Hot Chips 2026: Samsung advances LPDDR5X-PIM as HBM costs mount

Samsung's unveiling of LPDDR5X-PIM at Hot Chips 2026 marks a pivotal step from concept to deployment, directly impacting memory controller, AI accelerator, and SoC architecture evolution. This advancement intensifies pressure on HBM costs, offering a viable alternative. From a compliance standpoint, the technology shift may prompt global supply chain realignment, especially amid U.S.-China tech decoupling, where Taiwan, China's semiconductor capabilities are increasingly scrutinized. Competitors like NVIDIA and AMD may accelerate in-house PIM development to maintain edge. Over the next 12–24 months, PIM is expected to rapidly gain traction in data center and edge AI inference, reshaping market dynamics and forcing HBM vendors to adjust pricing and demand strategies.
