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

Both MacBook Air models share the identical Apple M4 10-core CPU and 10-core GPU, so performance is identical—no thermal advantage or disadvantage exists since both are fanless. The 256GB model suits students and office workers who store files云端 and use light apps, benefiting from 16GB RAM and 12.5 hours of video playback. The 512GB model is better for photographers editing 4K RAW files or developers running Docker containers, where 512GB storage reduces swap usage and speeds up project loads. In UAE at AED 4999 vs AED 5799, the 256GB model is better because it saves AED 800 with no performance loss; in India at ₹124900 vs ₹144900, the 256GB model wins on value because the ₹20,000 price gap doesn’t justify extra storage for most users.
