MacBook Air 13 (M3) vs MacBook Air 15 (M4)

The M4’s 10-core CPU with 4.5 GHz P-cores outperforms the M3’s 4.1 GHz P-cores, and its 10-core GPU with higher memory bandwidth (LPDDR5-7500 vs. LPDDR5-6400) delivers faster sustained workloads—both are fanless, but the M4 handles prolonged tasks more efficiently. Choose the 13-inch M3 with 24GB RAM and 1TB storage if you edit 4K video or run multiple VMs, as the extra RAM and storage reduce swap usage and improve export times. Opt for the 15-inch M4 if you prioritize screen real estate for coding or multitasking across 10+ browser tabs, benefiting from the larger 340.4mm display and 66.5Wh battery that lasts 18+ hours in light use. In UAE at AED 5899 vs. AED 4999, the M4 wins because it’s 15% cheaper and faster; in India at ₹144900 vs. ₹124900, the M4 wins on value because it delivers 20% more CPU performance for ₹20,000 less.
