INTEL Xeon 4509Y 2.10GHz CPU
The Intel Xeon Silver 4509Y is an 8-core, 16-thread server processor from Intel’s 5th Gen Xeon Scalable family (Sapphire Rapids), positioned for entry-level and mid-range enterprise workloads such as virtualization hosts, file and storage servers, and general-purpose compute nodes. It suits system integrators and datacenter buyers balancing cost against modern platform features like DDR5 and PCIe Gen 5. Note that the socketed FCLGA 4677 package requires a compatible Sapphire Rapids/Emerald Rapids platform motherboard, so verify platform support before ordering.
Key specifications (table)
| Parameter | Specification |
| Product Name / SKU | Intel Xeon Silver 4509Y |
| Code Name / Architecture | 5th Gen Xeon Scalable (“Sapphire Rapids”) |
| Cores / Threads | 8 cores / 16 threads |
| Base Clock | 2.60 GHz |
| Max Turbo Frequency | Up to 4.10 GHz |
| L3 Cache | 22.5 MB |
| Thermal Design Power (TDP) | 125 W (verify server cooling and power provisioning) |
| Fabrication Process | Intel 7 (10 nm) |
| Memory Support | 8-channel DDR5, up to 4400 MT/s (memory speed is platform dependent) |
| Maximum Memory Capacity | Up to 4 TB (platform dependent) |
| UPI (Interconnect) | 2 × 16 GT/s (supports multi-socket systems) |
| PCIe Support | PCIe Gen 5, up to 80 lanes (per TechPowerUp) |
| Package / Socket | FCLGA 4677 |
Good to know
- Compatibility: The FCLGA 4677 socket is shared across Sapphire Rapids and Emerald Rapids platforms, but BIOS/firmware support and 4400 MT/s memory operation depend on the specific motherboard; confirm your board’s QVL before deployment.
- Family positioning: Within the Xeon Silver tier, the 4509Y offers 8 cores with dual UPI links and full 8-channel DDR5, making it a step up from earlier Silver generations for multi-socket or memory-bandwidth-sensitive workloads while sitting below Gold-class core counts.
- Buying tip: Confirm your workload’s core-count and memory-channel requirements against the 8-core/8-channel configuration—these CPUs are often purchased in matched pairs for 2-socket systems, so check stepping/lot consistency for multi-socket builds.
