NVIDIA and SK Hynix Lock Down HBM4/5 Roadmap, Cementing Vera Rubin Supply Chain
NVIDIA and SK Hynix sign a multi-year agreement to co-define HBM4 production and HBM5 pre-research for Vera Rubin GPUs. Samsung also enters HBM4 supply as a second source. The deal elevates SK Hynix from vendor to co-developer, potentially creating a de facto memory standard barrier that marginalizes Micron and others.
