Investment Rating - The industry investment rating is "Overweight" as the report anticipates that the interconnection bandwidth demand will experience rapid growth due to the "multiplier effect" [4][90]. Core Insights - The report identifies four major trends in the AI computing interconnection sector: 1. Computing hardware demand is shifting from being anchored to cloud vendors' CapEx to being anchored to the number of tokens processed. 2. The landscape of computing chips is evolving from reliance on GPUs to a coexistence of GPUs and ASICs. 3. Technological iterations are transitioning from product-level upgrades (like optical modules, PCBs, switches, and network cards) to overall upgrades at the network architecture level. 4. The focus of network interconnection upgrades is expanding from Scale Out to Scale Up, enhancing both types of networks and increasing single-chip bandwidth [5][81][85]. Summary by Sections Section 1: Market Trends - The demand for computing power is increasingly linked to the number of tokens processed rather than just cloud vendor capital expenditures [5][81]. - The growth of AI models has led to a significant increase in the demand for high-bandwidth, low-latency interconnections, particularly in the context of large-scale AI training [21][25]. Section 2: Product Innovations - New products like Sora and GB200 are driving demand for multimodal inference, with Sora requiring significantly more inference computing power compared to previous models [27][35]. - The report highlights that the performance of new interconnection technologies, such as GB200, is substantially superior to older models, enhancing overall computational efficiency [75][76]. Section 3: Capital Expenditure Trends - Capital expenditures from major cloud service providers (CSPs) are expected to continue increasing, with a notable shift towards AI computing capabilities [35][37]. - The report estimates that the ratio of NVIDIA's data center revenue from cloud vendors to the capital expenditures of five major cloud vendors has increased from 5% in Q1 2023 to approximately 30% by the second half of 2024 [37][38]. Section 4: Investment Opportunities - The report suggests that various interconnection methods, including optical, copper, and PCB connections, are likely to benefit from the anticipated growth in interconnection demand. Key companies identified include: - Optical interconnection: Zhongji Xuchuang, Xinyi Sheng, Tianfu Communication, Yuanjie Technology, Changguang Huaxin, Changxin Bochuang, Shijia Photon, Zhizhi Technology, Taicheng Light. - Copper interconnection: Zhaolong Interconnection, Zhongji Xuchuang, Hongteng Precision. - PCB: Shenghong Technology, Jingwang Electronics, Hudian Co., Shengyi Technology [4][90].
