WuDaoKou is largely a brand new architecture designed by Zhaoxin. This is a departure from earlier microarchitectures such as {{\\|ZhangJiang}} which were a lightly modified version of [[VIA Technologies]] ([[Centaur Technology|Centaur]]) architecture. WuDaoKou is a new and complete [[SoC]] design. Whereas prior processors had separate [[dies]] connected together over the legacy [[front-side bus]], the new design is a single-die [[system-on-a-chip]] design that features [[8 cores|8]] integrated [[x86]] cores consisting of two clusters of four cores each connected over a new point-to-point crossbar, improving the internal bandwidth and latency considerably. The new chip also integrated the memory controller and the rest of the [[north-bridge]] on-die as well which further improved latency, bandwidth, and performance. The new chip also has an [[integrated graphics processor]] supporting 4K resolution and up to three screens via an array of display ports.
 
  
 
Overall, [[Zhaoxin]] has reported the new microarchitecture to have 25% improvement in [[IPC]], 140% improvement in multi-core workloads, and 120% higher memory access bandwidth.
