SK Hynix and Micron compete in selling high-bandwith memory chips for AI processors. There looks to be plenty of demand to go around.

SK Hynix posted record earnings in the third quarter as it continued to ride strong demand for powerful computing chips to support artificial-intelligence applications.

South Korea's SK Hynix on Thursday posted a record quarterly profit as the Nvidia supplier booked strong sales of its advanced chips, and said demand for high-bandwidth memory (HBM) chips would continue to outpace supply next year.
