After showcasing the physical chip at the 2025 Yunqi Conference and the China International Communications Exhibition, Zhaoxin has now unveiled more in-depth specifications for its KH-50000 KHENGSHENG series processors.

This processor series utilizes Chiplet packaging technology, boasting up to 96 cores per socket. The base frequencies are set at 2.2GHz for the 96-core version and 2.6GHz for the 72-core version, with a maximum operating frequency reaching 3.0GHz. Additionally, it offers up to 384MB of L3 cache.

In terms of memory support, the processors are compatible with 12-channel DDR5 5200 ECC memory, with a maximum capacity of 3TB. For interface options, they provide 128 lanes of PCIe 5.0 (supporting both CXL and Zhaoxin's proprietary ZPI interconnect), 16 lanes of PCIe 4.0, 4 USB 3.2 Gen2 ports, and 12 SATA 3.2 high-speed interfaces.

When it comes to scalability, the processors support efficient dual-socket or quad-socket expansion interconnects. This enables a single server to house up to 4 processors, creating a high-performance computing platform with up to 384 cores.

Security is a top priority, with the processors supporting Zhaoxin's proprietary SM2, SM3, and SM4 national cryptographic acceleration instructions. They also incorporate security technologies such as secure boot and key management, while enhancing server RAS (Reliability, Availability, and Serviceability) functionality. Furthermore, they integrate Nationz Technologies' fourth-generation trusted computing solution, achieving secure computing co-packaging. This meets China's GM/T 0012-2020 cryptographic module requirements and complies with the TPM 2.0 international standard.

The series maintains seamless compatibility with the x86 instruction set, supporting extended instructions such as SSE4.2, AVX, and AVX2. It is also compatible with mainstream server operating systems like Kylin, Unity, and Zhongke Fangde. This compatibility enables the construction of cloud-side and edge-side computing platforms, including high-performance general-purpose servers, high-density AI servers, high-density storage servers, and high-performance workstations. These platforms are designed to meet core application demands in AI, cloud computing, data centers, and large-scale storage.
