The next non-Pro iPhones may arrive with a hidden compromise. The iPhone 18 and iPhone 18e are rumored to ship with 9GB of RAM, a level that could restrict access to Apple’s most advanced AI features in iOS 27.
That detail comes from Apple analyst Ming-Chi Kuo, who says the two entry-level models will still use the A20 chip built on 2nm manufacturing. The difference lies in memory configuration, which appears to be more conservative than what Apple plans for the Pro line.
9GB RAM puts the standard models in a different lane
According to the report, the iPhone 18 and 18e will use six 1.5GB memory dies, bringing total RAM to 9GB. That is an increase from 8GB on the standard iPhone 17, so the new models would still see a modest upgrade.
The gap to the Pro models is larger. Kuo said the iPhone 18 Pro line is expected to use eight 1.5GB dies for a total of 12GB RAM, giving those devices more headroom for heavier on-device workloads.
| Model | Reported RAM | Memory Setup |
|---|---|---|
| iPhone 17 | 8GB | Standard model baseline |
| iPhone 18 / 18e | 9GB | Six 1.5GB dies |
| iPhone 18 Pro | 12GB | Eight 1.5GB dies |
Why iOS 27 could draw a line between models
The concern is tied to Apple Intelligence and the next generation of Siri. Some of the most advanced AI functions are said to require at least 12GB of RAM to run properly on the device itself.
Those features reportedly include real-time language processing, smarter context analysis, and deeper integration with third-party apps. With 9GB, the iPhone 18 and 18e may still support many AI functions, but not the most demanding ones.
That would leave non-Pro buyers with a more limited version of the software experience. Apple may still keep core AI tools available, while reserving the most capable features for the Pro tier.
Cost pressure appears to be shaping the lineup
The memory decision also fits a wider cost-control pattern. Rising component prices are said to be pushing Apple to trim non-Pro specifications while preserving attractive pricing on its mainstream phones.
At the same time, prices for the MacBook, iPad, HomePod, and Apple TV have already increased globally since 26 June 2026. The biggest jump was seen in the 16-inch MacBook Pro, which rose by USD 500 to USD 2,999.
The iPhone line has not yet seen a price adjustment. That suggests Apple still wants to protect the iPhone’s position as its most important consumer product while absorbing some of the hardware cost pressure elsewhere.
The Pro model remains the safer choice for AI-heavy users
In this scenario, the iPhone 18 Pro stands out as the most complete option for users who want full access to future AI features. Its 12GB RAM target appears better aligned with iOS 27 capabilities that run locally on the device.
The iPhone 18 and 18e would still offer the usual mix of performance, efficiency, and a lower entry price. The trade-off is that the most advanced AI tools may remain exclusive to the Pro family.
Apple has not announced any official details yet, so the 9GB RAM figure and the possible AI limitation remain rumors for now. The clearest confirmation, if it comes, may arrive at WWDC 2026.
