== Overview ==
 
[[File:zhaoxin kh roadmap.jpg|right|400px]]
 
Announced in late [[2017]] and officially launched in early [[2018]], the KH series is primarily designed for general-purpose servers. Those chips are fully SoCs solutions that come with an optional I/O extension chipsets.

=== KH-20000 ===
 
{{main|zhaoxin/microarchitectures/wudaokou|l1=WuDaoKou microarchitecture}}
 
The KH-20000 (KH-20k) series is based on the {{zhaoxin|WuDaoKou|l=arch}} microarchitecture and is fabricated on [[HLMC]]'s [[28 nm process]]. Those parts all include the following common features:
 
 
* '''ISA:''' Everything up to AVX (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, SM3, SM4, and AVX)
 
* '''Tech:''' {{intel|VT-x}}/{{intel|EPT}}, {{intel|TXT}}
 
* '''Mem:''' Up 64 GiB of dual-channel 2133 MT/s DDR4
