Apple’s new iPad Air with M4 comes with a quiet spec change that matters more than it sounds: 12GB of unified memory on the base configuration.
Apple says that’s a 50 percent jump over the previous generation, alongside 120GB/s of memory bandwidth. The starting price stays the same, and the rest of the product is still very “iPad Air,” which makes the memory bump the part worth paying attention to if you use an iPad like a real work device.

RAM is the thing that decides how comfortable your iPad feels after the first week of ownership. Not on day one, when everything is fresh and clean and you’re opening one app at a time. It shows up when your iPad turns into a pile of ongoing tasks: Safari tabs, Notes, a PDF, a call, a couple of messaging apps, and whatever you’re editing or exporting in the background.
That’s why 12GB changes the iPad Air’s sweet spot. The Air has always been powerful enough for most people, and also easy to push into uncomfortable territory once you start multitasking hard. With 12GB, the Air gets more breathing room for the kind of messy, real use that makes iPads feel frustrating: switching between apps every few minutes, dragging files around, bouncing between reference material and writing, or keeping a creative project open while you respond to messages and emails.
Apple also links the memory jump directly to on-device AI performance
The company says M4’s faster Neural Engine, higher memory bandwidth, and bigger unified memory pool help AI models run faster. Even if you ignore the hype words, the practical takeaway is easy: these features only feel useful when they happen quickly and reliably. Apple calls out everyday on-device tasks like searching for subjects and text in photos, and using AI features inside apps such as Goodnotes and Onform: Video Analysis App.
Those experiences benefit when the device has more memory headroom to work with.
The timing matters because iPadOS 26 is leaning hard into workflows that keep more things active at once. Apple is introducing a new windowing system, a new menu bar, and a Files app that’s more capable, including an updated List view, folder customization, folders in the Dock, and the ability to set default apps for specific file types. Apple is also bringing Preview to iPad for viewing, editing, and marking up PDFs and images. All of this pushes the iPad toward heavier multitasking, more file handling, and more “desktop-ish” habits. More memory supports that shift in a very direct way: it reduces the moments where the iPad forgets what you were doing.
This also changes the upgrade math for people on older iPad Air models, especially M1. Apple says iPad Air with M4 is up to 2.3x faster than iPad Air with M1, and up to 30 percent faster than iPad Air with M3. You’ll feel speed gains in plenty of places, especially if you do creative work or gaming.
Apple says the new iPad Air comes in 11-inch and 13-inch sizes, with 128GB, 256GB, 512GB, and 1TB options, and starts at $599 for the 11-inch Wi-Fi model and $799 for the 13-inch Wi-Fi model.
Pre-orders begin Wednesday, March 4, and availability begins Wednesday, March 11.
