WuDaoKou is the successor to Zhangjiang, a 28 nm x86 microarchitecture designed by Zhaoxin for mainstream laptops, desktops, and servers.

Family	Series	Description
KaiXian	KX (5000)	Desktop, Laptops
Kaisheng	KH (20000)	Storage, Servers

WuDaoKou is manufactured on HLMC's 28 nm process.

8 cores per die (up from 4)
SoC design
- New Uncore
  - northbridge moved on-die
  - PCIe 3.0 (from 2.0)
  - DDR4 (From DDR3)
- New integrated graphics processor
  - HD Audio Output/Codec
Core
- Pipeline was reduced by 5 stages
- Execution engines were re-balanced
- Branch prediction unit was reworked and optimized
FSB removed
- x4 PCIe 3.0 communication with southbridge chipset
Chipset
- Gigabit Ethernet port (RGMII)
- USB 3.1 Gen2 (Type-C) ports
- SATA 3.0 ports
