Summary
Apple Watch Series 12 and Ultra 4 ship with 4GB of RAM—double the 2GB in the Series 11 and Ultra 3—according to Apple’s Xcode 27 developer tool.
The extra memory supports the new S11 chip’s Apple Intelligence features when paired with an iPhone 15 Pro or newer, including Live Rewind text snippets, Siri Recap summaries and broader Siri AI gains.
Starting prices still hold at $399 for Series 12 and $799 for Ultra 4 in the U.S., matching the prior generation despite the hardware upgrade.
That price stability stands out because a memory-chip shortage has recently pushed up RAM costs and led Apple to raise prices on iPhones, iPads and Macs.
