Performance & M4 Chip #
- The M4 chip features a 10-core CPU and 10-core GPU, providing a significant boost over the M2 and M3 models.
- Single-core performance is roughly 20-25% faster than the M3, making daily tasks feel snappier.
- Multi-core scores show a 20% improvement, or more, depending on thermal throttling.
- The Neural Engine is 2x faster than previous generations, optimized for "Apple Intelligence" AI features.
Memory & Storage #
- The base model now starts with 16GB of RAM as a standard, moving away from the previous 8GB baseline.
- The device is configurable up to 32GB of RAM for the first time in the Air lineup.
- SSD speeds on the base 256GB model are no longer throttled; it uses dual NAND chips to ensure high read/write speeds.
Display & Design #
- The external chassis remains identical to the M2/M3 redesign: flat, thin, and available in 13-inch and 15-inch sizes.
- The Liquid Retina display now features a "Nano-texture" glass option to significantly reduce reflections and glare.
- SDR brightness has been increased to 500 nits, though it lacks the Pro-motion (120Hz) and Mini-LED technology found in the MacBook Pro.
Connectivity & Ports #
- The M4 Air features two Thunderbolt 4 ports (USB-C), a MagSafe 3 charging port, and a high-impedance headphone jack.
- External display support has improved: it can now drive two external displays even when the laptop lid is open.
- Upgraded wireless connectivity includes support for Wi-Fi 7.
Camera & Audio #
- The front-facing camera is upgraded to a 12MP Center Stage camera.
- "Center Stage" automatically keeps the user centered in the frame during video calls.
- "Desk View" capability allows users to show a top-down view of their workspace.
- The 13-inch model uses a 4-speaker system, while the 15-inch features a 6-speaker system with force-canceling woofers.
Thermals & Battery Life #
- The laptop maintains a fanless, silent design.
- Because there is no fan, the M4 chip will throttle performance under sustained heavy workloads (e.g., long video renders).
- Battery life remains industry-leading, rated for up to 18 hours of web browsing or video playback.
- The 15-inch model offers slightly better thermal dissipation due to its larger surface area.
Summary #
The M4 MacBook Air is a powerful refinement that focuses on future-proofing by making 16GB of RAM the baseline standard. While the physical design remains unchanged, the internal upgrades—specifically the M4 chip, Wi-Fi 7, and the 12MP Center Stage camera—narrow the gap between the Air and the Pro lineups. It is positioned as the best all-around laptop for students and professionals who prioritize portability, silence, and battery life over sustained heavy-duty processing power.
