ChainCatcher 消息,分析指出,中国主要 DRAM 厂商 CXMT 月度晶圆产出已在 2025 年末触及约 24 万片峰值,并预计 2026 年维持持平。受美国对先进半导体设备尤其是 EUV 光刻机出口管制收紧影响,其扩产能力受限,实质性扩产最早要到 2027 年,且取决于本土设备供应链进展。高盛数据显示,CXMT 对国内 DRAM 需求覆盖率 2026 年仅约 41%,2028 年约 50%,呈现多年结构性瓶颈。
TrendForce 数据显示,传统 DRAM 合约价 2026 年一季度环比大涨 90%-95%,二季度再涨 58%-63%,Jefferies 预计三、四季度仍将分别上涨 40%-50% 与 30%-40%。服务器 DRAM 涨幅更陡,三星与 SK 海力士向微软、谷歌等客户提出一季度 60%-70% 涨价。S&P Global 预计三星传统 DRAM 每比特收入 2026 年同比升 116% 至 0.79 美元,美光 ASP 升 54% 至 1.06 美元;Bernstein 预计 SK 海力士 DRAM 毛利率 2026 年四季度可达 92.7%。
多方预测认为有效供应缓解最早要到 2027 年末甚至 2028 年。
