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

The 13-inch MacBook Air with 24GB RAM and 8-core GPU outperforms the 15-inch model’s 10-core GPU in sustained workloads due to lower thermal throttling from its 8W PL1 vs 9W, enabling longer peak performance without fans. Choose the 13-inch 1TB/24GB model if you edit 4K video or run multiple VMs—24GB RAM and 1TB SSD handle large projects without swapping. Opt for the 15-inch 512GB/16GB if you prioritize screen real estate for coding or multitasking across 10+ browser tabs, and its 66.5Wh battery lasts 18 hours on light use. In UAE at AED 6399 vs AED 5799, the 15-inch wins because it’s ₹6000 cheaper and offers 24% larger display; in India at ₹159900 vs ₹144900, the 15-inch wins on value because it delivers 92% of the 13-inch’s performance for 9% less cost.
