Engineer's Note: The Intel Xeon Gold 5220S pairs 18 cores / 36 threads with a 2.70 GHz base clock that boosts to 3.90 GHz on demand and 24.75 MB of on-die cache, making it a drop-in candidate for relational databases (SQL Server, PostgreSQL) and ERP systems. Its FCLGA3647 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. 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. Scalability to 2-socket systems: in multi-socket servers the processors share memory over a coherent interconnect (10.4 GT/s UPI), letting a single OS instance use all cores and all RAM — the classic architecture for large relational databases and consolidation hosts.
3. 2.70 GHz base / 3.90 GHz turbo: the frequency governor drops light threads onto boosted cores, so single-threaded paths (license checks, stored procedures, log processing) finish fast while background jobs keep the remaining cores saturated. The result is responsive interactive performance without sacrificing aggregate throughput.
4. Memory platform on the Intel Xeon Gold 5220S: support for DDR4-2666, up to 1 TB of RAM. This is the headroom in-memory databases and dense VM farms need — capacity for growth, bandwidth for the data streams in between.
5. FCLGA3647 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.
When you spec out relational databases (SQL Server, PostgreSQL) and ERP systems, the Intel Xeon Gold 5220S turns architectural decisions into predictable outcomes. Its 18-core layout sizes the node for expected concurrency, the 3.90 GHz turbo headroom keeps interactive paths responsive, and 1 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: 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: Do you offer bulk pricing for fleet upgrades?
A: Yes. Multi-socket refresh projects and fleet orders get consolidated pricing — request a quote through the form on this page with your target quantity, and our team responds with an offer typically within one business day.
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 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.
Q: What is the thermal design power?
A: The TDP is listed in the specifications table. It stays within standard server cooling envelopes for the platform generation.
