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

The 15-inch model wins with its 10-core GPU versus the 13-inch’s 8-core GPU, delivering 25% more graphics throughput for video rendering and AI tasks, while both remain fanless with identical thermal design. The 13-inch MacBook Air is best for students and travelers who need 12.5 hours of real-world battery life and 1.225 kg portability for daily commutes or campus use. The 15-inch model suits professionals editing 4K video in Final Cut Pro, where its larger 16.2-inch display and 66.5 Wh battery enable 11.8 hours of continuous playback during multi-track timelines. In UAE at AED 6399 vs AED 7399, the 13-inch is better because it saves AED 1000 with nearly identical CPU and 16GB RAM; in India at ₹159900 vs ₹184900, the 13-inch wins on value because the ₹25000 premium for the 15-inch offers no meaningful performance gain for most workflows.
