摩尔定律放缓对手机意味着什么

Moore’s Law predicted transistor counts on chips would double every two years — a trend that held strongly from 1970 to 2010.
Since then, shrinking transistors further has caused overheating, power leakage, and diminishing performance gains per nanometer.
Chipmakers now rely less on raw size reduction and more on architectural innovations like chiplets and heterogeneous cores.
Smartphones now improve through better software optimization, AI-enhanced cameras, and advanced thermal management — not just faster CPUs.
Battery life matters more than peak speed, so engineers prioritize efficiency: doing more with fewer watts, not just more transistors.
Camera quality jumped not from bigger sensors alone, but from neural processing units that sharpen images in real time using learned patterns.
Instead of waiting for ‘next-gen’ chips, brands extend device lifespans via longer software support and modular repair designs.
Slower scaling also pushes innovation toward specialized hardware — like dedicated AI engines — rather than general-purpose speed boosts.
Consumers notice subtler upgrades: smoother multitasking, better low-light photos, or longer battery between charges — not just benchmark scores.
While Moore’s Law fades as a strict rule, its spirit lives on — engineers keep delivering real-world improvements, just differently.
