Computer Architecture's AlphaZero Moment: Automated Discovery in an Encircled World

TL;DR

This paper advocates for automated, machine-driven exploration of computer architecture design space, arguing it can outperform human efforts and accelerate innovation in the post-Moore era.

Contribution

It introduces a framework for automated architecture idea factories that generate and evaluate thousands of designs weekly, significantly speeding up the design cycle.

Findings

Automated systems can explore orders of magnitude more architectures than humans.

Design cycles can be reduced from months to weeks.

Early results show promising improvements in architecture discovery speed.

Abstract

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.
