iPhone 18 同 iPhone 18e RAM 加咗上 9GB，但係仲爭兩個 Siri AI 功能

iPhone 18 同 iPhone 18e 雖然 RAM 由 8GB 升到 9GB，但係因為唔夠 12GB，冇得用 iOS 27 入面兩個最進階嘅 Siri AI 功能：自訂 Siri 語氣同速度，以及大幅提升準確度嘅語音轉文字聽寫。呢個 RAM 限制係蘋果硬件分層策略嘅一部分，同時仲包括首次採用 A20 同 A20 Pro 晶片分家，Pro 版用更勁嘅封裝技術同 12GB RAM。

雖然 iPhone 18 同 iPhone 18e 嘅 RAM 由 8GB 加到 9GB，但係佢哋仍然玩唔到兩個需要至少 12GB RAM 嘅進階 Siri AI 功能。呢個限制背後，仲牽涉到蘋果嘅硬件分層策略、一年兩次嘅發布新節奏，以及市場對 AI 功能碎片化嘅憂慮。

爭咗邊兩個 Siri AI 功能？

預計喺 2027 年春季推出、用 A20 晶片同 9GB DRAM 嘅 iPhone 18 同 iPhone 18e，將會玩唔到 iOS 27 呢兩個需要 12GB 統一記憶體嘅裝置端 AI 功能：

自訂 Siri 語氣同速度——可以按照自己喜好調整 Siri 把聲同講嘢嘅節奏。
大幅提升準確度嘅語音轉文字聽寫——一個效能顯著提升嘅裝置端語音辨識模型。

蘋果喺 WWDC 2026 已經確認咗，呢個最高級別嘅裝置端 AI 引擎最少要用 12GB RAM 。標準版得 9GB，差咗 3GB，所以呢兩個功能只會留畀有 12GB 或以上 RAM 嘅裝置，包括 iPhone 18 Pro、iPhone 18 Pro Max、傳聞中嘅 iPhone Ultra／摺機、iPhone Air、iPhone 17 Pro／Max，以及部分用 M 系列晶片兼至少有 12GB RAM 嘅 iPad 同 Mac 。
