Sources at Taiwanese motherboard makers told DigiTimes that they're concerned the late arrival of AMD's Zen architecture may put the chip designer in a rather difficult competitive position. As it stands right now, it appears Zen will not start shipping until Q4 2016 at the earliest. The site heard issues with Globalfoundries' 14nm process may be to blame for the late launch of Zen.
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.
