美国全球封锁华为昇腾芯片

Core Viewpoint - The article discusses the recent regulations issued by the U.S. Department of Commerce, which impose restrictions on the use of Huawei's Ascend AI chips globally, highlighting the implications for companies using these advanced computing chips [1][3]. Summary by Sections U.S. Regulations on Huawei Chips - The U.S. Department of Commerce has stated that using Huawei's Ascend chips anywhere in the world violates U.S. export control regulations [3]. - Specific models mentioned include the Huawei Ascend 910B, 910C, and 910D, which may lead to penalties for companies that utilize them [3]. Classification of High-Performance Chips - The regulations categorize advanced high-performance chips into three classes based on their total processing performance (TPP) and performance density: 1. Chips with TPP greater than or equal to 4800 TOPS, or TPP greater than or equal to 1600 TOPS with a performance density of 5.92 or higher [4]. 2. Chips with TPP between 2400 TOPS and 4800 TOPS, and performance density between 1.6 and 5.92, or TPP above 1600 TOPS with performance density between 3.2 and 5.92 [4]. 3. High Bandwidth Memory (HBM) components with memory bandwidth density greater than 2 GB/s per square millimeter [5]. Consequences of Non-Compliance - The regulations indicate that violations could result in severe penalties, including up to 20 years of imprisonment [6]. - Experts have commented that these guidelines are quite stringent, effectively forcing companies to choose between Huawei's H chips and NVIDIA's N chips [6].
