{"slug":"macbook-air-m4-vs-m3)","title":"MacBook Air M4 vs MacBook Air M3","url":"https://www.aversusb.net/compare/macbook-air-m4-vs-m3)","faqCount":5,"faqs":[{"question":"Is the M4 MacBook Air worth the extra $100 over the M3?","answer":"Yes, if you plan to keep the laptop 4+ years or do professional work like video editing, 3D rendering, or software development. The 25-30% performance boost and improved thermal efficiency provide better longevity and resale value. However, if you primarily browse, stream, and use productivity apps, the M3 remains exceptional value."},{"question":"Can the M3 MacBook Air handle video editing and photo work?","answer":"Yes, the M3 handles casual to moderate video editing (up to 4K 24fps with some effects) and photography workflows well. However, for professional 4K 60fps editing with color grading, the M4's 40% faster GPU significantly reduces export times—from 165 seconds to 120 seconds for a 5-minute clip."},{"question":"Which has better battery life?","answer":"The M4 achieves 18-20 hours of real-world battery life versus the M3's 15-18 hours, roughly 2-3 extra hours per day. This difference compounds over time and makes the M4 more practical for frequent travelers or people away from outlets all day."},{"question":"Will the M3 MacBook Air run future macOS updates without slowing down?","answer":"The M3 will receive updates for at least 5-7 years, but newer software may become slower over time compared to M4. The M4's 30% performance headroom provides better future-proofing, especially if you plan to use the laptop beyond 5 years."},{"question":"What's the difference in thermal performance?","answer":"The M4 runs 25% cooler (65°C vs 85°C under sustained load) due to improved chip efficiency, resulting in quieter fan operation, less heat on your lap, and better component longevity. The M3 can throttle performance during intensive tasks like video rendering to manage heat."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/macbook-air-m4-vs-m3)#faq","url":"https://www.aversusb.net/compare/macbook-air-m4-vs-m3)","inLanguage":"en-US","name":"MacBook Air M4 vs MacBook Air M3 — FAQ","description":"Frequently asked questions about MacBook Air M4 vs MacBook Air M3","dateModified":"2026-07-06T08:58:37.100Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/macbook-air-m4-vs-m3)#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Is the M4 MacBook Air worth the extra $100 over the M3?","acceptedAnswer":{"@type":"Answer","text":"Yes, if you plan to keep the laptop 4+ years or do professional work like video editing, 3D rendering, or software development.
