Intel Xeon Gold 6542Y

24C/48T · 4.1 GHz · 250 W

The Xeon Gold 6542Y is a 24-core, 48-thread 5th Gen Xeon Scalable (Emerald Rapids) processor for two-socket servers. The Y suffix denotes support for Intel Speed Select Technology - Performance Profile 2.0, so besides its default 24-core configuration at 250 W it can be switched to 20-core or 16-core profiles at lower power levels.

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.
