   Introducing the Next Generation of Clearwater Forest Processors

   Enhanced Performance and Features

   The upcoming Clearwater Forest processors from Intel are set to revolutionize the data center industry with their advanced capabilities. These new chips will support up to 12-channel DDR5 memory with speeds of up to 8000 MT/s, a significant improvement over the previous generation. Additionally, the platform will feature up to 6 UPI 2.0 links with speeds of up to 24 GT/s per lane, up to 96 PCIe Gen5.0 lanes, and up to 64 CXL 2.0 lanes.

   Security and Power Management Innovations

   In addition to the performance upgrades, the Clearwater Forest processors will come equipped with Intel Software Guard Extensions (SGX) and Intel Trust Domain Extensions (TDX) to enhance security measures. On the power management front, these chips will include Intel Application Energy Telemetry (AET) and Intel Turbo Rate Limiter. Moreover, Advanced Vector Extensions 2 with VNNI and INT8 support will be integrated into the new CPUs.

   Seamless Upgrades for Existing Servers

   For those who have already invested in Sierra Forest servers, the good news is that Clearwater Forest processors will be socket-compatible with the prior generation. This means that users can easily upgrade their servers by simply swapping out the chips and performing a BIOS flash. According to Boyko, a representative from Intel, “The number one feedback we got from OEMs was we don’t want to do a new server. We want it to be socket compatible with the servers we’ve already deployed.”

   Availability and Conclusion

   Clearwater Forest processors are expected to hit the market in the first half of 2026, offering unparalleled performance, security features, and power management capabilities. With seamless upgrades for existing servers, Intel is paving the way for a more efficient and cost-effective data center infrastructure.
