Apple MacBook Air 15" M3 vs Apple MacBook Pro 14" M4
Side-by-side specifications, scores and verdict.
Quick Verdict
Apple's M3 Air offers excellent value at $1299 with its spacious 15-inch display and reliable performance for everyday tasks, but the 256GB storage and 8GB RAM feel constraining for the price point. Meanwhile, the 14-inch M4 Pro commands a $300 premium with substantially more muscle: faster M4 chip, doubled base storage to 512GB, 16GB RAM standard, and a superior mini-LED XDR display hitting 1600 nits versus 500. Battery life stretches to 24 hours on the Pro versus 18 on the Air. Port connectivity heavily favors the Pro with HDMI, SD card, and three Thunderbolt ports compared to the Air's two. The Pro's 120Hz ProMotion display and brighter output suit creative professionals and demanding workflows. For casual users prioritizing screen real estate and basic productivity, the Air 15 remains compelling. However, the Pro 14 delivers meaningfully better specs across nearly every dimension—processor, RAM, storage, display quality, and connectivity—justifying its premium. Choose the Air for budget-conscious buyers; invest in the Pro for professional work or longevity.
