China Modifies Intel Xeon 6P "Granite Rapids" Processors for Domestic Security

Montage Technology has unveiled the Jintide C6P CPU family, a line of server processors that repurpose Intel's "Granite Rapids" Xeon 6 design with added security and tracking features for the Chinese market. The company stated that the chips are designed for regulated sectors, including government, healthcare, and finance, where hardware-level controls and customizability are most critical. Montage framed the launch as the next step in a long-running collaboration that includes Tsinghua University and a special agreement with Intel, under which Montage can reconfigure and commercialize certain Xeon processors domestically. The C6P family maps to Intel's sixth-generation Xeon Scalable P-core lineup and appears to use Granite Rapids-SP silicon, the same foundation for Intel's Xeon 6700 and 6500 series.

Montage previously released a C6E series based on Sierra Forest E-cores and has now shifted to P-core parts for workloads that prioritize single-thread performance. Promotional images showed a C6787P, which follows Montage's convention of prefixing Intel SKUs with a C. The underlying Xeon 6787P is an 86-core, 172-thread design with roughly 336 MB of L3 cache. Platform features carried over from Granite Rapids include two-socket scalability, eight memory channels with support for high-speed DIMMs, many PCIe 5.0 lanes, and CXL 2.0 compatibility. Montage also states that it has embedded China-specific encryption, decryption, and monitoring capabilities at the chip level to meet local compliance requirements. This likely comes in the form of a nearby chip placed on the CPU package, below the ISH. The company has not yet published detailed specifications, pricing, or certification dates and has not confirmed whether the higher-core Granite Rapids-AP dies will be adapted to the domestic needs.
