上周,半导体行业研究机ĉ00;SemiAnalysis发布机构级报告称,英伟达将把美光HBM4排除在Rubin架构的首年量产之外,主要采用韩国公司产品。该机构预计,SK海力士将占据英伟达HBM4供应量的70%,三星电子将占据30%。
Vera Rubin是英伟达正在开发的下一代Blackwell人工智能芯片平台(Vera CPU搭配Rubin GPU),该系统将首次采用HBM4(第四代高带宽内存),以实现超高速的数据访问。SemiAnalysis指出,目前无迹象表明英伟达会向美光订购HBM4,且美光HBM4工程样品在引脚速率方面仍低于目标规格。受此消息影响,美光科技股价夜盘跌超1.2%。
三星和SK海力士HBM4样品的引脚速率约为10Gbps,而美光HBM4样品引脚速率明显较低,这一差距凸显了HBM4技术复杂度的显著提升,将影响其市场份额及量产爬坡时间表。
在更细分层面,三星HBM4前端制程在性能和能效方面具备竞争力,在某些情况下功耗甚至低于SK海力士;而海力士在信号完整性方面仍占优势,更Ľ..
