MacRumors has confirmed that the Apple Watch Series 12 and Apple Watch Ultra 4 have increased RAM compared to previous-generation models. Both new models are equipped with 4GB of RAM, according to Apple's developer tool Xcode 27. Apple Watch Series 11 and Apple Watch Ultra 3 models are equipped with 2GB of RAM, so the Series 12 and Ultra 4 have twice as much memory.

The new models feature a new S11 chip that powers Apple Intelligence features when paired with an iPhone 15 Pro or newer. The increased RAM enables functions like Live Rewind text snippets and Siri Recap summaries, and boosts Siri AI performance. Despite a severe memory chip shortage that has driven up RAM prices and led Apple to raise prices on iPhones, iPads, Macs, and more, the Series 12 and Ultra 4 start at $399 and $799 respectively in the U.S. — the same starting prices as the Series 11 and Ultra 3.

This means consumers get double the memory without a price increase.
