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

The 15-inch model wins on GPU performance with a 10-core Apple M4 GPU versus the 13-inch’s 8-core GPU, and sustains 9W PL1 vs 8W, enabling slightly longer sustained workloads without thermal throttling in both fanless designs. The 13-inch model is best for students and mobile professionals needing all-day battery life—up to 18 hours of video playback—and portability under 1.23 kg for daily commutes. The 15-inch model suits creatives editing 4K video or running multiple apps simultaneously, thanks to its 66.5 Wh battery (22+ hours playback) and larger 340.4 x 237.6 mm screen for multitasking. In UAE at AED 3999 vs AED 4999, the 13-inch is better because it saves AED 1000 with near-identical CPU and RAM for 90% of tasks. In India at ₹99900 vs ₹124900, the 13-inch wins on value because ₹25000 less delivers the same M4 chip and 16GB RAM without sacrificing core functionality.
