Power Usage Effectiveness: how much electricity feeds chips vs overhead.
您正在查看一条概念解释记录：该术语的通俗含义，以及它所关联的各条目。
PUE divides total facility power by IT power — 2.0 means half the electricity runs cooling and losses; leading hyperscale halls report ~1.1. Liquid cooling improves it further, but a falling PUE on an exploding IT load still means soaring total demand — efficiency and consumption rising together, the Jevons pattern in miniature. Water usage (WUE) is the companion metric communities scrutinize.
