US Initiates 337 Investigation on AI Server Power Products, 20 Companies Listed

On October 10, according to Tonghuashun news, on October 9 Eastern Time, the U.S. International Trade Commission (USITC) announced the initiation of a 337 investigation into 'certain vertical power transmission systems, their components, and computing systems containing such systems,' targeting the power supply segment for AI servers. A total of 20 companies are named, including Luxshare Precision, Foxconn Industrial Internet, Hon Hai, Hongbai Technology, Delta Electronics, Quanta Computer, Cloud Computing, Infineon, ChipSource Systems, Flex, and Tianhong Technology, spanning mainland China, Taiwan, the United States, Germany, Singapore, and Canada. The investigation stems from a complaint filed by Massachusetts-based power module manufacturer Vicor on September 9, alleging that the products in question infringe its patents and requesting the issuance of a limited exclusion order and a cease-and-desist order. This marks Vicor's third similar complaint in three years. According to USITC procedures, a target date for conclusion will be set within 45 days of the case being filed, and it will take a considerable amount of time to reach a formal conclusion.

  • State Council Issues Guidelines for Building a National Blockchain Network

    On October 9, according to Xinhua News Agency, the Central Committee of the Communist Party of China and the State Council issued the "Opinions on Developing New Quality Productive Forces," which consists of seven sections and nineteen articles. The guidelines propose leading with technological innovation and focusing on significantly enhancing total factor productivity as a core indicator. They emphasize innovation-driven development, reform as a key priority, adapting to local conditions, and establishing foundations before breaking new ground. In terms of industry, the guidelines call for cultivating and expanding emerging industries, strategically planning for future sectors such as quantum technology, biomanufacturing, hydrogen energy, nuclear fusion energy, brain-computer interfaces, embodied intelligence, and sixth-generation mobile communications. They also advocate for the comprehensive implementation of the "AI+" initiative to accelerate the application of new-generation intelligent terminal scenarios like humanoid robots. Regarding incentives and financial support, the guidelines propose establishing a corporate R&D reserve fund system, increasing the proportion of deductible R&D expenses for enterprises, and improving support policies for long-term capital investment in early-stage, small-scale, long-term, and hard technology projects. They aim to strengthen patient capital, enrich the system of technology innovation bond products, support quality tech enterprises in going public for financing, and optimize systems for mergers, acquisitions, and equity incentives for tech companies. The guidelines also stress the importance of avoiding superficiality, seeking grandiosity, and creating bubbles. They strictly prohibit the abuse of policies under the guise of developing new quality productive forces and will hold serious accountability for significant losses caused by blind investments and herd behavior.

  • NVIDIA Reportedly Halts Production of RTX 5090 High-End Gaming GPU in Favor of Expensive Professional Cards

    On October 10, NVIDIA may have ceased production of the most powerful consumer graphics card, the RTX 5090, reallocating its core chips to higher-priced professional graphics cards. Hardware leaker MEGAsizeGPU claims that all future production of the GB202 chip will be supplied exclusively to the RTX PRO series, with no further use for the RTX 5090. Another leaker, hongxing2020, shared what appears to be a factory notice indicating that the China-exclusive version is also included in the production halt. Both utilize the same series of GB202 chips, but there is a significant price difference: the RTX 5090, equipped with 32GB of memory, was initially priced at $1,999, while the RTX PRO 6000, aimed at AI development and design, features 96GB of memory and is listed at $16,000 on the official website, eight times the price of the former. The RTX 5090 has already been out of stock in the U.S. market, with third-party sellers previously listing it for $9,600. If the production halt is confirmed, consumers will only be able to rely on remaining inventory. Additionally, there are reports that NVIDIA is preparing to launch a 24GB version of the RTX 5080 to replace the RTX 5090 as the highest-end gaming graphics card, while the current RTX 5080 has only about half the CUDA cores of the RTX 5090, resulting in approximately 30% lower performance in 4K gaming.
  • Putin States Negotiations with Ukraine Currently Impossible
