华为昇腾产业链

Core Viewpoint - The article discusses the growth and investment opportunities in the AI computing center market in China, particularly focusing on the Huawei Ascend ecosystem and its associated companies across four key areas: complete machines, power supply, cooling, and connectivity [2]. Group 1: Complete Machines - The newly added computing power in 2024 is expected to reach approximately 20,000 PFlops, with the investment scale of China's intelligent computing center market projected to reach 288.6 billion yuan by 2028. In 2023, the market size was 87.9 billion yuan, showing a year-on-year growth of over 90% [3]. - As of August 2024, there are over 300 intelligent computing center projects in China, with a total announced computing power exceeding 500,000 PFlops. About one-third of these projects are planned to have a computing power greater than 500 PFlops, mainly funded by government or telecom operators [3]. Group 2: Power Supply - AI servers utilize three power supply methods: external cabinets, racks, and trays. The power supply unit (PSU) converts high-voltage AC from the grid to 48V DC, which is then further converted to 12V for CPUs and 0.8V for GPUs [15]. - The GB200 NVL72 cabinet is equipped with 48 5.5kW PSUs, providing a total power of 132kW. The increasing power demand in AI servers is expected to expand the AI power supply market [16][21]. Group 3: Cooling - The power consumption of single cabinets has increased from 4-6 kW in traditional computing centers to 20-40 kW or higher in intelligent computing centers. Liquid cooling technology is becoming the preferred choice due to its efficiency and low energy consumption [27]. - The market size for liquid cooling data centers in China was 8.63 billion yuan in 2023, with a growth rate of 26.2%, expected to reach 18.01 billion yuan by 2026 [29]. Group 4: Connectivity - Backplane connectors are crucial for high-performance servers and communication devices, supporting high-speed data transmission and ensuring signal integrity [38]. - The Chinese communication connector market is projected to grow at a compound annual growth rate of 30%-35%, with expectations to exceed 60 billion yuan by 2025, where AI-related connectors will account for over 70% of the market [40].
