Intel Xeon Gold 6338T Processor | 24 Cores 48 Threads 2.1GHz-3.4GHz | 36MB Cache 165W Power-Efficient for Mainstream Enterprise Servers

Specifications

Engineer's Note

Engineer's Note: The Intel Xeon Gold 6338T 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 latency-sensitive business applications. 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. 165 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.
2. 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.
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. 24 cores / 48 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — latency-sensitive business applications — share the die without context-switch overhead. When you size licenses or plan VM placement, thread count is the number the scheduler actually sees.

Why These Specs Matter

If your roadmap includes latency-sensitive business applications, the Intel Xeon Gold 6338T 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.
