KaiXian (ZX/KX) is a family of x86 microprocessors developed by Zhaoxin for the Chinese market.

Overview

KaiXian is a family of x86 microprocessors designed by Zhaoxin as part of China's national security initiative which attempts to reduce the reliance on foreign technology (e.g., Intel) and to gain greater control over their intellectual property. Those processors are x86-compatible with Intel's processors and are capable of booting all modern operating systems such as Red Hat Enterprise Linux and Windows 10.

Models

KaiXian ZX-A

Main article: VIA's Isaiah

KaiXian ZX-A were the first series of processors released by Zhaoxin. Those processors were based on the same architecture as VIA Technologies Isaiah and where manufactured on a 40 nm process. For all practical purposes, those chips are identical to VIA's Nano X2 and QuadCore parts.

KaiXian ZX-B

ZX-B series models were identical to ZX-A except that they are fabricated in mainland China on HLMC's 40 nm process.

KaiXian ZX-C

Main article: ZhangJiang microarchitecture

ZX-C which is based on the ZhangJiang microarchitecture introduced a number of enhancements including extending the architecture to support up to 8 cores. Since those parts were manufactured on TSMC's 28 nm process, they have lower power consumption and thus higher clock speed.
