Samsung Takes Early Lead in Nvidia's Custom NVHBM Memory

Samsung Electronics (005930.KS) is developing an 8-layer HBM4E memory for Nvidia's NVHBM, prioritizing speed over stack height. Nvidia aims for 17-18 Gbps, 20% faster than Samsung's initial samples. NVHBM will be used in Nvidia's next-gen AI GPUs, starting with Rubin Ultra. Samsung's end-to-end capabilities give it an edge over competitors like SK hynix (000660.KS) and Micron.
