iPhone RAM Comparison
Apple doesn't advertise RAM on its spec sheets, but teardowns and developer documentation confirm the exact amounts. RAM matters for multitasking, keeping apps alive in the background, and running on-device AI features like Apple Intelligence (which requires a minimum of 8 GB).
Models highlighted in green meet the 8 GB threshold for Apple Intelligence support.

Why RAM Matters for iPhones
Unlike Android phones where manufacturers prominently advertise RAM, Apple keeps this specification off its marketing materials. However, RAM has become increasingly important since iOS 18 introduced Apple Intelligence — a suite of on-device AI features that require a minimum of 8 GB to function. This means the iPhone 14 and earlier models (with 6 GB or less) are permanently locked out of features like Writing Tools, Image Playground, and Genmoji, regardless of which iOS version they run.
For practical purposes, 8 GB provides smooth multitasking with 10-15 apps in memory. The 12 GB in Pro Max models allows heavier workflows like editing 4K ProRes video while keeping reference apps open. If you plan to keep your iPhone for 4+ years, buying a model with at least 8 GB ensures you won't miss out on future AI features.
