Engineer's Note: The Intel Xeon Gold 6338 pairs 32 cores / 64 threads with a 2.00 GHz base clock that boosts to 3.20 GHz on demand and 48 MB of on-die cache, making it a drop-in candidate for latency-sensitive business applications. The 205 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.
1. 48 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. Scalability to 2-socket systems: in multi-socket servers the processors share memory over a coherent interconnect, letting a single OS instance use all cores and all RAM — the classic architecture for large relational databases and consolidation hosts.
3. 205 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.
4. 32 cores / 64 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.
5. 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.
If your roadmap includes latency-sensitive business applications, the Intel Xeon Gold 6338 turns architectural decisions into predictable outcomes. Its 32-core layout sizes the node for expected concurrency, the 3.20 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.
Q: Can I mix this processor with different models in the same server?
A: In multi-socket servers, matched processors (same model, same stepping) are strongly recommended. Mixed models can cause boot failures or instability because memory controllers and QPI/UPI links negotiate to the lowest common configuration.
Q: Is the Intel Xeon Gold 6338 compatible with my server?
A: The Intel Xeon Gold 6338 uses the FCLGA4189 socket. Check your motherboard's qualified processor list — any chassis with that socket and matching BIOS support will run it. Our team can confirm compatibility if you share your server model.
Q: What memory does it require?
A: The platform supports DDR4-3200. Use ECC registered memory (RDIMM/LRDIMM) — desktop UDIMMs are not compatible with Xeon sockets. Faster modules will downclock to the processor's rated speed.
Q: Does this CPU include a cooler?
A: Server processors are typically installed with chassis-specific heat sinks, so none is included. Match the heat sink to your server model for correct airflow direction — our team can advise on the right part.
Q: Is it new or refurbished? What warranty applies?
A: We offer both new and tested refurbished units — the condition is shown on each listing. All processors include a one-year warranty and pass functional testing (boot, memory controller, all cores) before dispatch.
