Moore’s Law

Moore’s Law is the semiconductor scaling frame discussed in EP270 一枚芯片的漫长征途：我们离“算力自由”还有多远？. The episode traces it to Gordon Moore in the 1960s, first as an observation about component counts on integrated circuits and later as an industry rhythm often summarized as doubling roughly every 18 to 24 months.

The source treats Moore’s Law as both technology and coordination. Regular density gains improved performance and reduced cost, making chips cheap enough for ordinary devices. But as process nodes approach physical and economic limits, the industry increasingly looks to architecture, advanced packaging, and system-level design rather than relying on simple shrinkage.

华为的「韬定律」，是创新还是噱头？｜ Bonus adds Tau Law as a proposed post-Moore metric. The source does not say Tau Law has already replaced Moore’s Law; it treats Huawei’s “equivalent 1.4 nm by 2031” language as a system-performance comparison whose credibility depends on Cell-to-Cell Logic Stacking, EDA, packaging, and measured production results.

真正改变世界的技术，为什么一开始都不被看好？| S10E16 adds the commercial origin story. 汪波 says early integrated circuits were hard to sell because customers preferred cheaper discrete transistor assembly, so Moore’s forecast also worked as a roadmap and confidence device for a young industry. The episode emphasizes that early objections around yield, heat, and missing EDA were real, which makes Moore’s Law a case of coordinated industry belief rather than inevitability.

Key Claims

• Moore’s Law helped organize semiconductor investment, roadmaps, and expectations, not just describe a neutral trend.
• Smaller process nodes can improve performance and cost, but below roughly two nanometers the episode highlights leakage, quantum effects, and difficult transistor structures.
• Leading-edge fabs now require enormous capital spending, so continuing process scaling has a weaker cost-benefit profile than in earlier eras.
• Post-Moore progress can come from packaging, memory proximity, architecture, and software-hardware co-design.
• Tau Law is one proposed post-Moore framing, but the What’s Next source keeps it at the level of a plausible metric until the hardest implementation claims are proven.
• S10E16 adds that law-like semiconductor forecasts can operate as coordination devices before the tooling and manufacturing proof is complete.
