NVIDIA Rubin Ultra GPU 预览版拥有 1TB HBM 是出于供应原因,而非性能考量

SemiAnalysis 讨论了 NVIDIA 的 Rubin Ultra GPU,重点介绍了一个预览版,该预览版每封装拥有 1TB 高带宽内存 (HBM),远超目前出货产品中的 192GB。Myron XieJordan Nanos 的对话表明,这种差异主要是由于供应限制,而非性能限制。Xie 解释了 4-High (4-HI) 堆叠方法如何增加每个晶圆可用的芯片数量,并指出对内存需求减少的讽刺之处在于,它来自于研究实验室本身,他们预计未来内存短缺将会缓解。 AI

影响 为未来高性能 GPU 的内存配置和供应链考量提供了见解,与人工智能硬件规划相关。

    Myron Xie joins @JordanNanos on why NVDA's Rubin Ultra preview had 1TB of HBM per package vs the 192GB that ships. It comes down to supply and not performance, why 4-HI more than doubles the cubes you can harvest per wafer, why the loudest calls for less memory are coming from
