Apple MacBook Air 13" M3 vs Apple MacBook Air 13" M4

Both MacBook Air 13" models share identical pricing at $1099, yet the M4 variant delivers substantially better value through generational improvements. Display quality remains consistent with 2560x1664 Liquid Retina panels, 500-nit brightness, and 60Hz refresh rates across both systems. Battery life claims match at 18 hours for typical wireless workflows. Critical differentiation emerges in processing power: the M4 features a 10-core CPU and GPU configuration versus the M3's 8-core setup, alongside double the standard RAM (16GB vs 8GB). Storage configurations diverge meaningfully—the M4 offers upgradeable storage up to 2TB, while the M3 caps at 256GB without expansion options. Both maintain excellent portability at 1.24kg with aluminum construction and dual Thunderbolt ports. For everyday productivity, content creation, and future-proofing, the M4 represents the superior choice at identical cost, offering meaningful performance gains and superior upgrade pathways that justify selection despite marginal generational jumps.
