HPE P67090-B21 Intel Xeon Silver 4509Y G11 Processor Kit
Overview
The HPE P67090-B21 is a genuine Intel Xeon Silver 4509Y processor kit engineered for HPE ProLiant G11 servers. Built on Intel's Sapphire Rapids architecture, this octa-core CPU runs at 2.6GHz base with 22.5MB of Intel Smart Cache and a 125W TDP — a sensible balance of compute density and power envelope for mid-range enterprise workloads. If you are expanding compute capacity on a ProLiant DL360, DL380, ML350, or related G11 platform, this is the HPE-native option that installs without compatibility guesswork. Sourced factory-new with a genuine HPE security sticker, the P67090-B21 ships as a Full Processor Option Kit including the processor and all required installation hardware.
Key Features
- Sapphire Rapids Architecture: Intel's Sapphire Rapids platform brings DDR5 memory support and PCIe Gen 5 I/O to the ProLiant G11 lineup — directly increasing memory bandwidth and NVMe storage throughput compared to prior-generation platforms. If your application is memory-sensitive (databases, VMs, video analytics), this matters.
- 8-Core / 64-bit Design at 2.6GHz: Eight physical cores at 2.6GHz gives you solid single-threaded performance alongside multi-threaded capacity — the right profile for mixed enterprise workloads where you need consistent core availability rather than a burst-heavy configuration.
- 22.5MB Intel Smart Cache: The large L3 cache reduces main-memory fetch frequency under sustained workloads. In practice, this stabilizes latency on database query patterns and analytics pipelines that would otherwise thrash slower memory tiers.
- 125W Thermal Design Power: At 125W TDP, this processor fits within the standard ProLiant G11 thermal envelope. You do not need upgraded cooling beyond what a properly configured G11 chassis already provides — simplifying deployment in existing rack environments.
- Socket FCLGA4677: The FCLGA4677 socket is exclusive to the Intel Scalable (4th Gen Xeon) platform. Verify your server board is G11 before ordering — this CPU is not backward-compatible with G10 or G10+ socket configurations.
- Full Processor Option Kit (P67651-001 included): The kit ships as a complete installation package. HPE bundles the necessary retention hardware, so the processor is ready to seat directly into a G11 motherboard without sourcing additional parts.
Integration & Compatibility
The P67090-B21 is validated for HPE ProLiant ML110 G11, ML350 G11, DL320 G11, DL360 G11, DL380 G11, and DL380a G11. Outside this list, do not assume socket compatibility — even within the ProLiant family, G10 and G10+ boards use a different socket and will not accept this CPU. For multi-processor configurations, confirm your server's maximum processor count before ordering a second unit.
What's in the Box

Frequently Asked Questions
Q: Which HPE ProLiant servers are compatible with the P67090-B21?
A: The P67090-B21 is validated for HPE ProLiant ML110 G11, ML350 G11, DL320 G11, DL360 G11, DL380 G11, and DL380a G11 platforms.
Q: Is the P67090-B21 compatible with G10 or G10+ ProLiant servers?
A: No. The P67090-B21 uses the FCLGA4677 socket, which is specific to the G11 (4th Gen Intel Xeon Scalable) platform. G10 and G10+ servers use different socket designs and are not compatible.
Q: What is included in the P67090-B21 kit?
A: The kit includes the Intel Xeon Silver 4509Y processor (HPE spare P67651-001) and the required installation retention hardware for ProLiant G11 platforms.
Q: What is the TDP of the Xeon Silver 4509Y, and does it require upgraded server cooling?
A: The processor has a 125W TDP, which falls within the standard thermal envelope of supported ProLiant G11 servers. No additional cooling upgrades are required for standard rack configurations.
Q: Is this a genuine HPE processor or a third-party substitute?
A: The P67090-B21 is a genuine HPE product and ships with a genuine HPE security sticker for verification. It is not a third-party or grey-market alternative.
The P67090-B21 lands in a practical slot of the G11 Xeon lineup — eight Sapphire Rapids cores at 2.6GHz with 22.5MB of Smart Cache and a 125W TDP. For teams running ProLiant DL360 or DL380 G11 nodes in a surveillance NVR or edge compute role, this is a processor you can deploy without thermal surprises or power budget recalculation.
Technical Highlights:
- 22.5MB Smart Cache: Reduces L3 miss penalties under sustained analytics or database read patterns — meaningful when the server is running simultaneous video decode or indexing workloads rather than bursty web traffic.
- FCLGA4677 Socket (Sapphire Rapids): Locks you into the G11 platform but unlocks DDR5 and PCIe Gen 5 — infrastructure that pays forward as NVMe and network card speeds continue increasing.
- 125W TDP: Fits the standard ProLiant G11 thermal solution without aftermarket cooling. For dense rack deployments, this keeps per-node power draw predictable across a full chassis.
Deployment Considerations:
- Confirm server generation before installing — FCLGA4677 is G11-only. A G10+ board will not accept this CPU physically or electrically.
- This is a single-processor kit. If your workload requires dual-socket capacity, verify the target server supports multi-processor configuration before sourcing a second P67090-B21.
Best fit for ProLiant G11 nodes serving as NVR backend compute, virtualization hosts, or edge analytics platforms where consistent 8-core throughput at a controlled 125W power envelope is the design target.
