Intel just made its most important server chip announcement in years. At [MWC 2026 in Barcelona](https://www.mwcbarcelona.com/), the company officially previewed the **Xeon 6+ “Clearwater Forest”** — a 288-core monster built on Intel’s brand-new 18A process node, designed specifically for 6G infrastructure and edge AI workloads. It launches in H1 2026.

## Why This Chip Is Different From Everything Before It

Clearwater Forest isn’t just a spec bump — it’s Intel’s manufacturing comeback moment. Built at **Fab 52 in Arizona**, it’s the first mass-production 2nm-class chip ever made in the United States, using Intel’s new 18A process with RibbonFET transistors — Intel’s first new transistor architecture in over a decade.

The packaging is equally groundbreaking. Unlike all previous Xeon generations that used EMIB (2D bridges between dies), Clearwater Forest uses **Foveros Direct 3D** — actual 3D stacking of compute tiles on top of active base dies. This dramatically reduces signal distance, cuts power loss, and allows 12 compute tiles to be packed into a single socket. Each tile has 24 Darkmont E-cores, for a total of 288 per socket.

The Darkmont E-core itself is a two-generation leap over the Crestmont cores in Sierra Forest — featuring a 9-wide decoder (up from 6-wide), double the integer ALUs, and enhanced floating-point units. That’s where the 17% IPC gain comes from.

For telcos and 6G infrastructure builders, the headline is the **38% rack power reduction** and **60% better performance per watt** vs the previous dual-socket Sierra Forest platform — tested by [Ericsson](https://technosports.co.in/?s=Ericsson). Built-in Intel AMX and vRAN Boost acceleration eliminate the need for discrete AI accelerators entirely. As TechnoSports has noted, operators like Rakuten Mobile and Vodafone are already adopting Xeon 6 for live vRAN deployments.

## FAQs

### **When will Intel Xeon 6+ Clearwater Forest launch?**

Intel confirmed a H1 2026 launch, manufactured at Fab 52 in Chandler, Arizona on the Intel 18A process.

### **How does Clearwater Forest compare to its predecessor Sierra Forest?**

A single Clearwater Forest socket delivers 60% more performance per watt and 38% lower rack power vs a dual-socket Sierra Forest configuration — cutting both cost and energy in half.
