Apple Watch Series 12 and Ultra 4 Have a Hidden Upgrade

MacRumors has confirmed that the Apple Watch Series 12 and Apple Watch Ultra 4 have increased RAM compared to the 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.

Apple Watch Series 12 and Apple Watch Ultra 4 models are equipped with a new S11 chip that powers new Apple Intelligence features when the watches are paired to an iPhone 15 Pro or newer. The increased RAM will help to enable these new functions, such as Live Rewind text snippets and Siri Recap summaries, and give a boost to Siri AI.

Despite a severe memory chip shortage that has driven up the price of RAM and resulted in Apple raising prices on iPhones, iPads, Macs, and more in recent months, the Series 12 and Ultra 4 start at $399 and $799 respectively in the U.S., meaning the devices have the same starting prices as the Series 11 and Ultra 3 even with more RAM.
