It's important to know that this iPad Air M3 13" (Wi-Fi+Cellular) model supports GPS/GNSS, 4G LTE (31 bands), and 5G (26 bands), but not mmWave. This single model is sold globally, except for mainland China, and supports eSIM only, with no physical nano-SIM card slot.
The iPad Air M3 13-Inch (Wi-Fi+Cell) features a fully-laminated, antireflective 12.9" LED-backlit 2732x2048 "Liquid Retina" display (264 ppi, 600 nits) framed by a thin black bezel and housed in a slim aluminum case with rounded corners and flat sides. It is available in (light) Blue, (light) Purple, "Starlight," or "Space Gray."
The iPad Air M3 13" is powered by a 4.05 GHz Apple M3 CPU with 8 cores (4 performance, 4 efficiency), a 9-core GPU, a 16-core Neural Engine, and 8 GB of RAM. Storage options are 128 GB, 256 GB, 512 GB, or 1 TB.
Connectivity includes a USB-C port supporting USB 3 (up to 10 Gb/s), dual-band 802.11ax (Wi-Fi 6E) with 2x2 MIMO, Bluetooth 5.3, and a top-button "Touch ID" sensor. It has a single 12-megapixel "Wide" rear camera (4K video) and a landscape 12-megapixel "Ultra Wide" front camera (1080p video) with "Center Stage." It also has dual landscape stereo speakers and dual microphones.
Battery life is rated at 9 hours on cellular and 10 hours of "surfing the web on Wi-Fi or watching video."
Like its predecessor, this model supports external keyboards, trackpads, and the "Apple Pencil Pro," but was introduced alongside a cheaper, non-backlit "Magic Keyboard" with function keys and a larger trackpad. Compared to its predecessor, the iPad Air M3 13-Inch (Wi-Fi+Cellular) and its siblings are essentially the same except for the faster M3 processor, minor weight variations, and different identifiers.
