NextFin News - Samsung Electronics Co. is reportedly entering the final stages of certification with Nvidia Corp. for its sixth-generation high-bandwidth memory (HBM4) chips, with mass production and initial deliveries scheduled to commence as early as February 2026. According to reports from Nasdaq and South Korean industry sources, the Suwon-based tech giant provided initial engineering samples to the U.S. chipmaker in September 2025 and has since progressed through rigorous reliability testing. This development marks a significant turnaround for Samsung, which struggled with delayed quality certifications during the previous HBM3E cycle, allowing competitors like SK Hynix to capture a larger share of the lucrative AI accelerator market.
The upcoming HBM4 chips are designed to power Nvidia's next-generation Vera Rubin AI architecture. Unlike previous iterations, HBM4 features a 12-layer or 16-layer stack that offers nearly double the bandwidth of HBM3E and approximately 40% better power efficiency. According to TrendForce, Samsung is utilizing its advanced 10nm-class sixth-generation (1c) DRAM process for the base die, a move intended to provide higher performance and better thermal management than the 12nm processes used by some competitors. While the exact volume of the first shipment remains undisclosed, industry insiders suggest that Samsung is currently manufacturing approximately 170,000 HBM units per month to meet the anticipated surge in demand from the AI sector.
The timing of this delivery is critical for the broader semiconductor industry. For the past year, the market for high-end AI memory has been characterized by a duopoly between SK Hynix and Micron Technology, with Samsung fighting to regain its footing. By securing Nvidia's approval for HBM4 ahead of the full-scale rollout of the Vera Rubin platform, Samsung is positioning itself to reclaim its status as a primary supplier. This shift is expected to alleviate the chronic supply shortages that have plagued the AI hardware industry, as U.S. President Trump’s administration continues to emphasize domestic and allied technological self-sufficiency in the face of global competition.
From a technical perspective, the transition to HBM4 represents a fundamental change in memory architecture. For the first time, memory manufacturers are integrating logic processes directly into the base die of the HBM stack. Samsung’s decision to use its own foundry services for this logic layer—rather than outsourcing to TSMC as SK Hynix has done—demonstrates a vertically integrated strategy aimed at maximizing margins and reducing supply chain complexity. However, analysts note that yield remains a pivotal challenge. According to DealSite, while Samsung’s 1c DRAM yields for standard DDR5 have reached 70%, HBM4 yields are currently estimated at around 50%, necessitating further optimization before full-scale mass production reaches peak efficiency.
Looking forward, the entry of Samsung into the HBM4 supply chain will likely trigger a price war that could benefit AI infrastructure providers. Reports indicate that Samsung is currently in price negotiations with Nvidia, aiming for a per-unit price in the mid-$500 range, closely matching the rates set by SK Hynix. As the AI industry moves toward more customized silicon solutions, the ability of Samsung to offer a "one-stop shop" involving both memory and foundry services may provide a long-term competitive advantage. If the February deliveries proceed without technical hitches, the second half of 2026 could see a significant rebalancing of market power in the global semiconductor landscape.
