KaisHeng (KH) is a family of x86 microprocessors developed by Zhaoxin for the Chinese market. This family is primarily targeting server and networking devices.

Overview

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.

Models

KH-20000

Main article: WuDaoKou microarchitecture

The KH-20000 (KH-20k) series is based on the WuDaoKou 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: VT-x/EPT, TXT
• Mem: Up 64 GiB of dual-channel 2133 MT/s DDR4
