The sources believe Zen architecture's late release is due to Globalfoundries' issues with R&D and yield rates for its 14nm FinFET manufacturing process.
The Zen architecture is expected to achieve a 40% improvement in performance compared to AMD's existing x86 architecture and will be able to support simultaneous multi-threading (SMT). The new architecture also adopts a new cache subsystem to boost CPU efficiency.
