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

The Apple MacBook Air 13 M4 Entry wins on CPU performance with its 10-core M4 (4×4.5 GHz P-cores, 6×2.9 GHz E-cores) versus the M3’s 8-core (4×4.1 GHz P-cores, 4×2.7 GHz E-cores), and its 24GB RAM exceeds the M3’s 16GB, enabling smoother multitasking without thermal throttling since both are fanless. Choose the M4 model if you edit 4K video or run multiple virtual machines—24GB RAM and 1TB storage handle large files and apps without slowdowns. The M3 15-inch suits those needing more screen real estate for coding or spreadsheets—its 15.5-inch display (340.4mm wide) and 66.5Wh battery deliver 18+ hours of web browsing, outweighing the 13-inch’s 11.97-inch screen and 53.8Wh battery. In UAE at AED 6399 vs AED 5299, the M3 wins on value because it offers 88% of the M4’s performance at 83% of the price; in India at ₹159900 vs ₹129900, the M3 wins on value because the 30% price gap justifies the 15% performance gap for most workflows.
