MacBook Air M4 vs MacBook Air M5
MacBook Air M4 (2025)
Apple's previous-gen 10-core laptop with 8-core GPU and Wi-Fi 6E starting at $999 with 256GB storage.
Budget-conscious buyers who already own one (no upgrade needed), students, and light users prioritizing cost over storage.
MacBook Air M5 2026
Ultraportable laptop with M5 chip delivering excellent everyday performance at an accessible price point.
New MacBook buyers, AI/ML developers, content creators, and professionals who value future-proofing and doubled base storage.
Short Answer
The M5 offers 4x faster LLM processing, Wi-Fi 7, and double the base storage (512GB vs 256GB) for just $100 more, making it the better value for new buyers. However, M4 owners will see negligible real-world performance differences in daily use, making an upgrade unnecessary.
Our Verdict
AI-assistedChoose the MacBook Air M4 if you already own one—the real-world performance gain doesn't justify the upgrade cost, and daily business tasks run identically. Choose the M5 if you're a new buyer—the $100 premium is justified by doubling base storage to 512GB, gaining Wi-Fi 7, and future-proofing with 4x faster AI/LLM capabilities.
