Apple will equip the iPhone 18 with 12 GB of unified RAM to support a more powerful on-device AI model [1].
This hardware upgrade is critical for the company's AI strategy. By increasing memory, Apple can run complex models locally on the device rather than relying solely on the cloud, which improves processing speed and user privacy.
The announcement came during the WWDC 2026 keynote in San Jose, California [2]. According to reports from South Korea’s KB Securities via DigiTimes, the additional memory is specifically designed to enable smarter Siri features [3]. These enhancements include more expressive Siri voices, and higher accuracy for dictation [1, 2].
Despite the increase in hardware specifications, the base iPhone 18 is expected to maintain a launch price of $799 [4]. This suggests Apple is absorbing the cost of the additional RAM to ensure the base model remains competitive as an AI machine [2]. The iPhone 18 Pro is also expected to keep its starting price at $1,099 [5].
Industry analysts said that this move closes the performance gap between the standard and Pro models. By providing 12 GB of RAM across the lineup, Apple ensures that the most advanced on-device AI capabilities are accessible to a broader range of users — not just those purchasing the most expensive tier [2].
The shift toward larger memory footprints reflects a broader trend in mobile computing where generative AI requires significant resources to operate efficiently. The 12 GB configuration allows the device to handle larger language models while maintaining multitasking stability [1, 3].
“The upcoming iPhone 18 will be equipped with 12 GB of unified RAM”
Apple is pivoting its hardware strategy to prioritize AI readiness over profit margins on individual components. By standardizing higher RAM across the iPhone 18 line without raising prices, the company is positioning the iPhone as a primary AI gateway, ensuring that software-driven features like the new Siri do not suffer from hardware bottlenecks that could alienate users of the base model.
