Verdict: The M3 is ~20% faster in CPU tasks and ~30% better in GPU workloads than the M2. However, real-world differences are smaller for basic tasks like web browsing.
Thermal Performance (No Fan, Still Cool?)
-
M3 runs cooler than M2 under sustained load (3nm efficiency helps)
-
No throttling in 30-minute stress test (vs slight throttling on M2)
-
Best for writers, students, light editing – not hardcore video editing

| Usage Scenario | M3 MacBook Air | M2 MacBook Air |
|---|---|---|
| Web Browsing (50% brightness) | 16h 45m | 15h 30m |
| Video Playback (Local 1080p) | 18h 20m | 17h 10m |
| Light Photo Editing | 10h 15m | 9h 40m |
| Gaming (Baldur’s Gate 3, Low Settings) | 4h 50m | 4h 10m |
Verdict: ~1-1.5 hours more battery life than M2, thanks to 3nm efficiency.
Should You Upgrade? (Who Is It For?)
✅ Worth Upgrading If…
✔ You’re coming from Intel MacBook or M1 Air
✔ You need dual external display support
✔ You want better GPU performance for light gaming
✔ You’re a student or professional needing max portability
❌ Not Worth It If…
✖ You already own an M2 MacBook Air (minor gains)
