MacBook Air M3 vs MacBook Air M4

The MacBook Air M4 offers notably better CPU performance with a 10-core processor versus M3's 8-core, plus 16GB base RAM and improved efficiency, making it worth the $250-$300 premium for most users. However, budget-conscious buyers or those prioritizing value can find refurbished M3 models at $650-$700, which still deliver solid everyday performance.
