Core Viewpoint - Nvidia has notified key suppliers, including Anker and Samsung, to suspend production related to the H20 chip, potentially indicating a halt in H20 chip sales to China. However, the company may still maintain competitiveness in the Chinese market despite a 15% revenue tax imposed by the U.S. government on its sales in China [1][4]. Group 1: H20 Chip Challenges - The H20 chip has been a low-margin product for Nvidia, primarily due to U.S. regulations that limited its performance specifications, resulting in a theoretical performance of only 296 TFLOP, which is 15% of the H100 chip's capabilities [2][3]. - The H20 chip's BOM (Bill of Materials) costs may be comparable to or even exceed those of the H100 chip, as Nvidia had to equip the H20 with higher memory specifications to compensate for its reduced computational power [3][4]. - Nvidia faced a backlog of $2.5 billion in orders for the H20 chip due to a U.S. ban on sales to China, leading to $4.5 billion in costs related to unsold inventory and raw material commitments [4]. Group 2: Future Prospects with B30A Chip - A new chip, the B30A, based on the Blackwell architecture, is set to launch in the Chinese market, which may offer better performance and memory capacity compared to the H20 chip [5][6]. - The B30A chip is expected to have performance capabilities that could potentially exceed the previous flagship H100 chip, although its export to China remains uncertain [8]. - The release of the DeepSeek-V3.1 model has provided a competitive advantage for domestic GPU manufacturers, as it can seamlessly integrate with their hardware, unlike Nvidia's chips, which may not fully utilize their potential [9].
