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

Zhaoxin has officially unveiled its next-generation KX-6000G high-performance and KH-40000 server CPUs for the Chinese domestic PC market.

Zhaoxin China gets up to 32 cores for servers and 4 cores for high-performance PC CPUs

China’s domestic chipmaker Zhoaxin has announced the official launch of its next-generation CPU lineup, targeting the server and consumer PC segment. Both chips are based on a 16nm node and are designed for a diverse portfolio of workloads. First up we have the Kaisheng KH-40000 server chipset family which has up to 32 cores and can also be run in a dual socket configuration up to 64 cores. Then we have the most popular consumer parts, the Kaixian KX-6000G, which is designed for high-performance PCs and embedded platforms with a total of four cores and integrated graphics.

Server processor based on a new generation of Yongfeng 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 dual-channel 64-core connectivity, and access memory bandwidth of up to 200GB/s.
