48C/96T · 4.0 GHz · 350 W

The Xeon Platinum 8558P is a 48-core 5th Gen Xeon Scalable (Emerald Rapids) processor launched in December 2023. The P suffix marks a model tuned for cloud infrastructure-as-a-service hosts: compared with the Platinum 8558 it raises the base clock from 2.1 to 2.7 GHz and supports DDR5-5600 memory, at a higher 350 W TDP and with three UPI links instead of four.

Notes
Microsoft lists 5th Generation Xeon Scalable processors as supported for Windows 11 versions 24H2 and 25H2; Microsoft has not published a separate list for 26H2, so the 25H2 status is carried over. The Windows 10 22H2 list stops at 3rd Generation Xeon Scalable. Server deployments typically run Windows Server or enterprise Linux; Emerald Rapids is supported by mainstream Linux distributions.
