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

The 13-inch MacBook Air M4 with 24GB RAM and 10-core GPU outperforms the 15-inch model’s 10-core GPU and 16GB RAM in sustained workloads due to higher thermal headroom and dual-channel memory bandwidth, despite identical M4 CPU cores. Buy the 13-inch 1TB/24GB model if you edit 4K video or run multiple VMs—24GB RAM and 1TB SSD prevent bottlenecks during multi-track rendering or Docker containers. Choose the 15-inch 256GB/16GB model if you need a larger 15.3-inch display for coding or presentations and prioritize portability over storage—its 1.52kg weight is still lighter than most 15-inch Windows laptops. In UAE at AED 6399 vs AED 4999, the 15-inch wins because it offers 85% of the performance at 22% lower cost; in India at ₹159900 vs ₹124900, the 15-inch wins on value because ₹35,000 saved buys a 1TB external SSD and still leaves room for accessories.
