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[edit]

KH-20000[edit]

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
