MacBook Air M4 vs. M3: A Comprehensive Comparison

MacBook Air M4

Hello, tech enthusiasts! Editor Z from AITech blogZ here. Apple has officially launched the MacBook Air M4 on March 6, 2025, as the successor to the M3 model. With notable enhancements in performance, memory, and AI capabilities, the M4 offers a compelling upgrade. Let's break down the differences to help you decide which model suits your needs best.

Release Timeline & Availability As of March 6, 2025, the MacBook Air M4 has replaced the M3 on Apple's official website. While some retailers may still have M3 stock available, its availability is expected to decrease over time.

Performance and Processing Power The MacBook Air M4 is powered by Apple's latest M4 chip, featuring a 10-core CPU (4 performance cores, 6 efficiency cores) and a 10-core GPU. This marks a step up from the M3, which had an 8-core CPU (4 performance cores, 4 efficiency cores) and a 10-core GPU. Additionally, the M4 model supports up to 32GB of unified memory, whereas the M3 was limited to 24GB. The increased core count and memory bandwidth (120GBps vs. 100GBps on the M3) ensure superior multitasking and overall efficiency.

AI & Neural Processing One of the most significant upgrades in the M4 model is its enhanced AI capabilities, powered by Apple Intelligence. Unlike the M3, the M4 is optimized for AI-driven tasks such as image generation, real-time speech processing, and advanced computational photography, making it a better choice for professionals relying on AI workflows.

Display and Graphics Both models feature a Liquid Retina display with similar brightness and resolution. However, the M4 introduces ProMotion technology, offering a 120Hz variable refresh rate for smoother animations, gaming, and video editing. The M3, on the other hand, is limited to a 60Hz refresh rate.

Battery Life & Charging Both the M3 and M4 claim up to 18 hours of battery life, with fast charging capabilities (50% charge in 30 minutes). The real-world battery performance may slightly favor the M4 due to its more power-efficient architecture.

Connectivity & Ports Both models feature Thunderbolt 4 ports and a 3.5mm headphone jack. However, the M4 supports Wi-Fi 6E, providing improved wireless speeds and lower latency compared to the M3’s Wi-Fi 6.

Design & Color Options Apple has maintained its signature thin and lightweight design for both models. However, the M4 introduces a new Sky Blue color, adding to the existing Silver, Starlight, and Midnight options.

Pricing & Value Surprisingly, the M4 models have launched at a lower price point than their predecessors:

  • MacBook Air M4 13-inch: Starts at $999 (vs. M3’s $1,099)
  • MacBook Air M4 15-inch: Starts at $1,199 (vs. M3’s $1,299) This pricing strategy makes the M4 a more attractive option for those looking for better performance at a reduced cost.

Conclusion The MacBook Air M4 offers meaningful upgrades over the M3, including a stronger CPU/GPU, more RAM capacity, AI optimization, and ProMotion display technology. Given its lower launch price and improved specs, the M4 is the superior choice for most users. However, if you already own an M3 and do not require AI-driven features, an upgrade may not be immediately necessary.
