Investment Rating - The report maintains an "Accumulate" rating for the electronic industry [1] Core Viewpoints - The sentiment around domestic computing power has been accumulating since late July, largely due to speculation about the H20's ability to ship successfully. The recent discussions around the H20 chip's security risks have raised concerns about its application and safety [6] - The U.S. export licenses for NVIDIA's H20 and AMD's MI308 chips to China come with revenue sharing and "backdoor" mechanisms, which limit their competitiveness in the Chinese market. This creates an opportunity for domestic computing power to gain market space [6] - The report emphasizes that the limitations of the H20 chip in terms of performance and energy efficiency align with domestic green development goals, suggesting that the restrictions on H20 will support the growth of domestic GPU markets [6] Summary by Sections Market Sentiment - Since late July, there has been a buildup of sentiment regarding domestic computing power, driven by speculation about the H20 chip's market entry and safety concerns raised by Chinese authorities [6] Policy Impact - Recent U.S. policy changes have created a challenging environment for the H20 chip, with export licenses requiring revenue sharing and raising security concerns, which may hinder its market performance in China [6] Domestic Opportunities - The limitations imposed on the H20 chip are seen as a catalyst for domestic computing power to expand its market presence, with a focus on the need for advanced process capacity and the demand from internet companies [6]
