曆代A系晶片的性能，大概是什麼水準？看完基本懂了！

衆所周知，手機上的處理器，是決定性能最重要的零部件，就像是人的心髒一樣重要。如果你先挑好晶片，再來買手機，大機率都不會踩雷。

是以我覺得，很有必要針對手機晶片這一個領域，進行深度、易懂的科普。

這期文章我們就來聊聊，曆代 A 系晶片都是什麼水準。因為 iPhone 8、iPhone X 已經被 iOS 17 徹底淘汰，是以我們就從 iPhone XR，也就是 A12 晶片開始講起。

為了讓資料更加真實、可信，CPU以最新的 geekbench6 為準，GPU 以曼哈頓 3.1 為準。同時我們會補充晶片的能效（功耗）資料，并且簡明扼要地給一個結論，讓大家全方面地了解 A 系晶片的綜合實力。

話不多說，那我們現在來開始盤點。

A12：7nm工藝初登場

A12 晶片是蘋果第一款 7nm晶片，同時也是一代人的回憶。作為 18-19 年釋出的旗艦晶片，A12可以說是一代神 U。以至于直到 2022 年，都有人覺得它還可以再戰三年。

根據 Geekbench 6的資料，A12 的CPU 單核是 1335 分，多核為 3130 分，可以了解為骁龍 870 的 89% 性能。最重要的是單核能效，根據 spec 06整數的資料，CPU 大核是 3.59W/45.32分，換算下來單核能效就是12.62。

根據曼哈頓 3.1 的資料，A12的 GPU 跑分為 103.83 FPS，峰值功耗為 5.98W，能效比相當于是 17.36 fps/W。

提個資料，骁龍 8Gen1的大核整數是 3.89W/48.38 分，換算下來單核能效是12.43。這也就意味着，骁龍 8Gen1最關鍵的單核，甚至比 A12還要差點。

A13：一代神 U

A13 最大的亮點，就是在還是 7nm工藝的前提下，性能實作了大幅提升，而且能效也沒拉下太多。再加上骁龍 888 羸弱不堪，聯發科也還沒站起來，成就了它“一代神 U”的威名。

根據 Geekbench 6的資料，A13 的CPU 單核是 1780 分，多核為 4300 分。單核能效方面，根據spec 06整數的資料，CPU 大核整數是 4.61W/52.82分，換算下來單核能效就是11.45——這比 A12 略低一些，但是在可了解的範疇，畢竟還是 7nm工藝。

根據曼哈頓 3.1 的資料，A13的 GPU 跑分為 123.6 FPS，峰值功耗為 7.29W，能效比相當于是 16.95fps/W。可以看出，A13 相當于在 A12 的基礎上，增加性能，同時功耗也在增加，可以了解為改良的超頻版，能效基本維持在原水準。

A14：口碑兩極分化

A14 是令人失望的一代，因為大家原本以為更新5nm工藝後，A14 會再創輝煌，但沒想到是我們預期太高了。

可能是初代 5nm工藝還不成熟，A14 雖然密度大幅增加，但是在高負載下，能效水準并沒太大提升，反而是中低負載下更省電了——當然，這是在跑分軟體上看不出來的。

不管怎麼說，台積電的 5nm，總比三星 5nm要強。   

根據曼哈頓 3.1 的資料，A14的 GPU 跑分為 143 FPS，峰值功耗為 7.3W，能效比相當于是 19.58fps/W——這進步其實也不小。

簡單總結一下，A14 對比A13，性能、能效是雙雙提升了。隻是果粉們預期太高，再加上 iPhone 12 系列又作死，全系降低了電池容量，導緻 A14 的口碑兩極分化。

對了，值得一提的是，A14 有兩個版本，iPad上的 A14性能要高接近 10% 以上。   

A15：同代無敵

如果說 A14 的勝利是帶有争議性的，那 A15 就是毫無争議的同代無敵了。更成熟的N5P工藝，高達 32MB的SLC（比 A14 翻了一倍），每一個細節都透露出“王者的氣息”。

根據 Geekbench 6的資料，A15 的CPU 單核是 2410 分，多核為6150分。單核能效方面，要注意的是，A15 的能效測試算法變了。

根據 spec 2017測試，它的CPU 大核整數是 4.11W/7.28分，能效相當于1.77。要注意，這個數字和剛才的spec 06整數，不是一個算法。作為參考，A14大核為4.35W/6.47分，能效相當于1.49。

而且 A15最大的提升點，在于小核。粗略的看了一下，A15 的小核在能效相近的情況下，性能比 A14 的小核提升了 29%。簡單來說，A15 的 CPU不僅性能更強，而且功耗也更低/持平，妥妥的一代神 U。

買到 iPhone 13 、14的使用者，不再戰個 5 年，都對不起這顆晶片。   

A16：感覺有限

接下來就該講講 A16 了，它采用了台積電 4nm工藝，其實就是第3代 5nm工藝。考慮到 A15 提升這麼全面，A16很難做出較大的改變，畢竟沒有半導體紅利了。

根據 Geekbench 6的資料，A16的CPU 單核是 2650 分，多核為7150分，依然是在穩步提升。能效方面，根據極客灣的spec 2017的資料，算上主機闆功耗的話，A16 的大核能效約為1.79，而 A15 的大核能效約為1.72，提升了大概 4%左右。

GPU 方面就有些擠牙膏了，根據曼哈頓 3.1的資料，A16 的跑分是 197FPS，但是功耗高達 8.47W，能效相當于是23.25fps/W——幾乎和 A15 一樣，用沒提升來形容也不過分。   

但總體來說，A16 還是比 A15 好些的，這一點主要展現在 CPU 單核功耗更低，日常使用體驗更好，但感覺會比較有限。

A17 Pro：蘋果大翻車

任誰都會覺得，首發3nm工藝的A17 Pro，應該就是地表最強晶片了。但是，A17 Pro屬于是蘋果的翻車之作，你可以叫它“火龍果”

首先是 CPU 方面，同樣是 geekbench 6測試，A17 Pro的單核、多核，分别是 2980，7850，看起來還是在穩步提升的。但是問題在于，A17 Pro的能效是沒有進步的。

曼哈頓 3.1 測試，A17 Pro的成績是 204FPS，比上一代隻提升了個位數。性能提升小就算了，功耗也翻了車。

它的 GPU 峰值功耗，提升到了恐怖的9.81W，能效相當于隻有20.79。作為參考，骁龍 8Gen3 的曼哈頓 3.1 是 280FPS，峰值功耗為 10.2W，能效相當于27.45。

GPU性能向來是蘋果的優勢，而 A17 Pro親手推翻了我們的固有印象，3nm真的提升了個寂寞。這下好了，落後友商兩代的，反而變成了蘋果。

最後，關于 A 系晶片的所有資料，我都整理成了表格。

表格長期更新，包括蘋果所有晶片的詳細跑分，友善你第一時間查閱。
