14nm+++工藝可以退休了Intel的10nm SF工藝能效高出35%

Intel的14nm工藝可以說是DIY玩家的老朋友了,從2015年量產到現在都6年了,期間Intel
魔改了三代,最新的是14nm+++工藝,依然是當前桌面Core處理器的主力。
10nm工藝好事多磨,2.7倍的晶體管密度指標史無前例,但也帶來了量產上的難題,導致
10nm工藝這兩年才開始量產,去年開始生產的是10nm SuperFin工藝(簡稱10nm SF),也
就是第二代10nm工藝了。
10nm SF工藝相比14nm+++工藝到底有多大的提升呢?最近有B站UP主作了個測試,對比了
Core i5-11400H(10nm SF工藝Willow Cove架構)與桌面版的Core i5-11400(14nm+++工
藝、CypressCove架構)處理器的性能、功耗差距。
Core i5-11400H在52W功耗下頻率3.52GHz,Core i5-11400在77W功耗下頻率3.4GHz,這時
候二者的R20性能差不多,算下來10nm SF的能效提升了35%左右。
當然,較真的話,Core i5-11400的架構跟Core i5-11400H的也不完全一樣,但後者的
WillowCove架構基本上是改進了緩存系統,影響不大。
排除這些細微差距,目前來看10nm SF工藝的提升還是挺明顯的,下半年就要上12代Core
Alder Lake了,除了會升級GoldenCove高性能架構之外,傳聞工藝也會進一步升級到
10nm ESF,也就是增強版的10nm SF,值得期待。
