'''Apple A14 Bionic'''是[[苹果公司]]设计，基于64位元[[ARM架构]]的[[系统芯片]]。这款[[SoC]]于2020年9月15日发布，是世界第一款量產的[[5纳米制程|5納米製程]]晶片，首次使用於[[iPad Air (第四代)|第四代iPad Air]]、[[iPhone 12]]和[[iPhone 12 Pro]]以及[[iPad (第十代)|第十代iPad]]。<br />

== 設計 ==<br />
蘋果公司表示，Apple A14 Bionic的[[中央处理器]]的性能比[[Apple A12 Bionic]]快40%，而[[圖形處理器]]则比Apple A12 Bionic快30%。它还包括一个16核的神经引擎（neural engine）和新的机器学习矩阵加速器（machine learning matrix accelerators），性能分别是Apple A12 Bionic的两倍和十倍<ref>{{Cite web|title=Apple unveils all-new iPad Air with A14 Bionic, Apple’s most advanced chip|url=https://www.apple.com/newsroom/2020/09/apple-unveils-all-new-ipad-air-with-a14-bionic-apples-most-advanced-chip/|date=2020-09-15|work=Apple.com|accessdate=2020-09-17|archive-date=2020-09-20|archive-url=https://web.archive.org/web/20200920003224/https://www.apple.com/newsroom/2020/09/apple-unveils-all-new-ipad-air-with-a14-bionic-apples-most-advanced-chip/|dead-url=no}}</ref>，電晶體數量也高達118億個。<br />
<br />
相對上一代的改進是神經網路引擎：全新的16核架構，相比[[Apple_A13|A13]]的8核心數直接翻倍，能夠提供高達11Tops的算力。另外，這次蘋果也為A14 Bionic 引入了和A12Z 類似的機器學習加速器結構， 獲得了更快的矩陣運算速度。<br />
