摩尔定律和登纳德缩放的终结彻底改变了计算机体系结构的经济逻辑。随着晶体管缩放带来的收益递减,架构创新成为提升性能的唯一关键手段。然而,人类主导的设计方法在庞大(近乎无限)的设计空间中仅能探索约50至100个方案/代,占比不足0.001%。这种模式在过去红利时代尚可运行,但在当前每代需在相近晶体管预算下实现2倍性能提升的稀缺范式下已不可行。本文提出一种替代方案:通过多层级评估流水线,每周自动生成并评估数千个候选架构,基于部署遥测数据形成持续反馈循环。初步结果表明,该系统可将架构设计周期从数月压缩至数周,探索规模远超任何人工团队。预计两年内,纯人工架构研究将如人类棋手面对引擎般过时。

原文摘要 · Abstract (English)

The end of Moore's Law and Dennard scaling has fundamentally changed the economics of computer architecture. With transistor scaling delivering diminishing returns, architectural innovation is now the primary - and perhaps only - remaining lever for performance improvement. However, we argue that human-driven architecture research is fundamentally ill-suited for this new era. The architectural design space is vast (effectively infinite for practical purposes), yet human teams explore perhaps 50-100 designs per generation, sampling less than 0.001% of possibilities. This approach worked during the abundance era when Moore's Law provided a rising tide that lifted all designs. In the current scarcity paradigm, where every architecture must deliver 2X performance improvements using essentially the same transistor budget, systematic exploration becomes critical. We propose a concrete alternative: automated idea factories that generate and evaluate thousands of candidate architectures weekly through multi-tiered evaluation pipelines, learning from deployed telemetry data in a continuous feedback loop. Early results suggest that such systems can compress architectural design cycles from double-digit months to single-digit weeks by exploring orders of magnitude more candidates than any human team, and do it much faster. We predict that within 2 years, purely human-driven architecture research will be as obsolete as human chess players competing against engines.
