英伟达铁王坐不稳?ASIC成“心腹大患”,三大软肋暴露无遗
3 6 Ke· 2025-07-08 23:33
几天前,英伟达再一次创造了历史。 7 月 3 日,英伟达市值短暂攀上 3.92 万亿美元,超越了苹果此前保持的 3.915 万亿美元纪录,成为有史以来市值最高的上市公司。AI 算力的狂飙猛进,把 这家 GPU 厂商推向了前所未有的高点。 尤其是自 2024 年底,性能与能效双双跃进的 Blackwell 平台开始出货后的销售表现,打破了外界的疑虑,英伟达创始人兼 CEO 黄仁勋在最新财报电话会议 上表示,仅在 2025 年第一季度,这套新平台就已经贡献了英伟达数据中心收入的近七成。 但就在英伟达市值冲顶、光环加身之时,来自生态内部的裂缝也在浮现。最典型的例子,正是英伟达的重要客户—— OpenAI。几乎就在英伟达市值达到高 峰的同时,The Information 援引 OpenAI 内部人士称,OpenAI 正在使用谷歌自主研发的 TPU 芯片来为 ChatGPT 及其其他产品提供算力支持。 TPU 服务器,图/谷歌 虽然后续的回应中 OpenAI 刻意淡化了「转向」,强调是测试且「暂无大规模采用计划」。但对于一家曾亲手定义 AI 新时代的公司来说,哪怕只是「测 试」,也足以引发市场的高度敏感。 与此同时, ...
复盘国内外AI,兼论恒生科技
小熊跑的快· 2025-07-07 09:45
4.7 日后,中美两国股市都迎来了一轮上涨: 纳斯达克累计涨幅 32.9% 。恒生科技指数 ETF ( 513180 )累计涨幅 11.57% 。上证涨了 12.16% 。 A 股整体的上涨幅度没有美股大,从结构上看,也有 很大的差别。 逻辑是对的: 训练芯片以 H100 和 H200 为首,从 2.28 日以后其主力云上价格是往下得: 分析里面的原因:还是基础大模型的迭代变慢所致,在 transformer 架构下的基 础模型迭代明显变慢了,去年 11 月我们还能说是因为算力不够的原因,大 模型迭代受阻。但是从今年 3 月 B200 开始交付, 5 月以后情景看,基础模型的升级就是变慢了。而且从我们跟踪的行业趋势看,预训练美国大厂们还没 放弃,但是基本都把大模型迭代的重点全力投向了 RL 强化学习路径,马上要出来的 GPT5 也是这方面的集大成者。 RL 后训练强化学习阶段,老黄也认为遵 循 scaling law 法则,但比起预训练的暴力增参的大幅需求, RL 的需求显然要小一些。所以从 2 月全球一窝蜂的 转向强化学习这个路径后, H100 和 H200 的租赁价格是明确下降的,这里面也有地区影响,比如 ...
嘉楠科技将停止其AI半导体业务
是说芯语· 2025-06-24 02:47
Core Viewpoint - 嘉楠科技 is terminating its non-core AI semiconductor business to focus on its core operations, which include Bitcoin mining machine sales, self-mining, and consumer mining products. This strategic shift is expected to significantly reduce operational costs in the coming months [1][2]. Group 1: Business Strategy - The decision to end the AI semiconductor business is primarily due to its low revenue of approximately $900,000 for FY 2024, which accounts for 15% of the company's total operational expenses, thus dragging down overall efficiency [2]. - Post-strategic adjustment, resources will be concentrated on mining equipment sales, self-mining, and consumer-grade mining machines, where the company has established a clear competitive advantage [2]. Group 2: Mining Operations - 嘉楠科技's mining business is set to launch the Avalon Q mining machine in 2025, which will be compatible with global voltage standards, and the next-generation A16 series is expected to achieve an energy efficiency ratio of 15J/TH, nearing industry-leading levels [2]. - The company has a global hash rate of 8.15 EH/s in North America, with a low average electricity cost of $0.044 per kWh, and overseas projects in Ethiopia are operating with over 95% uptime [2]. Group 3: Financial Performance - In Q4 FY 2024, 嘉楠科技 reported a 33.2% reduction in net losses and achieved positive EBITDA, indicating improved financial health [2]. - The Avalon miner series, particularly the A14 product line, saw significant revenue growth following the Bitcoin halving event in April 2024, with demand for the A15 and upcoming A16 series continuing to rise [3]. Group 4: Company Milestones - 嘉楠科技 was founded in 2013 and released the world's first blockchain computing device based on ASIC chips, marking the beginning of the ASIC era in the industry [4]. - The company underwent a name change in 2015 and achieved significant milestones in chip production, including the mass production of 28nm and 16nm chips [5][6].
