Core Viewpoint - The DDR4 spot price has surged dramatically, with the price of DDR4 16Gb chips now exceeding that of DDR5 chips by approximately 100%, marking a historic moment in the DRAM market [1][2]. Group 1: Price Trends - The DDR4 spot price has increased by about 50% in just two weeks, and prices have more than doubled this season [1][2]. - The average spot price for DDR4 16Gb (1Gx16) 3200 is now $12, while DDR5 16Gb (2Gx8) 4800/5600 is priced at $6.014, indicating that DDR4 is now about twice as expensive as DDR5 [2]. - The price of DDR4 8Gb (1Gx8) 3200 has risen from $1.63 to $5.2, a nearly 2.2-fold increase [2]. Group 2: Market Dynamics - Nanya Technology and Winbond are positioned to benefit from the rising DDR4 prices, with Nanya's DDR3 and DDR4 products accounting for over 80% of its revenue [2]. - Nanya is reportedly increasing its investment in DDR4 production capacity, breaking the trend of focusing on next-generation specifications, indicating a recognition of the significant market opportunity for DDR4 [2]. - The recent surge in DDR4 prices is attributed to multiple factors, including major manufacturers like Samsung and Micron halting DDR4 supply to focus on DDR5 and high-bandwidth memory (HBM) [3][4]. Group 3: Future Outlook - Adata, a leading memory module manufacturer, anticipates a 30% to 40% increase in DDR4 contract prices in Q3 due to strong demand from downstream customers [3]. - The supply constraints are expected to persist as major manufacturers are shifting their focus away from DDR4, leading to continued price increases in the future [4].
