Production of DDR4 memory and motherboards is restarting amid unprecedented memory shortages — PC industry preparing for a world without DDR5

Back to the (stone) DDR4 age.

Why this matters
Why now

Unprecedented memory shortages, particularly in DDR5, are forcing the PC industry to pivot back to older, more readily available DDR4 technology to meet demand.

Why it’s important

This move highlights a critical vulnerability in the compute supply chain and indicates a broader challenge in scaling next-generation hardware manufacturing.

What changes

The industry is now actively diverting resources back to older tech, suggesting that the transition to DDR5 is significantly delayed or facing unforeseen bottlenecks.

Winners
  • · DDR4 manufacturers
  • · PC users on a budget
  • · Companies with existing DDR4 inventories
Losers
  • · DDR5 manufacturers
  • · Early adopters of DDR5 systems
  • · PC component retailers hoping for rapid DDR5 adoption
Second-order effects
Direct

Increased market longevity for DDR4 technology and a slowdown in DDR5 adoption.

Second

Potential for innovation in other PC components to compensate for memory limitations or a re-evaluation of memory technology roadmaps.

Third

Long-term implications for the perceived reliability and resilience of the advanced semiconductor supply chain, impacting future technology transitions.
