0:00 21世纪经济报道记者倪雨晴 深圳报道 华为昇腾是怎么做到和英伟达"掰手腕"的? 技术拆解 要理解这个问题,我们得先来认识昇腾的最强战力,"CloudMatrix 384 超节点"这个大家伙。这就是它 的外观(画面:384的结构图),它其实就是一个巨大的芯片集合,这最核心的384张昇腾910芯片,外 加192颗鲲鹏CPU,通通塞进16个机柜,然后用光缆、光模块联接起来,构成一个"超节点"。 你可以把它想象成一支超级"AI方阵":虽然单个士兵不如对手,但整体配合、纪律、调度都非常出色。 最终打起仗来,不一定会输。 听起来是不是有点像"芯片大拼盘"?但是,要把384块芯片联接在一起,像一台机器一样高效工作、协 同配合,这可不简单。 你可能不知道,英伟达目前GB200的机柜,只塞了72块GPU,下一代是144块GPU, 这个"大力出奇迹"的背后,是通信、光学、热学、基础软件等多个领域的老底子,一起发力的结果。 核心突破点包括: 听上去有点技术?咱们展开说说一项很关键的互联技术。 在计算集群里,无论是 CPU、GPU 还是 NPU,最终都需要高效的联接起来,才能交换传输数据。 英伟达有独家的NVLink互联技 ...

Core Viewpoint - The article discusses the recent performance and challenges faced by Cambrian (寒武纪), highlighting its significant market value drop despite achieving profitability for the first time. The increasing competition in the AI chip sector and the diminishing uniqueness of Cambrian's offerings are key factors contributing to its stock price decline. Group 1: Company Performance - Cambrian's market value peaked at over 340 billion yuan in February but has since fallen to around 230 billion yuan [1] - The company reported its first-ever profits, with net profits of 272 million yuan and 355 million yuan expected in Q4 2024 and Q1 2025, respectively [1] Group 2: Competitive Landscape - The competitive pressure on Cambrian has intensified, particularly from Huawei and Haiguang Information, which are becoming stronger in the AI chip market [3] - Cambrian's latest chip, the Shiyuan 590, has performance close to 80% of NVIDIA's A100, but it is still outperformed by Huawei's Ascend series [5][6] Group 3: Financial Challenges - Despite achieving profitability, Cambrian's financial situation remains precarious, with negative operating cash flows of -1.618 billion yuan and -1.399 billion yuan for Q4 2024 and Q1 2025, respectively [8] - The company's cash reserves have halved to 1.972 billion yuan in 2024 and are expected to drop further to 638 million yuan in Q1 2025 [8] - Cambrian's R&D expenses are significantly high, exceeding its revenue, with Q1 2025 R&D spending reaching 235 million yuan [8] Group 4: Market Valuation - Cambrian's current market capitalization is approximately 239.6 billion yuan, which implies a required annual profit of 4.717 billion yuan to justify its valuation, necessitating a more than threefold increase in quarterly net profit [9] - The potential for a price drop in AI chips due to increased domestic competition raises questions about Cambrian's high valuation sustainability [9]
第二个将华为列入实体清单的地方出现,6000吨稀土出口该不该叫停

第二个公开将华为拉入出口黑名单的地方出现了! 就在中美之间的谈判还未尘埃落定之时,美国方面迅速采取行动,一纸禁令准确地指向了华为的昇腾910芯片。5月13日的这项禁令,传递出的信号清晰无比 ——美国意图切断中国人工智能产业的供应链,直接针对这一行业的"生命线"。这不再仅仅是商业摩擦的问题,特朗普已经不再遮掩,毫不掩饰地公开出 手。 尽管美国声称此举是出于"技术保护",更荒谬的是,所谓的理由是"可能包含美国技术"的芯片问题,简直让人觉得滑稽。然而,这仅仅是开始,后续的动作 还更为猛烈。紧随其后,台湾地区也迅速响应,迅速将华为及中芯国际列入了自己的"实体管制清单"。一场看似独立的风波,实际上是早已策划好的"围 猎"行动。 美国在前面挥舞着"技术屠刀",台湾则紧随其后,迅速加强了对中国高科技产业的围堵。两者的结合,不仅仅是为了压制中国技术发展的进程,更是两股力 量的强烈碰撞。一方面是"资源底座"——台湾几十年来自豪的半导体产业,它是台湾在全球科技领域立足的根本。另一方面,台湾却将这份"资本"作为一 张"政治名片",递给了美国。问题是,这份"投名状"背后,台湾的半导体产业,看似强大,却实际上极为脆弱。 an Coll ...
2024智算时代,国产算力链迎发展新机遇

美国为什么咬着华为不放?开始全球封杀华为AI芯片,他们怕什么?

据最新消息,在中美关税战刚刚缓和之际,美国政府又开始升级科技战,目标直指中国的华为AI芯片。美国商务部宣布:全球都要禁用华为昇腾910芯片, 否则就是违反美国的出口管制,违者最高可判20年监禁! 特朗普美国政府为什么总是像狗一样,硬是咬着华为不放?华为到底哪里得罪它了?相对于以前对华为的制裁,美国总是找一个"危害国家安全"的理由,而 这次美国没有以任何理由。如果硬要给它找出一些理由,无外乎以下3个。 一:这是美国发出的最后的嘶吼,想找回点脸面。 关税战是特朗普高喊着打起来的,想让全世界所有国家都屈服于它。可让特朗普没想到的是,中国一改以往的韬光养晦姿态,开始全面硬刚,打了特朗普一 个措手不及,最终导致美国关税战失败。所以,特朗普想通过封杀华为AI芯片,来找回一点颜面。 但美国经过关税战的失败后,其它国家还会理它吗?还会像以前那样听美国的话吗?这就要打上一个"大大的问号"了。 二:美国是真的急了,想拿华为AI芯片禁令,来换中国的稀土。 这次中美关税谈判中,美国想要的稀土,中国压根就不和美国谈,因为中国不是因为关税战而禁止稀土出口的。 现在特朗普手中可打的牌,已经所剩无几了,也就唯独华为这张牌还有点分量,所以,特 ...
