Group 4: Memory - The memory sector has seen a significant market rally, with expectations for the upcoming IPO of CX, which is projected to reach a trillion-dollar market value [9]. - The current market dynamics differ from previous years, with major manufacturers likely to maintain production levels to capitalize on profitability rather than rapidly expanding capacity [9]. Group 5: Liquid Cooling - The liquid cooling market is expected to grow 5-10 times next year, driven by increasing demand from chip manufacturers facing thermal management challenges [10][11]. - Innovations in liquid cooling technologies, such as multi-channel covers and immersion cooling, are being explored to enhance performance [11]. Group 6: AI Power - The AI power sector remains a focus, particularly in the context of stable and continuous power supply, which is more readily available in domestic markets compared to North America [12]. - Opportunities in AI power are identified in areas such as gas turbines and energy-efficient solutions for data centers, with a notable increase in interest in off-grid power technologies [12].

晚上关于字节要采购昇腾100亿+400亿的新闻已经刷爆了各个群，按照这个新闻的描述，已经采购了 百亿即将交付，2026年会采购400亿，那加起来就是500亿了，跟前几天传的小作文的数字是一样 的。 在周五的文章中，我们提到过这个合作，我自己问到的是目前有100亿的合作，但后续合作的金额还 不知道。 其实理性分析一下这400亿，即便字节有意愿，也不会直接下单400亿了，毕竟950还没有量产出来， 所 以可能是个框架性的采购协议，具体能落地多少，要看950的实际表现了。 从目前业内朋友对950的分析，我对950还是比较有信心的。 关于昇腾的片间互联，这里简单说一下，在目前昇腾出货量最多的8卡机里面，8个NPU的互联方式 主要采用HCCS高速缓存一致性系统，这是华为自研的高速互连技术，对标NVIDIA的NVLink，用 于实现NPU之间的低延迟、高带宽通信，支持缓存一致性和直接内存访问。8个NPU通常分为两个组 （每组4个NPU），每个组的4个NPU通过HCCS实现全连接（full-mesh）拓扑，提供更高带宽和更 低延迟；8个NPU使用6个高速线模组，总的价值量大概是5.5w左右。 关于高速线模组的测算，网上有个 ...

Summary of Key Points from the Conference Call Industry and Company Overview - The conference call primarily discusses **Huawei** and its developments in the **data center** and **high-performance computing** sectors, particularly focusing on the **384 node system** and advancements in **liquid cooling** and **high voltage direct current (HVDC)** technologies. Core Insights and Arguments - **384 Node System**: The 384 node system is considered a transitional product with performance improvements over the 920B model, but still lacking in certain precision operations. Future products like the 950 and 960 are expected to enhance performance further [1][3][5] - **HVDC Adoption**: Huawei plans to adopt **800V or higher HVDC** systems to improve power supply efficiency and reduce energy consumption. A mixed mode of AC to DC UPS and HVDC is anticipated to be implemented by 2025-2026 [1][4][10] - **Liquid Cooling Technology**: Liquid cooling has become a standard configuration, with the 920C model reaching a maximum power of **600W**, while the upcoming 950 and 960 models are expected to reach **1,000W** and **1,200W** respectively. Liquid cooling is deemed necessary for high power density applications despite its higher cost compared to air cooling [1][11][14] - **Cost Analysis**: The cost of a liquid cooling system is approximately **20,000 yuan per square meter**, with a total cabinet cost around **120,000 yuan**. In contrast, air cooling systems cost between **15,000 to 20,000 yuan per square meter**, totaling around **80,000 yuan** for a cabinet [14][15] - **Market Projections**: Expected shipments for the 920C model in 2025 are around **300,000 units**, while the 920B is projected at **600,000 units**. The 950 model is set to launch in Q1 2026, but with lower yield rates [3][24][25] Additional Important Insights - **Partnerships**: Huawei's SVDC project collaborates with partners like **Kehua** and **Bank of China** to advance project development [7] - **UPS Systems**: The company utilizes both international brands like **Schneider**, **ABB**, and **Vertiv**, as well as domestic brands like **Kehua** in its UPS solutions, aiming for localization [8] - **Microchannel Technology**: This technology is being explored for high heat dissipation needs, particularly in the 950 series chips, although it currently has high material costs [20][22] - **Future Trends**: The data center industry is expected to gradually transition to liquid cooling systems, especially as power demands increase beyond **30 kW** per cabinet [28][29] - **Reliability Measures**: The 2N configuration in data center power systems ensures high reliability, with a design that allows for 99.9% uptime even in dual power failure scenarios [30][31] This summary encapsulates the key points discussed in the conference call, highlighting Huawei's strategic direction in the data center and cooling technology sectors.
