Driven by both reduced supply and intensified price competition among suppliers, contract prices for LPDDR4X in 3Q25 have seen further significant increases. LPDDR5X prices have also risen, supported by market sentiment, though the magnitude of the increase has been comparatively moderate. However, such sharp price fluctuations have added to cost pressures, with the low-end smartphone market bearing the brunt of the impact. The upward trend in prices is expected to persist in the short term.

Key Highlights

• With ongoing product upgrades and the growing prevalence of AI applications, the adoption rate of LPDDR5X continues to increase, but LPDDR4X remains the primary configuration in mid- and low-end smartphones.
• Korean and US suppliers are gradually reducing the supply of LPDDR4X, triggering panic buying in the market and driving prices to the largest single-quarter surge in nearly a decade.
• The significant rise in LPDDR4X contract prices has put considerable cost and profit pressure on mid- and low-end smartphone manufacturers.
• Currently, LPDDR5X is mainly used in mid- to high-end smartphones, notebooks, and AI servers. Overall supply and demand are relatively balanced, with prices trending upward but at a more moderate pace.
• Given the severe challenges facing both the supply and pricing of LPDDR4X, low-end device models are facing the dual risks of rising prices and potential demand declines.
