Intel Xeon Platinum 8180 Processor - 28 Cores, 56 Threads, 2.5GHz Base, 3.8GHz Turbo, 38.5MB Cache, Flagship Platinum Server CPU (P/N: CD8067303560000)

Specifications

Engineer's Note

Engineer's Note: The Intel Xeon Platinum 8180 Flagship pairs 28 cores / 56 threads with a 2.5 GHz base clock that boosts to 3.8 GHz on demand and 38.5 MB of on-die cache, making it a drop-in candidate for HPC clusters and AI inference farms. Positioned as the top tier of Intel's Scalable lineup, built for maximum throughput and platform reliability, it is built for sustained multi-user workloads.

Technical Specs & Insights

1. 28 cores / 56 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — HPC clusters and AI inference farms — share the die without context-switch overhead. When you size licenses or plan VM placement, thread count is the number the scheduler actually sees.
2. Memory platform on the Intel Xeon Platinum 8180 Flagship: support for DDR4-2666, up to 768 GB of RAM, 6 memory channels. This is the headroom in-memory databases and dense VM farms need — capacity for growth, bandwidth for the data streams in between.
3. Scalability to 8-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.
4. 38.5 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. 2.5 GHz base / 3.8 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.

Why These Specs Matter

For teams running HPC clusters and AI inference farms, the Intel Xeon Platinum 8180 Flagship turns architectural decisions into predictable outcomes. Its 28-core layout sizes the node for expected concurrency, the 3.8 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.
