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

The Apple MacBook Air 15 M4 512GB/16GB wins on CPU performance with its 10-core M4 (4.5 GHz P-cores, 2.9 GHz E-cores) versus the M3’s 8-core (4.1 GHz P-cores, 2.7 GHz E-cores), delivering 15–20% faster multi-threaded output and 10% higher GPU bandwidth. The M3 model suits students and office workers who need all-day battery life (up to 18 hours video playback) and lower heat, as its 12W sustained power draw keeps the fanless design silent under light loads. The M4 model is for professionals editing 4K video in Final Cut Pro or running AI tools, where its LPDDR5-7500 RAM and 10-core GPU handle 12-bit ProRes timelines 22% faster than the M3. In UAE at AED 5299 vs AED 5799, the M3 is better because it saves AED 500 with near-identical battery and portability; in India at ₹129900 vs ₹144900, the M3 wins on value because ₹15000 saved offsets minimal performance gains for most users.
