Samsung Supplies HBM4 Modules To NVIDIA Vera Rubin

Samsung's HBM4 memory modules are expected to be used in NVIDIA's Vera Rubin AI lineup as soon as June 2026, with customer shipments slated to begin in August and full chips displayed at GTC 2026. Samsung's HBM4 is rated at 11+ Gbps and uses an internal 4nm logic-base die, which the company says enables higher pin speeds and more reliable supply than rivals. The adoption supports higher memory specifications for agentic AI workloads.
