国内AI芯片的出货量、供需关系
傅里叶的猫· 2025-07-21 15:42
以下文章来源于More Than Semi ,作者猫叔 More Than Semi . 我们之前写过一篇IDC出的国内AI芯片出货量的文章,当时有些读者反馈说那个数据可能有些问 题,最近Bernstein也出了一份国内AI芯片出货量的数据,但跟IDC的那个数据有些出入,当然这个 报告的内容非常全,不只包含出货量,还有供需关系,各国产GPU的情况等。 基于这个报告整理的数据已经放到星球,有兴趣的读者可以到星球查看我们整理出来的数据。还是 提醒一下,由于各GPU厂官方并未公布出货量,因此第三方给的数据仅供参考。 H20 & B30 在H20禁令前,Bernstein预计2025年中国AI加速器市场将达到395亿美元,其中主要由Nvidia H20 (229亿美元)、AMD MI308(20亿美元)和本土厂商(如华为Ascend、寒武纪、海光,总计146亿 美元)构成。禁令后,Nvidia H20损失16.8亿美元,AMD MI308损失1.5亿美元,部分订单预计将转 移至本土厂商,导致2025年本土厂商收入增加约10%。然而,由于7nm晶圆和CoWoS技术的生产瓶 颈,Bernstein认为本土厂商无法完全填补 ...

这些交易不会削弱美国的计算可用性,反而会 加强。 我们相信,这些协议具有变革性,将 把美国人工智能的人工智能基础设施提升到一 个新的水平,同时缓解电力等瓶颈。 所有美 国基础设施供应商都将从中受益。 从GPU制 造商到人工智能实验室到云计算等等。 美国与阿联酋和沙特阿拉伯的新协议在三个方 面重塑了人工智能的格局: 宏。通过避开旧的人工智能扩散出口控制框 架,华盛顿为人工智能基础设施打开了一个万 亿美元的资本闸门。 这种流入超过了迫在眉 睫的关税之争的任何拖累,并将为不仅在海湾 地区,而且在美国本土的建设提供资金,将更 多的gpu机架放在美国本土。 地缘政治。阿布扎比和利雅得现在与美国的技 术体系联系更紧密了。 如果华盛顿执行严格 的安全协议,这些联盟将加深该地区对美国硬 件和软件的依赖,并将这两个国家进一步拉入 美国的轨道。 semianalysis 人工智能进入中东:美国与阿联酋 和沙特达成协议 Dylan Patel, Jeremie Eliahou Ontiveros, AJ Kourabi, Ivan Chiam, Wega Chu, 2025年5月16日星期五 美国与阿拉伯联合酋长国和沙特阿拉伯王国 ...

Core Insights - The article discusses Intel's ambitious plan to invest over $100 billion in its semiconductor manufacturing capabilities over the next four years, focusing on the development of advanced process nodes like Intel 18A and the collaboration with TSMC to enhance production capabilities [9][15][21]. Group 1: Intel's Manufacturing Strategy - Intel's 18A process node is reported to outperform TSMC's N2 and Samsung's SF2, achieving a score of 2.53 compared to TSMC's 2.27 and Samsung's 2.1 [7]. - The collaboration between Intel and TSMC is seen as crucial for Intel to regain competitiveness in the semiconductor market, with TSMC potentially assisting in the successful implementation of Intel's 18A technology [15][21]. - The U.S. government's support is highlighted as a factor that may strengthen Intel's position in the market, allowing it to form alliances with major players like TSMC and NVIDIA [15][21]. Group 2: Market Dynamics and Competition - The article notes that TSMC holds 72% of its shares owned by foreign investors, with over half of its independent directors being American, indicating a strong U.S. influence on TSMC's operations [15]. - The increasing collaboration between Intel and TSMC may lead to a more complex competitive landscape, as both companies navigate their roles as partners and competitors in the semiconductor industry [21]. - The article suggests that TSMC's deepening involvement with Intel could alleviate some of the pressures from U.S. regulations, allowing TSMC to expand its market presence while maintaining its competitive edge [15][21].

Core Viewpoint - The recent reduction in tariffs between China and the U.S. has led to a surge in export orders from Chinese companies, indicating a potential recovery in foreign trade amidst ongoing trade tensions [2][6]. Group 1: Trade Dynamics - The current U.S. tariff rate is the base rate plus 30%, which, while still high, is an improvement from previous levels, prompting U.S. clients to expedite shipping of previously delayed goods [2]. - Following the tariff reduction, the average booking volume for container shipments from China to the U.S. increased by 277%, from 5,709 to 21,530 standard containers within a week [6]. - China's foreign trade showed resilience, with a total import and export value of 14.14 trillion yuan in the first four months of the year, reflecting a year-on-year growth of 2.4%, supported by a 7.5% increase in exports [6][7]. Group 2: Economic Outlook - Short-term expectations indicate that Chinese companies will accelerate exports to mitigate uncertainties in future trade relations, with industrial production and foreign trade expected to maintain certain resilience in the second quarter [3]. - The first quarter of the year saw a 5.8% year-on-year increase in exports, with significant growth in exports to emerging markets and ASEAN countries [7]. - Future policy support is anticipated, including potential interest rate cuts and liquidity measures to bolster economic performance amid ongoing trade negotiations [9]. Group 3: Policy and Regulatory Environment - The Chinese government remains open to dialogue to resolve trade concerns, emphasizing the importance of communication in addressing economic issues [2]. - The U.S. continues to impose restrictions, such as export controls on Huawei products, which China views as unilateral and detrimental to global supply chains [8]. - The Chinese government is expected to take firm measures to protect its enterprises' rights and interests in response to U.S. trade policies [8].

做空英伟达的时机到了么?
美股研究社· 2025-05-02 10:26
长按即可参与 到现在为止,大多数人可能都听说过中国人工智能初创公司 DeepSeek,因为它当时几乎在所有平台 都爆红。但我们认为因为 DeepSeek( DEEPSEEK )而抛售英伟达股票是不合理的,至少没有达 到那种程度。 但让我们仔细分析一下市场为何会有如此反应,这有助于我们理解如果Deepseek R2人工智能模型 的发布是否会重演这一幕。在R1发布之前,人们普遍认为中国在人工智能领域落后多年,没有机会迎 头赶上。 谷歌前首席执行官埃里克·施密特 (Eric Schmidt)曾在 2024 年 5 月表示,美国在人工智能领域领先 中国 2-3 年,原因有三:由于芯片禁令,中国更难获得英伟达芯片;获取培训材料更困难,互联 网上的信息更多是英文;最后,投资较少。领先两三年意味着中国现在的水平与 ChatGPT 的第 一个版本相同。然而,事实并非如此。 顺便说一句,DeepSeek 之前也发布过一些模型,但由于性能不佳,它们从未声名鹊起,也鲜有人使 用。然而,R1 的发布改变了一切,并表明使用更少、更老旧的 GPU 也能开发出最先进的模型。开 发人员运用了多种优化策略来实现这一点。然而,黄仁勋表示,在他看 ...
