Apple plans to introduce the iPhone 18 Pro and iPhone 18 Pro Max models this fall. Standard iPhone 18 And iPhone 18e According to allegations, it will arrive in the spring of 2027. However, the real question revolves around whether these two models can run Apple’s new Siri AI features. Because for two advanced features in iOS 27 12GB RAM limit is being discussed.
TF International Securities analyst Ming-Chi Kuo predicts Apple’s more affordable 2027 iPhone models with A20 processors 9GB RAM states that he will use it. Thus, Apple has updated the current standard iPhone 17 models. 8GB RAM will raise its level. However, Forbes and MacRumors state that this increase does not reach the memory level desired by the AFM Core Advanced model. Because iPhone 18 And iPhone 18emay exclude some Siri AI innovations.
The key technology Apple uses here stands out as the AFM 3 Core Advanced model. The company describes this model as one of the most powerful base models running on the device. In addition, Apple’s research note shows that the model uses a sparse architecture with 20 billion parameters and introduces 1 to 4 billion parameters in each process. While this choice provides faster response in Siri and dictation features, it directly increases the memory requirement.
Advanced Dictation Preview is in iOS 27 beta iPhone 17 Pro, iPhone 17 Pro Max And iphone air working on it. What these models have in common is 12GB RAM to reach the level. In contrast, the standard iPhone 17 and iPhone 16 Pro, 8GB RAM You cannot get this feature with . Therefore in 2027 9GB RAM The possibility of a similar limit for the iPhone 18 and iPhone 18e, which are said to be carried, remains on the table.
12 GB RAM limit divides the iPhone 18 family into two
Advanced Dictation Preview automatically edits punctuation and capitalization when converting speech to text. Additionally, the feature aims to improve text accuracy while the user continues speaking. Apple’s new expression-adjusted Siri voices focus on making the assistant’s tone, speed and emphasis more natural. Therefore, the difference in iOS 27 is not limited to a faster Siri experience.
According to the information provided by Kuo, Apple will switch to a 1.5 GB x 6 memory layout in the A20-based lower-end 2027 iPhone models. So the total capacity 9GB RAM will rise to the level. Current A19-based standard models are in 2 GB x 4 layout. 8GB RAM is using. However, this increase stands out for AFM 3 Core Advanced. 12GB RAM falls behind the needs.
On the Pro models side, the situation is different. Kuo, iPhone 18 Pro, iPhone 18 Pro Max and Apple’s first foldable iPhone model 12GB RAM He says he will come with. Thus, Apple can create a clear distinction in terms of Siri AI features within the same iPhone generation. Since the company has not yet introduced the iPhone 18 family, this distinction does not constitute an official statement.
This difference on the memory side is not only explained by the distinction between product classes. Apple increased the prices of Mac and iPad models due to the increase in RAM and NAND prices. Analysts say that iPhone 18 Pro models also have approximately 200 dollars An increase in the level is expected. On the other hand, the fact that Apple is looking to the Chinese CXMT side for RAM supply shows that the company is trying to reduce supply pressure.
iPhone 18 and iPhone 18e can offer more powerful hardware than current standard models with 9 GB RAM. However Siri AI, Advanced Dictation Preview and if the spoken threshold for emoticon-adjusted Siri voices does not change, these two models may not receive some iOS 27 features. Apple’s Pro announcement in fall 2026 and the standard iPhone launch in spring 2027 will clarify this difference. The final version of iOS 27 will also reveal which models will run the AFM 3 Core Advanced model.
