根據Wiki-Chip 台積7nm與5nm製程包括:
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量產)
N5P: +7% speed @iso-power/-15% [email protected] vs N5 (2021量產)

而從EE Times之前的分析 Zen2採用的是N7製程

如果屬實 而Zen3又沒有採用N7P.N7+來加強效能
(發表會上19%IPC的進步剖析沒有寫製程改善 CTO也說是same 7nm process)
那等到Zen4切台積的N5製程
Zen3
