MacBook 12 (2015) vs MacBook Air 13 (2017)

The MacBook Air 13.3" (2017) wins with its Intel Core i5-5350U (1.8–2.9 GHz) versus the MacBook 12’s Core M-5Y31 (0.9–2.4 GHz), delivering 38% higher peak clock speed and better thermal headroom since it has a fan. The MacBook 12 (920 g, fanless) suits travelers needing ultra-light portability for light web browsing and document work, with 512GB storage and 8GB RAM handling basic multitasking without overheating. The MacBook Air (1.35 kg, with fan) is better for coders and light video editors: its dual USB 3.0 ports, SD card reader, and 54 Wh battery (up to 12 hours real-world use) support external drives and extended sessions. In UAE at AED 799 vs AED 899, the MacBook 12 is better because it offers 512GB storage for the same price as the Air’s 256GB. In India at ₹18900 vs ₹18900, the Air wins on value because its SD reader and dual USB ports add utility the fanless model lacks.
