AMD新一代的處理器架構 Zen,確定的是它明年會使用FinFET生產,
但AMD官方並沒有提過到底是16nm還是14nm,這給人留下了豐富的想像空間,
因為AMD兩家代工夥伴TSMC及Globalfoundries的製程並不同,
TSMC我們知道有16nm FinFET及高效能的16nm FinFET Plus兩種製程,
而GF的FinFET授權自三星,有低功耗的14nm LPE及高效能的14nm LPP之分。
最近在LinkedIn上,某個AMD工程師的履歷上洩露了部分天機,
AMD已經成功地流片了包括Zen及自研的ARM架構 K12晶片,
同時他在不同製程上有豐富的物理設計經驗,
重點來了——在這部分內容中他提到了16/14nm FinFET。
這裡說的是CPU工程師,由此可以看出AMD新一代的CPU也是有16nm及14nm兩種製程設計。
此外,能為此提供佐證的還有AMD高管在財報會議上的說法,
AMD CEO蘇姿丰提到今年Q3季度他們已經有多個產品使用FinFET製程流片了,
她用的一個說法是“ both of”,也就是說TSMC及GF兩個代工夥伴中都流片了FinFET製程
的產品。
雖然不能100%確定她說的一定是Zen架構處理器,
但FinFET的另一個產品K12是ARM架構的,
而且官方已經推遲到了2017年,Zen架構才是2016年的,
再加上CPU工程師的履歷,所以最有可能的還是在指Zen架構處理器。
至於GPU晶片,AMD也確定會使用FinFET製程,但同樣沒提及會交給TSMC還是GF代工,
以往AMD的GPU都是TSMC代工的,但GF在14nm上得到了三星的幫助,不像以前那麼坑了,
AMD早就有意把所有產品都轉移到GF代工,畢竟後者流過AMD的血,雙方的合作更親密,
所以不排除明年的新一代GCN架構顯卡也存在兩種製程版本的可能。
