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

The Apple MacBook Air 15 M4 wins on CPU performance with its 10-core M4 (4.5 GHz P-cores) versus the M3’s 4.1 GHz P-cores, and its 16 GB LPDDR5-7500 RAM outpaces the M3’s LPDDR5-6400, though both are fanless and thermally identical. The 13-inch M3 model with 512 GB storage and 16 GB RAM suits coders and multitaskers needing faster app launches and more space for local files, while its 1.237 kg weight and 18-hour battery life make it ideal for daily commuters. The 15-inch M4, with its 66.5 Wh battery and 10-core GPU, benefits video editors running 4K timelines in Final Cut Pro, where the larger screen and longer runtime reduce fatigue during extended sessions. In UAE at AED 4299 vs AED 4999, the M3 is better because it offers double the storage for AED 700 less. In India at ₹104900 vs ₹124900, the M3 wins on value because 512 GB storage doubles the usable space without paying ₹20000 extra.
