Notable improvements over M2: better battery efficiency from improved 3nm fabrication, ProMotion 120Hz displays render LDB UI more smoothly, and the wider Pro/Max GPUs benefit Monitor's video encoding.

Frequently asked questions
Is M3 noticeably better than M2 for LDB?
Marginally - ~10-15% better battery and slightly lower CPU. Both handle LDB comfortably. The bigger upgrade reasons are general (battery on Air, performance on Pro/Max).
Should I prefer M3 over M4 for a new Mac purchase in 2026?
M4 is current generation as of 2024-2025. M3 is on extended availability via refurbished. M4 is the better long-term choice; M3 is a solid value if pricing is meaningfully lower.
