【广发海外电子通信】 关于Rubin Ultra 设计为2-die (非市场预期4-die)。我们认为台积电产出为2-die,当前有两个版本,Rubin Ultra 2-die 和 Rubin Ultra 2+2 dies,2+2方案为在台积电产出2-dies后在PCB/CoWoP板上组成2+2 dies。后续一个Kyber compute blade 为4个2-die 或是2个2+2 dies。 因此,整体对价值量影响非常有限(我们的观点也符合GTC展示的路标图)。其中存储为高容量HBM4E (64GB per cube) ,Rubin Ultra 2-die 为512GB (8 x 64GB),组装成2+2 dies 为1024GB (和原预期一样)。相反的,我们认为价值量有不利影响的为封装、测试、等等。至于机柜数量没有影响。

[GF Securities Overseas Electronics & Communications] Regarding Rubin Ultra being designed as a 2-die configuration (versus the market expectation of 4-die): We believe TSMC’s output is 2-die, and there are currently two versions — Rubin Ultra 2-die and Rubin Ultra 2+2 dies. The 2+2 scheme involves TSMC producing 2-die units, which are then assembled into a 2+2 die configuration on a PCB/CoWoS board. Subsequently, a single Kyber compute blade would consist of either four 2-die units or two 2+2 die units. Therefore, the overall impact on value is very limited (our view is also consistent with the roadmap shown at GTC). On the memory side, high-capacity HBM4E (64GB per cube) is used — Rubin Ultra 2-die carries 512GB (8 × 64GB), and when assembled into the 2+2 die configuration, it reaches 1,024GB (in line with original expectations). Conversely, we believe the areas where value could be negatively impacted are packaging, testing, etc. As for rack quantities, there is no impact. $NVDA

由于中国稀土出口管制,法拉第旋光片缺货(海外Coherent自用、Granopt减产) 1. 供给兜底:上游晶体/旋光片国产材料替代 核心代表:福晶科技(TGG/TSAG高端)、东田微(YIG中低端)、长飞光坊TGG 2. 需求降量:通过低回光EML技术进行架构优化,减少法拉第旋光片的使用 核心代表:源杰科技、长光华芯、东山精密(索尔思光电)
