Nvidia's Vera Rubin AI platform is expected to largely rely on 12-layer high-bandwidth memory (HBM4) chips. This development eases demand concerns for SK Hynix and Samsung Electronics, as the two Korean chipmakers are advancing 16-layer HBM4 technology amid growing challenges in advanced packaging. Market researcher Counterpoint Research stated on Friday that most Rubin-based products will likely use 12-layer HBM4, the sixth generation of high-bandwidth memory, rather than the previously rumored eight-layer configuration.
