Engineer's Note: The Intel Xeon Silver 4108 pairs 8 cores / 16 threads with a 1.80 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. 1.80 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.
2. 8 cores / 16 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — web serving and mid-tier application clusters — 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. 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.
4. Memory platform on the Intel Xeon Silver 4108: 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.
5. 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.
If your roadmap includes web serving and mid-tier application clusters, the Intel Xeon Silver 4108 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 workloads suit 8-core processors best?
A: With 8 cores / 16 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 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: Is the Intel Xeon Silver 4108 compatible with my server?
A: The Intel Xeon Silver 4108 uses the FCLGA3647 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: 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: 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.
