Comparison of MacBook Air M3 and MacBook Air M2: Performance
One of the key points to compare between MacBook Air M3 and MacBook Air M2 is the processors of the two products. Specifically, MacBook Air M3 uses the Apple M3 chip (released in 2023), while MacBook Air M2 uses the Apple M2 processor (released in 2022). Before diving into details, let's go through some specifications of MacBook Air M3 and MacBook Air M2 for you to grasp easily.
- MacBook Air M3:
- Display: 13.6-inch size, Liquid Retina panel, 2,560 x 1,664 pixels resolution, 500 nits brightness.
- CPU: Apple M3 8-core (4 high-performance cores + 4 energy-efficient cores).
- GPU: 8-core or 10-core.
- RAM: Minimum of 8 GB and maximum of 24 GB.
- SSD Storage: Minimum of 256 GB and maximum of 2 TB.
- Operating System: MacOS 14 Sonoma.
- Battery: Up to 18 hours (as per Apple's claim).

- MacBook Air M2:
- Display: 13.6-inch size, Liquid Retina panel, 2,560 x 1,664 pixels resolution, 500 nits brightness.
- CPU: Apple M2 8-core (4 high-performance cores + 4 energy-efficient cores).
- GPU: 8-core or 10-core.
- RAM: Minimum of 8 GB and maximum of 24 GB.
- SSD Storage: Minimum of 256 GB and maximum of 2 TB.
- Operating System: MacOS 13 Ventura (can be upgraded to MacOS 14 Sonoma).
- Battery: Up to 18 hours (as per Apple's claim).

According to Apple's announcement, the Apple M3 chip in the new generation MacBook Air delivers over 20% superior performance compared to the Apple M2 chip, thanks to improvements in both CPU and GPU. Moreover, the Apple M3 is the first generation of Apple Silicon chip to feature Ray Tracing cores in the GPU, combined with new-generation AI algorithms in the Neutral Engine cores to provide realistic imagery for gaming or image/video processing.
To compare the performance between MacBook Air M3 and MacBook Air M2, I've referred to some benchmark tests using dedicated scoring software conducted by the Max Tech YouTube channel. You can also find more detailed information in the article comparing the Apple M3 and Apple M2 chips that I've conducted.
- GeekBench 6 (single-core/multi-core):
- MacBook Air M3: 3,093 points/11,997 points.
- MacBook Air M2: 2,621 points/9,968 points.

- Cinebench 2024:
- MacBook Air M3: 549 points.
- MacBook Air M2: 485 points.

- 3DMark Wild Life Extreme (average frame rate):
- MacBook Air M3: 42 FPS.
- MacBook Air M2: 34.2 FPS.

Thus, the performance provided by Apple M3 for MacBook Air M3 is significantly superior or slightly better in some tests compared to Apple M2. Additionally, The Tech Chap YouTube channel has compared real-world tasks using graphics applications and gaming on MacBook Air M3 and M2, with specific results as follows.

Overall, the results from performance scoring as well as real-world usage on MacBook Air M3 are significantly superior to MacBook Air M2. This could be a result of leveraging the new 3nm process and utilizing more GPU cores on the Apple M3 chip, enabling the device to handle tasks more optimally than the Apple M2.
Comparison of MacBook Air M3 and MacBook Air M2: Battery Life
According to Apple's announcement, both MacBook Air M3 and MacBook Air M2 are equipped with batteries that provide users with equivalent durations of 18 hours for continuous video playback and 15 hours for continuous web browsing over Wi-Fi. However, these are laboratory-based claims, so the actual battery life of the devices depends heavily on real-world conditions.

In a performance comparison video between MacBook Air M3 and MacBook Air M2, reviewer Max Tech mentioned that after a series of tests and heavy usage experiences, there was a significant difference in the remaining battery percentage between the two devices. Specifically, MacBook Air M3 still had 34% battery left, whereas the MacBook Air M2 model only had 21% battery remaining.

Hence, this could well be evidence that the Apple M3 chip on the new MacBook Air has been significantly optimized for power efficiency, helping to prolong usage time to cater to longer work and entertainment needs.
Comparison between MacBook Air M3 and MacBook Air M2: Design, Connectivity Ports
In terms of appearance, there is hardly any change in the overall design style and dimensions between MacBook Air M3 and MacBook Air M2. Specifically, the products are crafted from sturdy aluminum frames with compact dimensions, accompanied by meticulously finished edge details and corners, all without any unnecessary elements.

The surfaces of both MacBook Air M3 and MacBook Air M2 are still lightly textured, which can somewhat mitigate the issue of sweat and fingerprint marks during usage. Additionally, both generations of MacBook Air come in 4 color options: Midnight (Dark Blue), Starlight (Gold), Space Gray, and Silver.

Moreover, both MacBook Air M3 and MacBook Air M2 feature the same number of connectivity ports, including a 3.5mm audio jack and on the left edge, a MagSafe charging port, and 2 USB-C ports. Particularly, the standout feature of the MacBook Air M3 lies in its ability to drive two displays simultaneously from two USB-C ports (while the device is closed), instead of just one display in the previous generation.

Enabling dual-screen output on the MacBook Air M3 is truly impressive in terms of functionality, but it still has some limitations. Specifically, to output images to two displays simultaneously, users need to close the laptop, which can be quite inconvenient. Moreover, the performance will be reduced by about half when using this feature, as shared by Max Tech.
Comparison of MacBook Air M3 and MacBook Air M2: Display, Keyboard, Trackpad
In terms of display, both MacBook Air M3 and MacBook Air M2 are equipped with a 13.3-inch widescreen display, with a resolution of 2560 x 1664 pixels, using Liquid Retina panel with high brightness capable of reproducing images realistically and sharply. In the case of the MacBook Air M3, the device also has a 15.3-inch widescreen version with a resolution of 2880 x 1864 pixels, providing a larger display space and suitable for various tasks.

Furthermore, both the MacBook Air M3 and MacBook Air M2 are equipped with the Magic Keyboard layout, covering 75% of the keyboard area. According to YouTuber The Tech Chap, this keyboard section still provides a good typing experience, with consistent key travel and just the right amount of key bounce. Additionally, the TrackPad of both devices is generously sized for comfortable operation.

In terms of audio, both the MacBook Air M3 and MacBook Air M3 are equipped with a 4-speaker system, supporting Spatial Audio when playing music or videos with Dolby Atmos, and supporting head tracking with AirPods 3, AirPods Pro, and AirPods Max. Additionally, the speakers of both devices are subtly concealed, so users may not always notice them.
Conclusion
MacBook Air is designed by Apple to meet basic needs such as office work, web browsing, light graphics, etc., so I believe that the performance of both MacBook Air M3 and MacBook Air M2 is still extremely good and does not significantly affect the user experience. At the current time, the MacBook Air M2 still has the capability to handle the mentioned tasks with ease, so you can also choose to optimize costs.

The above are comparisons of MacBook Air M3 and MacBook Air M2 - the two lightest MacBook products from Apple at the moment. What do you think about this laptop duo? What will be your choice?
