Intel Xeon Gold 5318H Processor | 18 Cores 36 Threads 2.5GHz to 3.8GHz | 24.75MB Cache 4-Socket Ready for Mission-Critical Enterprise Servers

Specifications

Engineer's Note

Engineer's Note: The Intel Xeon Gold 5318H pairs 18 cores / 36 threads with a 2.5 GHz base clock that boosts to 3.8 GHz on demand and 24.75 MB of on-die cache, making it a drop-in candidate for virtualization hosts running dozens of VMs. The 150 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. 24.75 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. 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.
3. 48 PCIe lanes (PCIe 3.0): 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.
4. 18 cores / 36 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — virtualization hosts running dozens of VMs — share the die without context-switch overhead. When you size licenses or plan VM placement, thread count is the number the scheduler actually sees.
5. 150 W TDP: the thermal envelope is sized for sustained all-core loads in multi-socket chassis, so the processor holds its rated clocks through long batch windows instead of throttling halfway through. It also keeps per-socket cooling and power costs predictable when you scale out — datacenter capacity planning runs on numbers like these.

Why These Specs Matter

For teams running virtualization hosts running dozens of VMs, the Intel Xeon Gold 5318H turns architectural decisions into predictable outcomes. Its 18-core layout sizes the node for expected concurrency, the 3.8 GHz turbo headroom keeps interactive paths responsive, and 1.12 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.
