Intel’s Nova Lake S Xeon chips appear in Dunlow platform leak with up to 28 cores

Intel appears to be preparing a return to mainstream desktop Xeon processors with a new platform called Dunlow. The platform has surfaced in shipping logs and is reportedly built around Nova Lake S CPUs, bringing support for the newer LGA 1954 socket and up to 28 cores in early listed configurations.

This would mark an important shift for Intel’s smaller workstation and entry server Xeon lineup. The company’s last mainstream desktop Xeon family, Xeon E 2400, was based on Raptor Lake and topped out at 8 cores. Intel later introduced Bartlett Lake S chips with up to 12 performance cores, but those parts were not part of the Xeon lineup and were aimed more at edge systems.

Nova Lake may change that by giving Intel a fresh desktop Xeon platform with a much higher core count and newer architecture. According to the shipping log details, the Dunlow platform supports Nova Lake S processors with up to 28 cores, a 95W TDP, and dual channel DDR5 memory.

Dunlow could bring E cores back to Intel’s mainstream Xeon lineup

One of the more interesting parts of the leak is the expected CPU layout. Intel’s previous mainstream Xeon chips often leaned on performance core only designs. The 28 core Nova Lake S Xeon model, however, is expected to use a mix of performance cores and efficiency cores. That would bring Intel’s hybrid architecture back into this class of Xeon processors.

The move makes sense if Intel wants to improve multi threaded performance while keeping power limits under control. A 28 core chip at 95W would need a careful balance between performance, efficiency, and workload behavior. For entry workstations, small business servers, and edge systems, that mix could offer more flexibility than older Xeon E processors.

The first Dunlow board has also reportedly appeared. The listing mentions a Supermicro MBD X15SDCB IN001 reference board or customer reference board with LGA 1954 and DDR5 support. That suggests Intel and its partners are already preparing platform validation.

The leak also points to Intel preparing more than one Nova Lake S product type. Alongside the mainstream Xeon effort, Intel is reportedly working on Nova Lake S chips for edge use, including models with up to 12 Xe3P integrated GPU cores. That suggests Nova Lake could cover a wide range of systems, from desktops to edge deployments and compact professional machines.

For Intel, bringing Xeon back to a stronger mainstream platform could help fill a gap. Not every business or workstation buyer needs a large Xeon server platform, but many still want ECC support, business grade boards, long lifecycle availability, and certified platform stability. A modern Nova Lake S Xeon family could serve that market better than the older Raptor Lake based Xeon E lineup.

The timeline is still unofficial. Nova Lake desktop processors are expected in early 2027, and the Xeon versions may follow a few months later. Since this information comes from shipping logs and early listings, specifications may still change before launch.

Still, the direction is clear. Intel appears to be preparing a more capable mainstream Xeon platform with more cores, a new socket, DDR5 support, and a return to hybrid CPU design. If the 28 core configuration holds, Dunlow could be Intel’s most meaningful update to entry Xeon systems in years.
