Engineer's Note: The Intel Xeon Platinum 8253 pairs 16 cores / 32 threads with a 2.20 GHz base clock that boosts to 3.00 GHz on demand and 22 MB of on-die cache, making it a drop-in candidate for HPC clusters and AI inference farms. Its FCLGA3647 socket means it slots into existing platforms without board redesign. 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.
1. 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.
2. 2.20 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.
3. 22 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. 16 cores / 32 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.
5. Memory platform on the Intel Xeon Platinum 8253: support for DDR4-2933, up to 1 TB of RAM, 6 memory channels, 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.
If your roadmap includes HPC clusters and AI inference farms, the Intel Xeon Platinum 8253 turns architectural decisions into predictable outcomes. Its 16-core layout sizes the node for expected concurrency, the 3.00 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: 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: What workloads suit 16-core processors best?
A: With 16 cores / 32 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: 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 memory does it require?
A: The platform supports DDR4-2933. 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 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.
