Apple is reportedly planning to increase the RAM in its standard 2027 iPhone models to 9GB, a move intended to better support advanced on-device artificial intelligence features. According to TF International Securities analyst Ming-Chi Kuo, this hardware shift for the base iPhone 18 and iPhone 18e aims to address the growing memory demands of the iOS 27 ecosystem.
Why is Apple increasing RAM to 9GB?
The transition to 9GB of RAM is a direct response to the escalating hardware requirements for Apple Intelligence. While the current iPhone 17 and iPhone 17e utilize 8GB of memory, Kuo notes that the 9GB configuration—comprised of six 1.5GB DRAM dies—will provide the necessary overhead for smoother system-level integration in iOS 27.
How does the iPhone 18 memory compare to the Pro models?
While the standard models are receiving a modest memory boost, Apple’s flagship lineup is expected to maintain a higher hardware ceiling. According to industry reports, the iPhone 18 Pro and iPhone 18 Pro Max will likely continue to ship with 12GB of RAM. The rumored foldable iPhone, often referred to as the iPhone Ultra, is also expected to feature 12GB of memory to handle its unique display and processing requirements.
| Model | Estimated RAM |
|---|---|
| iPhone 18 / 18e | 9GB |
| iPhone 18 Pro / Pro Max | 12GB |
| iPhone Ultra (Foldable) | 12GB |
Will the new iPhone 18 run all AI features?
It remains uncertain whether the 9GB upgrade will be sufficient to run Apple’s most advanced on-device AI models. Apple currently mandates a minimum of 12GB of unified memory for its most sophisticated AI features, which power expressive Siri capabilities and advanced dictation. As of the latest updates, this requirement limits top-tier AI performance to the iPhone Air, iPhone 17 Pro series, M4-powered iPads, and M3-or-later Macs.
Did you know?
Apple’s move to 9GB of RAM represents a shift in die configuration. The current 8GB standard uses four 2GB memory chips, whereas the projected 9GB setup will utilize six 1.5GB dies, according to data shared by Ming-Chi Kuo.
What is the expected timeline for the iPhone 18 launch?
Rumors suggest Apple may alter its traditional release schedule. While the tech giant has not confirmed any changes, speculation indicates a potential split strategy where Pro models debut in September, while standard variants—including the iPhone 18 and 18e—could be reserved for a March launch. These handsets are expected to be powered by the A20 SoC, which analysts suggest will be fabricated using TSMC’s 2nm Gate-All-Around (GAA) process to improve efficiency.
Frequently Asked Questions
- Why does Apple Intelligence require 12GB of RAM?
Apple’s most advanced on-device AI models require high memory capacity for complex tasks like expressive voice processing and advanced dictation, which currently exceeds the 8GB or 9GB thresholds. - Will the iPhone 18e support all iOS 27 features?
While the 9GB of RAM is an upgrade, it may still fall short of the 12GB requirement for the most intensive on-device AI features, according to current hardware trends. - What is the A20 chip?
The A20 is the expected successor to the A19, likely utilizing TSMC’s 2nm GAA fabrication process for better performance and power efficiency.
