Huawei's $τ$ Chip Was Supposed to Melt?

Abstract

Heat is the sharpest concern on $τ$ scaling law --- the time-scaling principle behind Huawei's folded silicon, named for the delay $τ$ (``Tao'') it sets out to shrink. Our Kirin measurements turned that objection upside down. The reason is one every commuter already knows: on a chip, as in a workday, it is the travel that burns the majority of the energy, not the work at the desk.
