The Apple MacBook Air "M3" 8-Core CPU/8-Core GPU 13-Inch (2024) model features a 4.05 GHz Apple M3 processor with 8 cores (4 performance cores and 4 efficiency cores), an 8-core GPU, a 16-core Neural Engine, 8 GB or 16 GB of "unified" default onboard RAM (8 GB from March 4, 2024 until October 30, 2024 and 16 GB afterwards), and a 256 GB onboard SSD. Both the RAM and the SSD could be configured with higher capacities at the time of initial system purchase (which also automatically upgrades the integrated GPU to one with 10-cores), but neither the RAM nor the SSD can be upgraded subsequently.

This all is tucked in a uniformly thin aluminium case with an integrated 1080p "FaceTime HD" webcam, a four-speaker sound system, Touch ID, a backlit "Magic Keyboard", a large "Force Touch" trackpad, and a high-resolution 13.6" LED-backlit 2560x1664 (224 ppi, 500 nits) "Liquid Retina" display with Wide colour (P3) and True Tone technology.

The aluminium case is available in four colour options -- dark blue "Midnight" (pictured, left), a warm grey "Starlight", a darker "Space Grey", and classic silver. It weighs 2.7 pounds (1.24 kg). Apple estimates battery life at 15-18 hours, depending on the task performed. By default, it shipped with a MagSafe 3-equipped 30W USB-C power adapter. However, for an extra US$20, it could be configured with a 35W Dual USB-C Port Compact Power Adapter or a fast-charge 70W USB-C Power Adapter.

Connectivity includes 802.11ax Wi-Fi 6E, Bluetooth 5.3, two Thunderbolt 3/USB 4 ports (USB-C connector), and a 3.5 mm headphone jack.

Compared to its M2 predecessors, the MacBook Air "M3" models use the same housing but have a faster architecture, increased external display support, faster Wi-Fi, and microphone improvements. The dark blue "Midnight" color option has a new "anodization seal to reduce fingerprints" as well.
