The AI boom isn’t just transforming datacenters—it’s reshaping the entire memory market. With cloud giants racing to expand high-performance computing capacity, demand for high bandwidth memory (HBM) keeps absorbing precious wafer capacity. The ripple effect is now hitting consumer tech hard: LPDDR5x, the low‑power memory that powers flagship smartphones, is on track for sharp price increases.
A key factor behind the squeeze is simple physics and economics. HBM dies are roughly 35–45% larger than comparable DRAM dies, consuming more wafer area and production time. As more capacity shifts toward HBM stacks for AI servers, less is left for conventional DRAM like DDR5 and LPDDR5x—tightening supply and pushing prices up.
A new forecast underscores how quickly the market is tilting. TrendForce has revised its outlook as follows:
– DRAM contract prices are rising as global cloud providers expand orders.
– The Q4 2025 forecast for conventional DRAM has been raised from 8–13% growth to 18–23%, with room for further upside.
– Global server shipments are expected to climb 4% year over year in 2026.
– Rapid upgrades to high-performance computing platforms are driving DRAM bit demand above earlier expectations, extending the structural shortage.
– DDR5 contract prices are likely to keep increasing throughout 2026, especially in the first half.
– HBM contract prices could shift into year-over-year decline in 2026 as competition intensifies and HBM3e inventories look healthier.
– As of Q2 2025, HBM3e carried about a 4x price premium over DDR5.
– By Q1 2026, DDR5 profitability is projected to exceed that of HBM3e.
These dynamics are already visible on the ground. DDR5 lead times have stretched to roughly 26–39 weeks, a classic sign of scarcity and a precursor to higher pricing across adjacent categories. That pressure is seeping into smartphones. LPDDR5x sits squarely in the crosshairs because it shares production resources and market forces with broader DRAM. In other words, what hurts DDR5 today often hits LPDDR5x next.
Industry voices are sounding the alarm. Xiaomi’s president, Lu Weibing, recently warned that storage costs are rising faster than expected and are likely to keep climbing, noting that no single manufacturer can reverse global supply chain trends. Chip designers feel the strain too. MediaTek’s margins are under pressure just as it transitions to 2nm, a node where wafer prices at leading foundries can reach around $30,000 each. When core components become that expensive, device makers have limited choices: absorb the hit, cut features, or raise prices. Rumors already suggest that some top Android brands are evaluating smartphone price adjustments for next year.
What this means for consumers and the industry:
– Premium phones could see higher retail prices or tighter SKUs for high‑RAM configurations.
– Mid‑range devices may ship with more conservative memory options to manage bill of materials costs.
– PC builders and enterprise buyers should anticipate continued DDR5 cost inflation through at least the first half of 2026, even if HBM prices ease from today’s peaks.
A quick refresher: LPDDR5x is a high‑performance, low‑power DRAM used in smartphones, tablets, and thin laptops. It delivers fast data rates while preserving battery life, which is why it’s essential for modern mobile devices. Because it is part of the same broader DRAM ecosystem affected by AI‑driven supply shifts, LPDDR5x pricing tends to react when server memory markets tighten.
The bottom line: AI’s appetite for HBM is reordering priorities across the semiconductor supply chain. TrendForce’s higher Q4 2025 DRAM price outlook and its 2026 trajectory for DDR5 suggest that the supply crunch won’t vanish overnight. Even if HBM3e prices cool as inventories improve, the imbalance created by relentless HPC upgrades keeps conventional DRAM tight—and that’s why LPDDR5x costs are poised to surge, with smartphones likely feeling the impact first.
