'''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|via_technologies/microarchitectures/isaiah|l1=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]] {{via|Isaiah|l=arch}} and were manufactured on a [[40 nm process]]. For all practical purposes, those chips are identical to VIA's {{via|Nano}} 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|zhaoxin/microarchitectures/zhangjiang|l1=ZhangJiang microarchitecture}}
ZX-C which is based on the {{zhaoxin|ZhangJiang|l=arch}} microarchitecture introduced a number of enhancements including extending the architecture to support up to [[8 cores]]. With many respect they are very similar to VIA's {{via|QuadCore}}. Since those parts were manufactured on TSMC's [[28 nm process]], they have lower power consumption and thus higher clock speed. ZX-C entered mass production on January 12, 2018 meaning they are qualified for 100,000 operating hours (roughly 11.5 years) and government procurement.

=== KaiXian KX-5000 ===
{{main|zhaoxin/microarchitectures/wudaokou|l1=WuDaoKou microarchitecture}}
Announced at Semicon China 2017, the KX-5000 (formerly ZX-D) introduces the largest set of the improvements. Those SoCs are based on {{zhaoxin|WuDaoKou|l=arch}}, fabricated on [[HLMC]]'s 28nm, and is considered the first truly zhaoxin-developed architecture. Among the many improvements such as higher integration (incorporating the [[GPU]] and [[memory controller]] on-die), those processors now support dual-channel DDR4 memory and support supports HD 4K decoding.

=== KaiXian KX-6000 ===
{{main|zhaoxin/microarchitectures/lujiazui|l1=LuJiaZui microarchitecture}}
The KX-6000 (formerly ZX-E) is a planned series of processors based on {{zhaoxin|LuJiaZui|l=arch}} set to be fabricated on [[TSMC]]'s [[16 nm]].
