Understanding Moore’s Law and the Slowing Pace of Chip Advancements
– Moore’s Law states that the number of transistors on chips doubles every 2 years, driving exponential growth in computing power. This held true from the 1960s to the early 2000s.
– However, the pace of advancement has slowed recently due to technical challenges in manufacturing smaller transistors near-atomic scale.
– Key challenges include quantum effects, overheating, power consumption, and lithography costs. This has pushed the doubling time to 2.5-3 years.
– While chip technology continues to advance, diminishing returns on Moore’s Law have shifted focus to innovations in architecture, software, specialized AI chips, 3D stacking, and new materials like graphene.
– Maintaining pace will require new computing paradigms and billions in R&D investments. Nations are prioritizing chip technology leadership.
