Zhaoxin launches KH-50000 server CPUs with up to 96 Cores and quad-socket support

Zhaoxin has officially introduced its new KH-50000 series processors, the company’s most advanced server CPUs to date. Based on a chiplet architecture, the new chips target workloads across AI, cloud, big data, and general-purpose computing.

The KH-50000 integrates up to 96 high-performance cores per socket, split between 12 chiplets and one large IO die. These chiples are said to be running at a base frequency of 2.2/2.6 GHz and boosting up to 3.0 GHz. L3 cache capacity reaches 384 MB, while memory support has been expanded to 12 channels of DDR5 ECC RDIMM with capacities up to 3 TB.

I/O capabilities have also been upgraded, offering 128 lanes of PCIe 5.0 with ZPI/CXL compatibility, 16 lanes of PCIe 4.0, plus SATA 3.2 and USB 3.2 Gen2. The processors retain compatibility with the x86 32/64-bit instruction set, with AVX2 and SM2/SM3/SM4 acceleration supported for cryptographic workloads.

For scalability, the KH-50000 supports both dual- and quad-socket configurations . This enables up to 384 cores in a single server, backed by the new ZPI 5.0 interconnect designed to improve bandwidth while lowering latency and power consumption.

The KH-50000 represents quite a leap compared to the KH-40000 series from 2022, moving from a maximum of 32 cores to 96, upgrading memory support from DDR4 to DDR5, and introducing ZPI 5.0 interconnect technology.
