Memory Is Eating the PC Bill, in a Bite

Memory, not compute, is what a PC buyer is paying for now.

• Worldwide PC shipments fell 20.1 percent year on year in the third quarter to 62.7 million units, the worst third quarter IDC has recorded.
• DRAM and SSDs now account for nearly 40 percent of a PC component bill, up from about 15 percent, per Omdia.
• DDR4 8-gigabit DRAM went from $6.30 a unit in September 2025 to $26.00 in September 2026, and 128-gigabit MLC NAND went from $3.80 to $30.60.
• TrendForce expects enterprise SSD contract prices to rise 23 to 28 percent this quarter, the only category where the increase accelerates.
• Micron says more than 75 percent of its 2027 output is already committed, so the queue is closed before most buyers reach it.

The AI memory shortage started at the top of the stack and worked downward. Every wafer that goes into high bandwidth memory or a server RDIMM is one fewer for the commodity parts that fill a laptop, and the bill lands on the endpoint budget.
