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

Zhaoxin has officially launched its next-generation KX-6000G High-Performance & KH-40000 Server CPUs in China’s domestic PC market.

China Goes Up to 32 Core Server & 4 Core High-Performance PC CPUs By Zhaoxin

China’s domestic chip maker, Zhoaxin, has announced the official launch of its next-generation CPU lineup targeting the server and consumer PC segment. The two chips are based on the 16nm node and are intended for a diverse portfolio of workloads. First we have the Kaisheng KH-40000 server chip family that includes up to 32 cores and can be used in a two-socket configuration with up to 64 cores. Then we have the standard consumer components, the Kaixian KX-6000G aimed at high-performance PCs and embedded platforms with a total of four cores and internal graphics.

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

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