AI data centers are crowding out memory capacity, and PC and smartphone shipments both fell sharply in the third quarter of 2026
In the third quarter of 2026, global PC shipments fell 20.1% year on year to 62.7 million units, and smartphone shipments fell 22.0% year on year to 255.3 million units; IDC said both were the largest declines on record. The article argues that the cause is that AI servers give priority to occupying HBM, server DRAM, and enterprise SSD capacity, leading to a shortage of consumer-grade memory; the cost share of DRAM and SSDs in PCs rose from about 15% to about 40%, and smartphone memory costs rose about 350% in a year. In the same period, monthly global semiconductor market shipments reached $159.7 billion, up 144.3% year on year, with growth coming mainly from AI GPUs, HBM, and memory price increases rather than end-device shipments.
