DigiTimes (via TechPowerUp) has reported that DDR3 memory prices are expected to rise between 40 and 50 percent in 2021. This comes as quite a surprise, as DDR3 was introduced back in 2007 and DDR4 has largely become mainstream at this point. DDR5 is already in the wings, as companies have begun validation or production phases.
The price hike is due to SK hynix and other major manufacturers scaling back or stopping DDR3 production. Some 2 GB and 4 GB modules have already increased in price by 30 percent. This points to the efficiency and longevity of older tech. It is also a sign of the times, with many upgrading older PCs during the pandemic rather than committing to the higher costs or unavailability of newer technology.
