Apple MacBook Air 13 (M1, 2020) vs Apple MacBook Air 13 M4 (2025): Full Comparison
Introduction
Comparing the MacBook Air 13 with the M1 chip to the model with the M4 chip illustrates the rapid evolution of Apple’s in-house silicon. This comparison is useful for understanding how core features like processing power, display quality, and machine learning capabilities have progressed over several years. This article will detail the differences and similarities in design, display, performance, battery life, and other key features to help clarify which model might align better with specific user needs.
Design and Build
The fundamental design language of the wedge-shaped, all-aluminum unibody is shared between both models, offering a lightweight and portable form factor. However, the M4 model (2025) typically refines this design with slimmer bezels around the display and potentially new color options. The M1 model (2020) marked the beginning of Apple Silicon in this chassis, and its design is considered a classic iteration of the Air lineage. Both are known for their durability and premium build quality.
Display and Audio
This is one of the most notable areas of improvement. The M1 MacBook Air features a Retina display with a standard LED backlight and support for the P3 wide color gamut. In contrast, the M4 model is expected to upgrade to a Liquid Retina display, which generally offers higher brightness levels and better contrast. Some reports suggest the M4 model may also support ProMotion technology for adaptive refresh rates up to 120Hz, which would make motion appear smoother.
For audio, both laptops feature a stereo speaker system with support for spatial audio and Dolby Atmos. The speaker quality in the M4 model is typically enhanced, offering wider soundstages and clearer audio, which is a common progression with newer generations.
Performance and Chipset
The core of this comparison lies in the system-on-a-chip (SoC).
- M1 Chip (2020): Built on a 5-nanometer process, the 8-core CPU and 7-core or 8-core GPU represented a massive leap in performance and efficiency over Intel-based models at the time. It handles everyday tasks, light photo editing, and moderate multitasking with ease.
- M4 Chip (2025): Built on a more advanced manufacturing process (e.g., 3nm or 2nm), the M4 features a next-generation CPU and GPU with significantly more cores. Its most substantial leap is in its Neural Engine, designed for accelerated machine learning and AI tasks. Performance gains are expected to be substantial across both CPU and GPU workloads.
The M4 is designed to handle more demanding creative applications, complex data analysis, and advanced AI features within macOS and third-party apps.
Battery Life and Connectivity
Both models are renowned for their all-day battery life, a hallmark of the MacBook Air series. Apple typically quotes up to 18 hours of video playback for the M1 model. The M4 model, with its more efficient architecture, may match or slightly exceed this figure under similar usage conditions, though real-world results can vary based on workload.
For connectivity, the M1 Air includes two Thunderbolt / USB 4 ports and a 3.5mm headphone jack. The M4 model is expected to maintain a similar port selection, with the Thunderbolt ports adhering to the latest USB and display standards available at its launch. Both support Wi-Fi 6 and Bluetooth 5.0, with the M4 model likely upgrading to Wi-Fi 6E or Wi-Fi 7.
Camera and Microphone
The M1 MacBook Air is equipped with a 720p FaceTime HD camera. The M4 model features a significant upgrade to a 1080p FaceTime HD camera, which generally provides better image quality in video calls, especially in low-light conditions, thanks to computational photography and the M4’s image signal processor. Both models feature a three-microphone array designed for clear voice pickup, with the M4’s array typically being more advanced for noise reduction.
