Intel’s Clearwater Forest Xeon 6+ CPUs Enter Production with 288 Cores

Intel has officially commenced full production of its Clearwater Forest Xeon 6+ CPUs, marking a significant moment for the company's data center offerings. Featuring an architecture with up to 288 Darkmont E-Cores, these processors are tailored to address the rising demands of 6G and Edge AI applications. Set to launch later this year, Clearwater Forest plays a crucial role in Intel's strategy to improve performance and efficiency in data-intensive environments.

The Clearwater Forest CPUs utilize Intel's advanced 18A process technology, which also supports other upcoming products like the Panther Lake Core Ultra Series. This new generation of processors is designed to excel in data centers, providing stable support for workloads that require high core counts and effective power management. With specifications that include a substantial 576 MB of on-package L3 cache and 288 MB of L2 cache, the Xeon 6+ is built for optimal performance.

In terms of architecture, the Clearwater Forest lineup consists of 12 compute chiplets, each outfitted with advanced technologies such as RibbonFET, Power Via, Foveros Direct3D, and EMIB 2.5D. The CPUs support up to 12-channel DDR5 memory, achieving speeds of up to 8000 MT/s. This setup not only boosts memory bandwidth but also ensures scalability and flexibility for various server configurations.

Performance Enhancements

Testing conducted by Ericsson showcases the Clearwater Forest’s capabilities, revealing that a single Xeon 6990E+ chip can achieve a 38% reduction in runtime rack power while delivering over 60% greater performance per watt compared to its predecessor, the dual-socket Xeon 6780E Sierra Forest. Such efficiency improvements are essential for modern data centers, where operational costs and energy consumption are critical concerns.

The architectural innovations extend beyond core counts and power efficiency. Clearwater Forest chips support up to 96 PCIe Gen5 lanes and 64 CXL 2.0 lanes, providing extensive connectivity options for high-speed data transfer and integration with various peripherals. The platform's compatibility with the LGA 7529 socket in both single and dual-socket configurations allows for versatile deployment in a range of server environments.

Compatibility with Emerging Technologies

Intel’s oneAPI Toolkit will fully support Clearwater Forest, enabling developers and enterprises to maximize the performance capabilities of the new chips. The toolkit offers a unified programming model across Intel's hardware platforms, including Xeon, Core Ultra, and Arc GPUs, which is vital for optimizing workloads in AI and machine learning applications.

The introduction of Clearwater Forest arrives at a time when data centers are increasingly challenged with handling complex AI workloads and massive data streams. With its advanced specifications and focus on efficiency, Intel’s Xeon 6+ is poised to help organizations tackle these challenges effectively.

Availability and Future Prospects

Expected to launch later this year, the Clearwater Forest CPUs will be included in various server offerings, such as Dell’s PowerEdge R9810/R9820 models. These servers promise memory bandwidth improvements of up to 12,800 MT/s, effectively doubling the capabilities of previous generations.

As Intel progresses with the Clearwater Forest launch, the company is not only enhancing its product lineup but also reaffirming its commitment to innovation in the data center sector. With growing competition in the CPU market, the performance and efficiency gains offered by Clearwater Forest may well set new benchmarks for future data processing capabilities.
