Intel Xeon Platinum 8558P 48-core 2.70 GHz server processor PK8072205511500

SKU CH-Q8ME-KGHBE MPN PK8072205511500

A 48-core Xeon server processor running at 2.70 GHz with 260 MB L3 cache, 96 threads, a 4 GHz turbo frequency and a 350 W TDP for Socket LGA-4677

  • 48 cores power parallel server workloads
  • 96 threads maximise multi-threaded throughput
  • 260 MB L3 cache accelerates data access
  • 70 GHz base clock ensures steady performance
  • Socket LGA-4677 enables platform integration

Server CPU for multi-threaded workloads

The Intel Xeon Platinum 8558P is a 48-core server processor built for dense compute tasks. Its 96 threads and 260 MB L3 cache suit virtualisation hosts, database nodes and high-throughput batch jobs. Buyers needing fewer cores or lower power draw should look elsewhere.

Installation notes for LGA-4677

The processor fits the LGA-4677 socket and carries a 350 W thermal design power. A server-grade cooler rated for that heat load and a compatible power-delivery subsystem are required. Misaligned seating or insufficient cooling will cause immediate throttling or shutdown.

Platform limits of the LGA-4677 interface

The socket supports 64-bit processing and a maximum turbo frequency of 4 GHz. Memory channel count, PCIe lane allocation and RAS features depend on the chosen platform firmware. Workloads that exceed the 350 W envelope or require specialised accelerators cannot be addressed by this processor alone.

Questions about this item

How can I verify the 48-core Xeon 8558P is running at its 2.70 GHz base clock after installation?

Check the processor frequency in the server BIOS or use a hardware monitoring utility; it should report 2.70 GHz on all 48 cores under load.

What comes in the box with the PK8072205511500 tray processor and what must be sourced separately?

The tray processor arrives without a heatsink or fan; you must provide a LGA-4677 socket motherboard and a cooler rated for 350 W TDP.

Which version of the Xeon Platinum 8558P should I choose for a 96-thread workload needing large cache?

This single SKU delivers 48 cores, 96 threads and 260 MB L3 cache; there are no alternative capacities or cache sizes for the 8558P.
