Engineer's Note: The Intel Xeon Gold 5218R pairs 20 cores / 40 threads with a 2.10 GHz base clock that boosts to 4.00 GHz on demand and 27.50 MB of on-die cache, making it a drop-in candidate for virtualization hosts running dozens of VMs. 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. 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.
2. 20 cores / 40 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.
3. Memory platform on the Intel Xeon Gold 5218R: support for DDR4-2933, up to 1 TB of RAM, 140.8 GB/s of peak bandwidth. This is the headroom in-memory databases and dense VM farms need — capacity for growth, bandwidth for the data streams in between.
4. 27.50 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.
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 virtualization hosts running dozens of VMs, the Intel Xeon Gold 5218R turns architectural decisions into predictable outcomes. Its 20-core layout sizes the node for expected concurrency, the 4.00 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: 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: What workloads suit 20-core processors best?
A: With 20 cores / 40 threads, this processor is sized for multi-threaded server workloads: virtualization hosts, database servers, and application consolidation. Single-threaded-light environments (file servers, internal tools) will leave headroom unused.
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.
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: 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.
