The Day the Clock Stopped
Comments on “The Day the Clock Stopped”
Claim-checked. Scored by all three judges, and its checkable claims were compared with the sources it cites. How far stories are checked
Intel's clock speed rose almost sixtyfold from 1993 to 2004, then barely doubled in the following twenty years. The article argues this stall came from Dennard scaling breaking down, not Moore's Law ending: supply voltage stopped falling, so shrinking transistors began generating too much heat and leakage.
Why it ranked
No. 122 of 155 with a score of 0.57. The panel rated it highest on new information (0.91) and technical depth (0.83), lowest on practical relevance (0.56). The claim check took 0.100 off.
- AI judgeJudge 2claude-haiku-5-5
- Well-sourced, technically deep history of the memory wall and multicore shift with AI-chip relevance; a long-form series part with limited immediate actionability, though it is substantive and new relative to recent stories.
- AI judgeJudge 3gpt-5.6-luna
- A deeply researched historical and architectural analysis connects Dennard scaling, memory latency, Sun’s Niagara, and today’s AI-chip economics. It is highly relevant and technically useful, though some conclusions about current AI winners are interpretive and partly future-facing.
