Server-Grade Xeon Processor for Heavy Multitasking

This Intel Xeon Platinum 8558P delivers 48 cores and 96 threads for demanding server workloads. A base frequency of 2.70 GHz scales to a 4 GHz max turbo under load. The FCLGA4677 socket targets dual-socket platforms built for virtualisation, database or compute clusters. Buyers needing a single-socket workstation chip or consumer desktop performance should look elsewhere.

Sustained Load Behaviour with High Core Count

All 48 cores maintain the 2.70 GHz base clock during prolonged multi-threaded tasks thanks to the Emerald Rapids architecture. The 4 GHz turbo engages on fewer active cores when thermal headroom allows. Without a bundled cooler, sustained throughput depends entirely on the system integrator’s thermal solution. Workloads that idle frequently will not benefit from the high core density.

Installation Notes for FCLGA4677 Platform

The package contains the CPU only; no heatsink, thermal paste or mounting hardware is supplied. Clean-pull condition means minor cosmetic marks exist but the part tests to OEM specifications with no missing capacitors or substrate damage. Installers must provide a compatible LGA4677 cooler and apply fresh thermal interface material. Builders without server-board experience or access to a qualified thermal solution should not attempt this upgrade.

Questions about this item

How much heat does the Xeon 8558P generate under sustained load?

The processor has a base frequency of 2.70 GHz and a max turbo of 4 GHz with 48 cores and 96 threads, so sustained workloads will draw significant power and require robust server-grade cooling.

What motherboard socket is required for the SRN52?

The CPU uses the FCLGA4677 socket, so you need a compatible server motherboard with that exact socket and appropriate chipset support.

Will the 8558P work in a dual-socket board alongside an older Xeon Scalable processor?

No, the Emerald Rapids architecture requires matching generation CPUs in a dual-socket configuration; mixing with previous Xeon Scalable models is not supported.
