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

The M4’s 10-core CPU with 4.5 GHz P-cores and 7500 MT/s RAM outperforms the M3’s 4.1 GHz P-cores and 6400 MT/s RAM, delivering 15–20% faster sustained workloads despite lower PL1 power. Buy the M3 512GB model if you edit 4K video or store large files—16GB RAM handles multitasking, and 512GB storage avoids constant cloud reliance. Choose the M4 256GB if you prioritize faster app launches, AI tasks, or future-proofing—its 10-core GPU and LPDDR5-7500 boost machine learning speed by 22% in benchmarks. In UAE at AED 5299 vs AED 4999, the M4 wins because it’s ₹5000 cheaper in India while offering a newer chip and macOS 15, making its storage deficit acceptable for non-media creators.
