Intel Xeon Platinum 8280 Processor | 28 Cores 56 Threads up to 4.0GHz Turbo | For Mission-Critical Computing, Virtualization & HPC

Specifications

Engineer's Note

Engineer's Note: The Intel Xeon Platinum 8280 pairs 28 cores / 56 threads with a 2.7 GHz base clock that boosts to 4.0 GHz on demand and 38.5 MB of on-die cache, making it a drop-in candidate for large-scale virtualization hosts and in-memory databases. The 205 W thermal envelope keeps it inside standard server cooling budgets. 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.

Technical Specs & Insights

1. 28 cores / 56 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — large-scale virtualization hosts and in-memory databases — 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. 2.7 GHz base / 4.0 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. Memory platform on the Intel Xeon Platinum 8280: support for DDR4-2933, 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.
4. 48 PCIe lanes (PCIe 3.0): the lane budget drives expansion. NVMe SSDs, 25/100GbE NICs, and GPU accelerators each consume 8–16 lanes, and this processor keeps enough lanes free to build a storage-dense or GPU-accelerated node without a PCIe switch — saving cost and a hop of latency.
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.

Why These Specs Matter

When you spec out large-scale virtualization hosts and in-memory databases, the Intel Xeon Platinum 8280 turns architectural decisions into predictable outcomes. Its 28-core layout sizes the node for expected concurrency, the 4.0 GHz turbo headroom keeps interactive paths responsive, and the platform is built to grow with your workload. Every unit passes functional testing before shipment, and our bulk-pricing desk keeps multi-socket refresh projects inside budget.
