Zhaoxin's in-house server processor, the Kaisheng KH-50000, has won both a first prize in a specialist category and the gold award in the grand final at the 2026 (third) Jin Lingguang Cup China Internet Innovation Contest[1]. It packs 96 cores into a single socket alongside 12 channels of DDR5 and 128 lanes of PCIe 5.0, making it the current flagship among Chinese domestic server CPUs.

Two awards from one contest

The contest is the third edition of the Jin Lingguang Cup China Internet Innovation Contest, organized by the Internet Society of China. It is positioned as an authoritative competition in China's digital technology field, aimed at surfacing strong science and technology projects[1].

The KH-50000 collected a first prize in the information technology application innovation category and the gold award in the grand final. Six academicians, holders of China's highest academic title, sat on the final judging panel, and Zhaoxin says the chip was recognized for its technical independence, overall product strength, and industrial value[1].

This is not the processor's first award. It follows a 2025 People's Craftsmanship Product citation and a 2026 China IC Design Achievement Award for processor of the year, and the chip now serves as the public face of domestic server silicon inside China[1].

96 cores per socket, up to 384 cores in a four-socket box

Official specifications show a genuinely server-class design. Four core counts are offered, at 96, 72, 64, and 48 cores, none of which support simultaneous multithreading, so core count and thread count match[2].

The 96-core part has a 2.2GHz base clock, while the 72-core and lower parts run at 2.6GHz. All of them top out at 3.0GHz. Level 3 cache is 384MB on the 96-core and 72-core parts, 256MB on the 64-core part, and 128MB on the 48-core part[2].

Memory support covers 12 channels of DDR5-5200 RDIMM with ECC, up to 3TB in total. Expansion comes from 128 lanes of PCIe 5.0 plus 16 lanes of PCIe 4.0, with the PCIe 5.0 side also supporting CXL 2.0. There are 4 USB 3.2 Gen2 ports and 12 SATA 3.2 ports[1][2].

A proprietary interconnect enables two-socket and four-socket configurations, so a single server carrying 4 KH-50000 chips reaches 384 cores in total[1]. The package is LGA and measures a sizable 72mm by 76mm[2]. The instruction set covers x86 and 64-bit, with extensions up to SSE4.2, AVX, and AVX2[2]. The absence of AVX-512 will matter for some workloads.

Cryptography built into the hardware

Security is the feature set Zhaoxin pushes hardest. The company has implemented its own acceleration instructions for China's national cryptographic algorithms, including SM2, SM3, SM4, and SM9, embedding cryptographic processing directly into the CPU hardware[1].

The chip also supports secure boot, key management, full hardware memory encryption, trusted computing, and confidential computing. It is designed to meet the requirements of China's GM/T 0012-2020 standard for cryptographic modules, a clear signal that government and financial deployments with strict data handling rules are the target[1].

The ZX86 path and a widening list of adopters

Zhaoxin has spent more than a decade on general-purpose processors of its own design and says it controls 11 core technologies in house, including the instruction set, core microarchitecture, high-speed interconnect, and high-performance IP. The company bundles these into an intellectual property system it calls ZX86, framing its approach as independent without being closed off and compatible without being dependent[1].

The KH-50000 has already completed compatibility work with mainstream Chinese server operating systems, cloud platforms, databases, and AI hardware. Compared with Zhaoxin's previous server CPU, the company reports large gains in database processing, cloud desktop services, and AI training and inference, and says a single machine can sustain IOPS in the tens of millions[1].

Adoption is spreading. Partners including Lenovo's Kaitian brand, ZTE, and Unisplendour have shipped AI servers, general-purpose servers, high-density storage servers, and AI workstations built on the chip, aimed at government, finance, education, energy, power, transportation, telecommunications, and healthcare[1].

Summary

The KH-50000 is built to a specification that squares up directly against mainstream international server CPUs: 96 cores, 384MB of level 3 cache, 12-channel DDR5, and 128 lanes of PCIe 5.0. The two awards reflect both that specification and the deployment record it has built inside China. It is not a product you will find on sale in Japan, but it is a useful yardstick for how far a Chinese server CPU descended from the x86 lineage has come.
