Intel has just launched the Xeon 6 performance core series, codenamed Granite Ridge, alongside the earlier released Xeon 6 efficiency core series (Sierra Forest), creating a new data center platform. Both have upgraded to the new Intel 3 (compute module) and Intel 7 (IO module) manufacturing processes, marking the latter’s debut.
At an enterprise technology conference in Portland, Oregon, Intel showcased the next-generation Xeon processor Clearwater Forest samples, expected to be named the Xeon 7 series.
The core compute module features a total of five modules (core count unknown), manufactured using Intel’s 18A process (equivalent to 1.8nm), making it the first mass-produced product of this process.
Additionally, the base module uses the Intel 3-T process, an upgraded version of Intel 3, incorporating TSV (through-silicon via) technology for 3D stacked packaging.
Clearwater Forest will continue to utilize the LGA7259 package interface introduced with Xeon 6, which is quite large.
Notably, Intel recently announced the cancellation of the 20A process node, citing the smooth progress of the 18A node, with defect density (D0) now below 0.40, making it ready for mass production, including Clearwater Forest and the consumer-grade low-power Panther Lake.
However, the Arrow Lake Core Ultra 200 series high-performance processors will have to rely entirely on TSMC’s 3nm process.
The 18A node is seen by Intel as the key to surpassing TSMC, meaning the company’s future success hinges on this critical development amidst current challenges.
