Performance: A Generational Leap (and Surprising Consistency)
The core of any MacBook Air lies in its Apple Silicon chip. While each generation brings advancements, the real-world impact varies depending on your workload.
CPU Performance:
Benchmarking tools like Cinebench 2024 and Geekbench 6 reveal a clear, albeit incremental, performance uplift with each new chip in single-core tasks. The M2 outpaces the M1 by 9%, the M3 bests the M2 by 17%, and the M4 leads the M3 by 21%. For everyday tasks like web browsing, document creation, and email management, these differences are largely imperceptible. All MacBook Air models maintain a snappy feel, even the M1.
However, for demanding workloads such as programming, 3D rendering, or intensive photo and video editing, the M4’s beefier 10-core CPU (featuring two extra efficiency cores compared to the M1, M2, and M3’s 8-core setup) demonstrates a substantial lead in multi-core performance. This advantage is particularly evident in applications like Premier Pro and DaVinci Resolve, which handle 4K and 8K media files.
GPU Performance:
The base M2, M3, and M4 chips feature an 8-core GPU, an upgrade from the M1’s 7-core GPU. This gives the M1 a noticeable disadvantage in GPU-intensive tasks. While the M2, M3, and M4 are closely matched in basic GPU computations, the M3 and M4’s redesigned GPU architecture, with hardware-accelerated ray tracing, truly shines in applications requiring complex shading and rendering. For instance, the M3 Air rendered a Blender animation 25% faster than the M2, while the M4 Air was 10% faster than the M3. Even in AAA gaming titles like Resident Evil 4, the M4 delivers smoother gameplay and higher frame rates.
Thermals and Power Efficiency:
Both the M3 and M4 chips utilize TSMC’s 3nm process, a step up from the 5nm M1 and M2. The M4, specifically, benefits from TSMC’s enhanced N3 process, offering superior efficiency. Testing shows the M4 Air consistently maintaining lower CPU temperatures and consuming less power than the M3 Air under load, highlighting its impressive engineering. While all Air models rely on passive cooling and can get warm under sustained heavy loads, this is rarely an issue for typical use.
Neural Engine (AI Performance):
The M4 boasts a significantly faster neural engine, claiming to be over two times quicker than the M3 and three times faster than the M1. While benchmarks like Geekbench AI confirm this generational gap, real-world AI applications, such as running local AI models, show less dramatic differences, suggesting that while the hardware is capable, software optimization plays a crucial role.

Design and Features: Iterative Refinements
The design language of the MacBook Air underwent a significant overhaul with the M2, moving away from the classic tapered look of the M1 to a more uniform, flat chassis. The M2, M3, and M4 generations share this modern aesthetic.
External Display Support:
A major upgrade on the M4 Air is the inclusion of two Thunderbolt 4 ports, replacing the older Thunderbolt 3 standard. This allows the M4 to support up to two 6K 60Hz external displays simultaneously, even with the laptop lid open. The M3 Air can also connect to two external monitors, but only if its lid is closed – a rather peculiar limitation. The M1 and M2 Airs are limited to a single external display.
Webcam:
Starting with the M2, Apple introduced a sharper 1080p webcam. The M4 Air further enhances this with “Center Stage,” which keeps you in the frame as you move, and “Desk View,” allowing for an overhead view of your desk during video calls.
Keyboard and Trackpad:
Apple’s Magic Keyboard and spacious haptic trackpad remain industry benchmarks across all models, offering an exceptional typing and navigation experience. The M2, M3, and M4 models feature full-height function keys, a minor ergonomic refinement over the M1.
Speakers:
The M2 Air brought improved speakers with enhanced loudness and clarity compared to the M1. However, the M3 and M4 Airs retain the same four-speaker sound system as the M2, indicating no further advancements in this area.
Display:
All M2, M3, and M4 MacBook Airs feature a 13-inch IPS display with slimmer bezels, a webcam notch, and a brightness boost to 500 nits (up from the M1’s 400 nits). All four generations offer near-perfect color accuracy, covering 100% sRGB and almost 100% P3 color gamut, making them suitable for color-sensitive work.

Battery Life: Consistent Endurance
Despite variations in battery size (M1 having the smallest, M4 the largest), Apple rates all MacBook Air models for up to 15 hours of wireless web browsing. Real-world testing reveals that the M2, M3, and M4 models offer very similar endurance, losing around 13% charge during a local 4K video playback test. The M1, being an older unit in testing, showed slightly more degradation. Realistically, expect 10-12 hours of light everyday use from any of these models on a full charge with a healthy battery. The included 30W charger takes approximately 2.5 hours for a full recharge.
