Zhaoxin has officially introduced its next-generation KX-6000G High-Performance & KH-40000 Server CPUs for China's domestic PC market.

China Gets Up To 32 Core Server & 4 Core High-Performance PC CPUs By Zhaoxin

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