Bulldozer was a epic blunder bust fail so AMD's Zen copied Intel in many but not all ( Intel Ring Bus) µarch features, but again it will be too little and too late to compete with Skylake's new µarch and much improved performance.
AMD's Zen will be a cheap lower performing meager margin inferior Intel copy, better than Bulldozer but nowhere near Skylake's µarch. AMD R&D is so flawed that it needs to copy Intel to keep from designing another blundering Bulldozer, AMD is indeed doomed.
Nobody is paying anyone to bash AMD but AMD marketing is paying viral propaganda pumping puppets to infest tech sites and investment boards. AMD needs to be in BK reorg court ASAP so we can clear these paid AMD pumpers from the face of the Earth.
