HPE INT Xeon-g 5416S CPU for HPE - P49653-B21

HPE P49653-B21 Intel Xeon Gold 5416S Processor Option Kit

Overview

The HPE P49653-B21 is an Intel Xeon Gold 5416S processor option kit sourced through HPE's channel for installation into compatible HPE ProLiant and Synergy server platforms. If you are expanding compute capacity on an existing HPE server deployment or configuring a new node for workloads that demand scalable multi-core processing, the P49653-B21 (often searched as P49653 B21) is the HPE-validated path to adding Xeon Gold 5416S performance to your infrastructure.

This is a factory-new, genuine HPE processor kit — not a grey-market or parallel-import component. Sourcing HPE processor options through the HPE channel ensures firmware compatibility, HPE Integrated Lights-Out (iLO) recognition, and full support eligibility with HPE support contracts. A third-party or grey-market CPU may physically fit but will frequently trigger iLO warnings, disable HPE's advanced server management features, or be excluded from warranty coverage on the host system.

Key Features

• Intel Xeon Gold 5416S Architecture: The 5416S belongs to Intel's 4th Gen Xeon Scalable (Sapphire Rapids) family — a generation that introduced on-package HBM-capable variants, AMX (Advanced Matrix Extensions) for AI inference, and significantly improved per-core memory bandwidth over prior generations. For HPE server deployments running virtualization-heavy, data analytics, or mixed enterprise workloads, the architectural improvements in Sapphire Rapids translate to fewer cores doing more work per clock cycle.
• HPE-Validated Component: HPE processor option kits are tested and validated against HPE's server firmware stack. This matters in practice: iLO health monitoring, SPP (Service Pack for ProLiant) firmware updates, and HPE OneView inventory management all depend on recognized, validated hardware. An unrecognized CPU can silently degrade manageability even when the server POST succeeds.
• Factory-New Genuine Part: Packaged and sourced as a new unit — not refurbished, not pulled from a decommissioned system. For servers in production or under SLA, this eliminates questions about prior thermal cycling, pin condition, or IHS integrity that arise with used processors.
• Package Dimensions — 10.00 × 8.80 × 2.70 in, 0.84 lb: The kit ships in HPE's standard processor option packaging. The weight of 0.84 lb reflects the retail box assembly including protective tray and documentation insert — not the bare die weight. Plan for standard ESD-safe handling procedures during installation; processor option kits should not be stored outside their anti-static packaging until the moment of installation.
• Sourced from Malaysia (Country of Origin: MY): HPE's Xeon option kits in this family are assembled and packaged at HPE's Malaysia manufacturing operations, consistent with HPE's broader ProLiant accessory supply chain. Country-of-origin documentation is available for procurement teams with TAA or supply-chain transparency requirements — confirm TAA compliance status with your procurement contact for this specific SKU if it is a hard requirement.
• UNSPSC 43201503 — Microprocessors: The UNSPSC code confirms classification as a microprocessor component, relevant for procurement systems that auto-categorize by UNSPSC for budget coding, contract compliance, or punch-out catalog alignment.

Integration and Compatibility

The P49653-B21 is designed for installation into HPE server platforms that support Intel Xeon Gold 5400-series processors. Compatible platforms typically include HPE ProLiant DL and ML series servers and HPE Synergy compute modules configured for 4th Gen Intel Xeon Scalable support. Before ordering, verify compatibility against the HPE QuickSpecs document for your specific server model — HPE publishes per-platform processor support matrices that confirm TDP headroom, memory channel support, and BIOS version requirements. Installing a processor option kit without confirming platform compatibility is the single most common cause of failed upgrades in the field.

For multi-socket configurations, order matching processor kits to ensure symmetric NUMA topology — asymmetric Xeon Gold populations in a dual-socket system can produce unpredictable memory latency characteristics under NUMA-aware workloads.

Frequently Asked Questions

Q: What servers is the HPE P49653-B21 compatible with?

A: The P49653-B21 is designed for HPE server platforms supporting 4th Gen Intel Xeon Scalable (Sapphire Rapids) processors. Confirm exact compatibility using the HPE QuickSpecs for your specific server model before ordering.

Q: Is this a factory-new processor or a refurbished unit?

A: The P49653-B21 is a factory-new, genuine HPE processor option kit — not refurbished or pulled from a prior system.

Q: Why does sourcing matter for HPE processor option kits?

A: HPE-validated processor kits are recognized by iLO and HPE management software. Grey-market or non-validated CPUs can trigger iLO alerts, disable server management features, or affect HPE support eligibility on the host platform.

Q: What is the country of origin for the P49653-B21?

A: The P49653-B21 is manufactured in Malaysia (MY), consistent with HPE's ProLiant accessory supply chain.

Q: What does the UNSPSC code 43201503 mean for procurement?

A: UNSPSC 43201503 classifies this product as a microprocessor — useful for procurement systems that use UNSPSC codes for budget categorization, contract compliance, or punch-out catalog alignment.

The HPE P49653-B21 is a processor option kit, and the most important thing I tell integrators about HPE CPU upgrades is this: the physical install is the easy part. The hard part is pre-validating platform compatibility against the HPE QuickSpecs before the kit ships to site — especially in dual-socket configurations where NUMA topology mismatches can degrade application performance in ways that don't show up until the workload runs under load.

Technical Highlights:

• Package weight 0.84 lb / 10.00 × 8.80 × 2.70 in: Standard HPE processor option box format — includes protective ESD tray. Don't open the anti-static bag until you're at the socket; even brief exposure in a dry server room is a risk for a component at this price point.
• Xeon Gold 5416S (Sapphire Rapids): 4th Gen Xeon Scalable introduces AMX instructions relevant to AI inference workloads and improved per-core memory bandwidth — meaningful if you're running virtualization density or analytics on the host platform.
• HPE channel-sourced, factory-new: iLO recognition and SPP firmware update compatibility depend on validated components. A non-HPE CPU may POST but will frequently generate iLO health warnings and can complicate support case escalations.

Deployment Considerations:

• Always cross-reference the P49653-B21 against the HPE QuickSpecs for your exact server model and BIOS revision before ordering — processor support matrices change between BIOS versions, and a kit that fits physically may not be enabled until a firmware update is applied.
• In dual-socket deployments, both processor sockets should be populated with matching option kits to maintain symmetric NUMA topology; mixing processor generations or stepping levels is unsupported and can produce latency anomalies under production workloads.

This kit fits squarely in HPE ProLiant refresh and capacity-expansion scenarios where the host platform is already deployed and the goal is adding validated compute without disrupting the existing iLO/OneView management stack.
