Quit making excuses for this shit . <| sep |> come on and jump , go head and jump <| sep |> Even if they live up to the hype they won ' t have the same IPC as intel and won ' t hit low TDP requirements for notebooks . Intel does have an advantage in both areas that is quite hard to reach , and still has a process advantage for the next few years marketing numbers of 161410 nm aside , and Apple is not one to concern itself with cost as much as what ' s best . AMD also hasn ' t historically reliably been able to ship in volume , which Apple needs . A more subtle , secondary point to this is switching to Zen means supporting all the platform and architecturespecific optimizations , errata , firmware , and drivers on two different platforms . This includes an entirely different chipset along with different CPU instructions . This can wreak havoc and cause all sorts of delays witness Skylake issues earlier this year that delayed the release of MBPs . This is an added burden on a platform Mac that Apple isn ' t focusing on a great deal anymore , so it doesn ' t make sense they ' d switch unless there was a significant increase in a performance , b availability of chips at volume and at the right time , andor c control of key technologies . Going to Zen would only be a lateral move , while both b and c are reasons why they ' d switch to Ax processors .
