socket without a board change.

How can I confirm the processor is running at its 4 GHz overclocking speed after installation?

Monitor the core frequencies in the server BIOS or an OS utility; all 16 cores should reach 4 GHz under load when thermal headroom allows.

Does the box include a heatsink or thermal paste, or must I order them separately?

The processor ships without a heatsink or thermal paste; both must be sourced separately for your server chassis.
