Succession

LuJiaZui is the successor to WuDaoKou, a 16 nm x86 microarchitecture designed by Zhaoxin for mainstream laptops, desktops, and servers.

Etymology[edit]

As with prior microarchitectures, LuJiaZui is named after the Lujiazui station of the Shanghai Metro. The station is located in the highly prosperous Pudong district of Shanghai.
