分析2026年NVIDIA HBM4供应商占比，TrendForce集邦咨询认为，基于2024至2025年的现有合作关 系，以及技术成熟度、可靠度和产能规模，评估SK hynix明年将稳居最大供应商，Samsung和Micron的 供应比重将视后续产品送样的表现而定。 智通财经APP获悉，根据TrendForce集邦咨询最新调查，因应AMD(超威)将于2026年推出MI450 Helios 平台，近期NVIDIA(英伟达)积极要求Vera Rubin server rack的关键零组件供应商提高产品规格，包括 HBM4的Speed per Pin须调升至10Gbps。尽管规格能否提升仍有变量，预计SK hynix(SK海力士)在HBM4 量产初期将维持其最大供应商的优势。 HBM4作为AI Server的关键零组件，其传输速度及带宽亦为规格精进重点。而base die为影响HBM传输 速度的重要因素。三大供应商中，Samsung(三星)于2024年将HBM4 base die的制程节点升级至FinFET 4nm，目标于今年底前正式量产，预计传输速度可达10Gbps，10Gbps产品的产出比重将高于对手SK h ...

Core Insights - The article discusses the competitive landscape in the HBM4 market, particularly focusing on NVIDIA's efforts to enhance specifications and supply chain dynamics as it prepares for the launch of the MI450 Helios platform in 2026 [2][3]. Group 1: HBM4 Specifications and Supply Chain - NVIDIA is pushing suppliers of key components for the Vera Rubin server rack to increase product specifications, specifically targeting a Speed per Pin of 10Gbps for HBM4 [2]. - HBM4 is identified as a critical component for AI servers, with transmission speed and bandwidth being key areas for improvement [2]. - Samsung plans to upgrade its HBM4 base die process node to FinFET 4nm by the end of 2024, aiming for a transmission speed of 10Gbps, which is expected to surpass competitors SK hynix and Micron in production output [2]. Group 2: Supplier Dynamics and Market Forecast - NVIDIA's strategy includes evaluating supply capacity; if supply is insufficient or if new specifications lead to excessive energy consumption or costs, NVIDIA may reconsider upgrades or categorize products based on different supplier levels [3]. - TrendForce forecasts that SK hynix will remain the largest supplier of HBM4 in 2026, with Samsung and Micron's market share dependent on the performance of their subsequent product samples [3].
