Huawei's τ-Scaling Law: A Real Read of the Paper Behind the Hype
TL;DR — Huawei’s τ (Tao) Scaling Law, announced at IEEE ISCAS 2026, reframes Moore’s Law: instead of shrinking transistors, optimize a time constant τ across the entire computing stack. The paper is real, the production data is concrete, but the “first scaling law since Dennard” claim deserves scrutiny. This is mostly a solid 3D-integration engineering paper wrapped in a strategic narrative about how China builds high-performance chips without leading-edge lithography. ...
