Server processor for heavy compute

This 28-core Xeon Gold 6258R runs at 2.70 GHz with 56 threads and 38.5 MB of L3 cache. It is built for multi-threaded server workloads such as virtualisation, database serving and high-performance computing. The six memory channels support large memory configurations typical of data-centre deployments. The processor is supplied new and includes the CPU only.

Suited to parallel workloads.

The high core count and thread density benefit applications that scale across many cores. Workloads that depend on maximum single-thread frequency or low core counts will not exploit this architecture. Buyers who need fewer cores or higher per-core clocks should consider a different model. Systems limited to fewer than six memory channels cannot use the full memory bandwidth.

28 cores and 56 threads define the scaling limit

The 28-core, 56-thread configuration sets the maximum parallelism available to the operating system and applications. This figure determines whether the processor can meet the concurrency demands of a given deployment. Match this core and thread count to the licensing and threading model of the target software before purchase.

Questions about this item

What comes in the box with the Xeon Gold 6258R and what must I buy separately?

The processor is sold as CPU only; a compatible heatsink and thermal compound must be sourced separately.

Which version of the Xeon Gold 6258R should I choose for a 28-core, 56-thread configuration?

This is the single 28-core, 56-thread model with part number SRGZF; there are no alternative core-count versions of this SKU.

What does the 2.70 GHz base clock mean for real-world server workloads?

All 28 cores run at a guaranteed 2.70 GHz base frequency, providing consistent throughput for heavily threaded server applications.
