AI memory demand squeezes PC buyers as Q3 shipments fall 20%
AI-server demand for HBM and server DRAM is crowding out consumer memory capacity: Omdia estimates memory and SSDs have climbed from roughly 15% of PC bill-of-materials cost to nearly 40%, while IDC preliminary data put Q3 2026 global PC shipments down 20.1% year over year (78.5M to 62.7M units) and Omdia measured a 21.2% decline in desktops, notebooks and workstations, with Macs also down. TrendForce calculates CPU, DRAM and SSD now account for about 68% of the BOM in a $900 mainstream laptop; Gigabyte responded on Oct. 9 by saying all its B760 and H610 boards, DDR4 included, will support new Intel LGA1700 processors expected in early 2027 via BIOS update, after adding AM4 boards alongside the Ryzen 7 5800X3D relaunch in August. On the software side, the open-source Strata project, with about 19,500 GitHub stars, reports running the 125B-parameter Qwen3.8-Flash-Next at roughly 94 tokens/s under Q2_0 quantization on a PC with an RTX 5070 (12GB VRAM), Ryzen 5 7600 and 64GB of system RAM, or about 53 tokens/s on IQ3_S.
Intelligence itself is getting cheaper while the memory and machines needed to carry it get dearer, making memory supply a practical constraint on AI adoption.
