Intel Xeon Gold 6258R 28-Core Server Processor LGA 3647 Cascade Lake-SP

It needs Socket LGA 3647 and a board that supports Cascade Lake-SP. Socket is absolute (a processor for another socket will not fit whatever else matches), and the board also needs a BIOS level that recognises this stepping. Send us the server or board model and we will confirm both before you order.

It is a 205W part, so the chassis has to be rated for that at the ambient temperature you run. Dropping a 205W processor into a chassis specified for a lower-wattage bin will throttle under sustained load rather than fail outright, which is harder to diagnose. Tell us the platform and we will check the thermal rating and whether a different heatsink is required.

28C / 56T. Per-core licensing on databases and some hypervisors means the core count is a cost decision as much as a performance one: a higher-clocked part with fewer cores is often cheaper to run overall. Tell us what you are licensing and we will quote both ways.

Yes. We supply through authorized distribution only, so the part carries the full Intel manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
