Apple’s entry-level iPhone 18 models may get a small but potentially meaningful memory upgrade. According to supply chain analyst Ming-Chi Kuo, the standard iPhone 18 and iPhone 18e will ship with 9GB of RAM, up from the 8GB found in the iPhone 17 and iPhone 17e. That 1GB increase might sound minor, but in the context of on-device AI, it could matter more than it appears.
As reported by AppleInsider, Kuo posted his findings on X, noting that the standard iPhone 18 models will use A20 chips built with 1.5GB x 6 dies, totaling 9GB. The Pro models, the iPhone 18 Pro and iPhone 18 Pro Max, are expected to stick at 12GB using a 1.5GB x 8 die configuration, matching what the current iPhone 17 Pro lineup already offers.
The timing of this rumor is worth paying attention to. Apple announced iOS 27 at WWDC on June 8, 2026, and that update brings a significant expansion of Apple Intelligence, including a rebuilt Siri with genuine AI capabilities. As Apple leans harder into on-device AI, the hardware underneath those features becomes increasingly important.
Right now, the RAM situation with Apple Intelligence breaks down like this:
- 8GB devices (iPhone 17, iPhone 17e) support Siri AI and most Apple Intelligence features in iOS 27
- 12GB devices (iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air) support Apple’s more demanding on-device AI models
- 9GB devices don’t currently exist, so it’s unknown where they would fall
That last point is the real question hanging over Kuo’s report. Apple’s on-device AI models, which run entirely on the device without calling out to the cloud, currently require 12GB of RAM. Devices with 8GB can’t run them. Nobody yet knows whether 9GB would be enough to cross that threshold, or whether Apple would set the cutoff somewhere between 9GB and 12GB.
Kuo’s stated reason for the RAM increase is straightforward: Apple wants the A20-based iPhones to run smoothly under AI workloads. Whether that means better performance within the existing 8GB feature set, access to new features, or something else entirely is still unclear. Apple has not confirmed any of this, and the iPhone 18 lineup isn’t expected until 2027.
The current plan, based on existing rumors, has Apple announcing the iPhone 18 Pro, iPhone 18 Pro Max, and a new iPhone Ultra in the fall of 2026. The standard iPhone 18 and the more affordable iPhone 18e would then follow in spring 2027. That two-wave release strategy mirrors what Apple did with the iPhone 17 lineup.
What’s clear is that RAM is no longer just a performance number buried in a spec sheet. As AI features become a central selling point for smartphones across the industry, the amount of memory a device has directly determines what it can and can’t do. Apple’s decision to push even the budget models to 9GB suggests the company wants every new iPhone to stay relevant as Apple Intelligence continues to grow.
