Engineer's Note: The Intel Xeon Silver 4109T Energy Efficient pairs 8 cores / 16 threads with a 2.00 GHz base clock that boosts to 3.00 GHz on demand and 11.00 MB of on-die cache, making it a drop-in candidate for web serving and mid-tier application clusters. Its FCLGA3647 socket means it slots into existing platforms without board redesign. Positioned as a cost-efficient tier aimed at dense, scale-out workloads, it is built for sustained multi-user workloads.
1. 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.
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. Memory platform on the Intel Xeon Silver 4109T Energy Efficient: support for DDR4-2400, up to 768 GB of RAM, 115.2 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. 2.00 GHz base / 3.00 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.
5. 11.00 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.
When you spec out web serving and mid-tier application clusters, the Intel Xeon Silver 4109T Energy Efficient turns architectural decisions into predictable outcomes. Its 8-core layout sizes the node for expected concurrency, the 3.00 GHz turbo headroom keeps interactive paths responsive, and 768 GB 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: What memory does it require?
A: The platform supports DDR4-2400. 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: 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: 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: 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.
