Shrinking production and resilient demand for older industrial and enterprise systems have pushed DDR4 prices above those of its newer successor, creating a costly choice for long-lived platforms.
The memory market has reached an unusual turning point. DDR4, a mature standard nearing the end of its commercial life, is now more expensive per gigabit than DDR5, its newer successor. The shift reflects a wider reordering of DRAM production as manufacturers direct more capacity towards higher-margin HBM memory for artificial intelligence servers and towards DDR5, while demand for DDR4 remains resilient in older industrial and enterprise systems.
According to a market analysis cited by J2 Sourcing, spot pricing at the end of September showed an 8Gb DDR4-3200 chip at an average of $46.32, up from $42.45 in early August, which was already a record at the time. By comparison, a 16Gb DDR5 chip was priced at $57.90. On a per-gigabit basis, that left DDR4 at $5.79 and DDR5 at $3.62, meaning the older memory was roughly 60% dearer per bit than the newer generation.
That reversal is significant because memory pricing usually falls as a product approaches obsolescence. In this case, supply is shrinking faster than demand. The result is acute pressure on sectors that depend on long-lived platforms and cannot simply migrate to a new memory standard. Intel Skylake through Comet Lake systems, AMD Ryzen 1000 through 5000 machines, early Xeon Scalable generations and Epyc platforms up to Milan all still rely heavily on DDR4, leaving manufacturers of industrial electronics, medical equipment, transport systems and defence hardware with few easy alternatives.
The supply squeeze is also reshaping vendor strategy. Tom’s Hardware reported earlier that as DDR4 prices rose sharply in 2025, some manufacturers began reconsidering production because the part had become more profitable than DDR5 in certain segments. J2 Sourcing says Samsung has stopped taking normal DDR4 orders, while Micron and SK hynix have largely wound down their original delivery plans. Samsung later extended 1z DDR4 output to December 2026, but the Swedish component supplier described that as a commercial decision rather than a sign of a longer-term commitment.
Micron has restarted some DDR4 and LPDDR4 output at its Manassas fab, targeting automotive, industrial, medical, aerospace and defence applications. Even so, J2 Sourcing argues that this is largely a transfer of production rather than a meaningful expansion of supply, and that DDR4 will account for only about 7% of Micron’s DRAM output in 2026. For electronics makers with products designed to last many years, the choice is becoming stark: buy DDR4 now at elevated prices to secure continuity, or redesign around newer memory and accept the cost and disruption of a platform change.
