根据Wiki-Chip 台积7nm与5nm制程包括:
N7 (DUV)
N7P (DUV): +7% speed @iso-power/-10% [email protected] vs N7
N7+ (EUV): +10% speed @iso-power/-15% [email protected] vs N7
N5: +15% speed @iso-power/-30% [email protected] vs N7 (2020量产)
N5P: +7% speed @iso-power/-15% [email protected] vs N5 (2021量产)

而从EE Times之前的分析 Zen2采用的是N7制程

如果属实 而Zen3又没有采用N7P.N7+来加强效能
(发表会上19%IPC的进步剖析没有写制程改善 CTO也说是same 7nm process)
那等到Zen4切台积的N5制程
Zen3
