Clearwater Forest is the codename for Intel's Xeon 6+ server processors, launched on June 1, 2026 at Computex.
[1]
It is the first data center processor built on the Intel 18A process node.
Clearwater Forest uses exclusively Darkmont E-cores (efficiency cores), with up to 288 cores per socket, targeting cloud-native, networking, and scale-out workloads.
It succeeds Sierra Forest and shares I/O tiles with Granite Rapids.
All models support 2-socket configurations, 12 channels of DDR5-8000, 96 PCIe 5.0 lanes, 64 CXL 2.0 lanes, SGX, TDX, and built-in accelerators (QAT, DSA, DLB, IAA).
