国内AI芯片的出货量、供需关系

Core Viewpoint - The article discusses the impact of recent restrictions on AI chip sales in China, particularly focusing on the market dynamics for Nvidia and local manufacturers, and the projected growth of the AI accelerator market in the coming years [2][3]. Group 1: Market Projections - Bernstein estimates that the Chinese AI accelerator market will reach $39.5 billion by 2025, primarily driven by Nvidia H20 ($22.9 billion), AMD MI308 ($2 billion), and local manufacturers ($14.6 billion) [2]. - Following the sales ban, Nvidia is expected to lose $1.68 billion in H20 sales, while AMD may lose $150 million, with some orders shifting to local manufacturers, potentially increasing their revenue by about 10% [2]. - Despite local manufacturers' growth, Bernstein believes they cannot fully cover the $18.3 billion gap due to production bottlenecks in 7nm wafers and CoWoS technology [2]. Group 2: Nvidia's Strategy - Nvidia plans to apply for the resumption of H20 sales and introduce a compliant NVIDIA RTX PRO GPU, with initial demand projected at $10.5 billion, although it will not meet the initial demand of $16.8 billion [2][3]. - The anticipated shipment of B30 chips to China is expected to reach 400,000 units, generating $2.8 billion in revenue, while local manufacturers may only gain an additional $1.5 billion due to new restrictions [3]. Group 3: Competitive Landscape - Major cloud service providers in China, including ByteDance, Alibaba, Tencent, and Baidu, are the primary buyers of H20, accounting for 87% of total sales [5]. - By 2027, local manufacturers are projected to capture 55% of the market share, while global competitors may face technological stagnation and lose their competitive edge [3]. Group 4: Supply and Demand Dynamics - The article highlights discrepancies between GPU shipment data from Bernstein and IDC, noting that Huawei holds a 23% market share, while Nvidia's share is overstated by IDC by 7 percentage points [16][20]. - The supply-demand relationship indicates that aside from Alibaba and Baidu, other major companies are purchasing Huawei's AI chips, raising questions about the accuracy of reported data [23]. Group 5: Local Manufacturers - The report identifies local GPU manufacturers, with Huawei leading the market, followed by Cambricon, Haiguang, and Tianshu [20][21]. - The revenue of local manufacturers is expected to increase significantly, with Moore Threads projected to boost its revenue through substantial AI computing GPU shipments in 2024 [36][38].
