Market Overview and Demand Drivers - The global HBM (High Bandwidth Memory) consumption is expected to reach 16.97 billion Gb by 2025, with an annual growth rate of 162.2%, driven by unexpected demand from NVIDIA and AWS for AI chips [3] - NVIDIA holds a 70% market share, with its HBM3e 12hi products being the main demand driver, while AWS's share increases to 8% due to geopolitical risks [3] - HBM3e series dominates the market with over 95% share, while HBM3 and HBM2e are gradually exiting the market [3] Supplier Competitive Landscape - SK Hynix is projected to ship 12.4 billion Gb in 2025, capturing 52% market share, benefiting from exclusive supply to NVIDIA [4] - Samsung Electronics faces short-term challenges due to certification delays, with a revised shipment forecast of 6.8 billion Gb and a market share drop to 29% [4] - Micron Technology is expected to achieve a shipment of 4.5 billion Gb in 2025, increasing its market share from 4% to 19% due to aggressive capacity expansion [5] Customer Demand Dynamics - NVIDIA's demand is driven by upgrades in the Blackwell platform, with a 36% quarter-on-quarter increase in HBM consumption in Q1 2025 [6] - AMD's MI350 series faces stagnation in market share at 7%, with reliance on Samsung for HBM3e 12hi limiting its bargaining power [6] - Google and AWS show diverging ASIC demand trends, with AWS increasing its share to 8% through a multi-supplier strategy [7] Technological Evolution and Cost Challenges - The mass production of HBM3e 12hi is a key technological breakthrough for 2025, increasing single-chip capacity from 24GB to 36GB [8] - Production challenges arise from increased TSV perforation numbers, with initial yields at 65% for SK Hynix and 75% for Micron [8] - Innovations in packaging technology, such as NVIDIA's CoWoS-L, increase complexity and costs, while HBM4's larger die size raises unit costs [8] Supply-Demand Balance and Long-term Risks - The HBM supply-demand ratio is expected to narrow to 39.7% in 2025 from 88.6% in 2024, indicating a trend towards balance [9] - Hidden risks include long CoWoS packaging cycles leading to stockpiling, and potential demand slowdown due to algorithm optimizations [9] - Long-term growth in the HBM market will depend on technological iterations rather than mere capacity expansion, with NVIDIA planning to launch a next-generation platform with 512GB capacity by 2028 [10]

Core Viewpoint - The article discusses the impact of U.S. export controls on semiconductor technology, particularly focusing on NVIDIA's adjustments to its supply chain and the implications for Chinese tech companies [2][3]. Group 1: NVIDIA's Supply Chain Adjustments - NVIDIA has informed three Chinese tech companies about its supply chain adjustments in response to U.S. government export control policies [2]. - The adjustments are linked to the U.S. restrictions initiated in October 2022, specifically targeting high-performance computing chips for AI training [2]. - NVIDIA previously created "downgraded" versions of its chips, A800 and H800, for the Chinese market, but these are now also restricted under new regulations [2]. Group 2: Impact on Chinese Tech Companies - The three companies likely include major Chinese server manufacturers and AI firms, such as Inspur and Huawei, which heavily rely on NVIDIA GPUs for AI model training and data center construction [3]. - These companies may face short-term challenges, including power shortages and delays in research and development [3]. - Some firms are testing domestic chips like Huawei's Ascend and Cambricon, but compatibility and performance issues remain significant hurdles [3]. Group 3: Long-term Implications for the Semiconductor Industry - U.S. technology controls may accelerate the domestic replacement of AI chips in China, with products like Huawei's Ascend 910B achieving 80% of the performance of international mainstream chips [3]. - The software ecosystem for these domestic chips still requires improvement, and some companies are exploring RISC-V architecture or distributed computing solutions to reduce dependency on foreign technology [3]. - The U.S. policies are leading to a bifurcation in the global semiconductor supply chain, creating different technical standards for Chinese and non-Chinese markets [3].
