HBM Allocation to AI Datacenters Reprices Consumer Electronics — Wafer Capacity Constraint Bites

Summary

David Oks' analysis, surfaced by Simon Willison, lays out the wafer-capacity arithmetic behind the consumer memory shortage now repricing low-end electronics. Three memory manufacturers control DDR (desktops/servers), LPDDR (mobile), and HBM (GPUs) production, all sharing a fixed wafer pool. HBM allocation has gone from 2% to an expected 20% of wafer capacity by end-2026 driven by AI datacenter demand, and critically, a gigabyte of HBM consumes more than 3x the wafer capacity of a gigabyte of DD
