Zhaoxin Launches KX-6000G High-Performance & KH-40000 Server CPUs For China’s Domestic PC Market

Zhaoxin has officially introduced its next-generation KX-6000G High Performance Server and KH-40000 CPUs for the domestic PC market in China.

China gets up to 32 core servers and 4 core high-performance PC CPUs from Zhaoxin

China’s domestic chip maker Zhoaxin has announced the official launch of the next generation of its CPU generation targeting the server and consumer PC segment. The two chips are based on a 16nm node and target a different portfolio of workloads. We first have the Kaisheng KH-40000 family of server chips, which features up to 32 cores and can also run in a dual-socket configuration with up to 64 cores. Then we have the more mainstream consumer parts, the Kaixian KX-6000G, which targets high-performance PCs and embedded platforms with a total of four cores and onboard graphics.

Server processor based on a new generation of Yongfeng’s self-developed micro-architecture — Kaisheng KH-40000

Kaisheng KH-40000 series processors are based on Zhaoxin’s new self-developed micro-architecture – “Yongfeng”, with a reference frequency of 2.0/2.2 GHz and a maximum operating frequency of 2.7 GHz. A single processor can integrate 32 cores, provide 64MB of cache, support 64-core dual-channel interconnect, and access memory bandwidth of up to 200GB/s.
