DDR4 Outgains DDR5 Over Three Months as Makers Exit Old DRAM and Phone Makers Cut Builds
Barclays data show DDR4 contract prices up 24% in three months against 20% for DDR5, while 4Q26 DRAM contracts were revised to +10-15% and NAND to +15-20%, pushing global handset shipments down 20%.
Contract pricing is running far ahead of spot. A mid-October channel survey carried by 10jqka shows fourth-quarter 2026 memory contract price forecasts revised sharply higher: conventional DRAM moved to a 10-15% quarter-on-quarter increase from an earlier 3-8%, NAND Flash to 15-20% from 0-5%, and total DRAM including HBM to 15-20%. Enterprise SSD is the standout at 23-28% for the quarter, while PC DRAM is seen up 13-18% as restocking demand compounds the supply squeeze. The same research lifted long-cycle assumptions too, putting 2027 HBM average selling prices up about 121% year on year with HBM4e breaking through $5 per Gb, and lifting 2027 DRAM capital spending to $150-160bn from $98bn in 2026.
The more surprising detail is that the older generation is outperforming. Eastmoney's 17 October note cites Barclays' October industry report showing DDR5 contract prices up 8% month on month and 20% over three months, while DDR4 contracts rose 4% on the month but 24% over three months. The reason is supply: Samsung, SK hynix and Micron have largely completed their exit from consumer and datacentre DDR4 and shifted capacity to HBM and DDR5, creating a supply vacuum that cannot be refilled quickly. DDR4 demand is also highly inelastic because it is still deployed across desktops, servers, industrial equipment and embedded systems, and the two standards are not interchangeable, so installed-base replacement and expansion orders have nowhere else to go.
Spot has cooled even as contracts accelerate. TrendForce's 16 October data show the DDR5 16Gb spot average up just 0.28% week on week, with DDR4 16Gb and 8Gb spot averages flat, indicating near-term spot momentum is losing steam even as quarterly contracts climb. Supply is structurally biased toward the premium end: HBM consumes more than three times the wafer area of conventional DDR5 and has difficult yield ramps, so every incremental HBM line displaces conventional server DRAM and enterprise NAND capacity. Equipment lead times and fab qualification cycles mean meaningful new bit supply is not expected until the second half of 2027, and QLC is projected to rise from 18% of enterprise SSD capacity in 2026 to 38% in 2027 as agentic retrieval, vector databases and KV-cache offload pull demand toward very large drives.
The demand-side damage is now measurable. DIGITIMES reported that global smartphone shipments fell 20% year on year in the third quarter of 2026, their lowest third-quarter level since 2012, as persistent DRAM and NAND shortages inflated production costs, constrained supply and weakened demand. Samsung led with a 23% share and Apple reached a record third-quarter share of 22%, highlighting a widening split between premium and price-sensitive segments. In other words, memory makers are capturing the pricing while handset brands absorb the cost, and the affordability squeeze is now showing up in unit volumes rather than in component prices.
