Intel Xeon Gold 5318S Processor | 24 Cores 48 Threads 2.1GHz-3.4GHz | 36MB Cache 165W TDP for Mainstream Enterprise Servers & Data Centers

Specifications

Engineer's Note

Engineer's Note: The Intel Xeon Gold 5318S pairs 24 cores / 48 threads with a 2.10 GHz base clock that boosts to 3.40 GHz on demand and 36 MB of on-die cache, making it a drop-in candidate for relational databases (SQL Server, PostgreSQL) and ERP systems. The 165 W thermal envelope keeps it inside standard server cooling budgets. Its FCLGA4189 socket means it slots into existing platforms without board redesign. Positioned as the workhorse tier of the Scalable family, balancing per-core speed and core density, it is built for sustained multi-user workloads.

Technical Specs & Insights

1. 36 MB of shared cache: a large last-level cache keeps hot working sets on-die, cutting memory round-trips for databases and compilers. Fewer main-memory accesses translate directly into lower average latency and better tail performance under load — often the difference you feel before any benchmark confirms it.
2. 24 cores / 48 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — relational databases (SQL Server, PostgreSQL) and ERP systems — share the die without context-switch overhead. When you size licenses or plan VM placement, thread count is the number the scheduler actually sees.
3. FCLGA4189 platform compatibility: matching sockets across your fleet simplifies spares management — one processor SKU covers many chassis generations, and upgrades become a socket swap rather than a board replacement. That matters at 3 a.m. when a node needs to be back in service before morning.
4. Scalability to 2-socket systems: in multi-socket servers the processors share memory over a coherent interconnect (11.2 GT/s), letting a single OS instance use all cores and all RAM — the classic architecture for large relational databases and consolidation hosts.
5. 64 PCIe lanes (PCIe 4.0): the lane budget drives expansion. NVMe SSDs, 25/100GbE NICs, and GPU accelerators each consume 8–16 lanes, and this processor keeps enough lanes free to build a storage-dense or GPU-accelerated node without a PCIe switch — saving cost and a hop of latency.

Why These Specs Matter

When you spec out relational databases (SQL Server, PostgreSQL) and ERP systems, the Intel Xeon Gold 5318S turns architectural decisions into predictable outcomes. Its 24-core layout sizes the node for expected concurrency, the 3.40 GHz turbo headroom keeps interactive paths responsive, and 6 TB of addressable memory gives the platform room to grow. Every unit passes functional testing before shipment, and our bulk-pricing desk keeps multi-socket refresh projects inside budget.
