当下，一场电力饥渴正席卷全球AI产业。2025年，OpenAI在德州阿比林规划4.5GW电力接入，相当于五座核电站的发电量；微软GPU集群因电力不足 而"吃灰"；北弗吉尼亚数据中心的项目排队"等电"长达数年……这些现象指向一个残酷现实：AI竞赛的核心正从算力芯片转向电力基建。 从"缺芯片"变为"缺电" "我们现在面临的最大问题，不再是算力资源过剩，而是电力——以及能否够快地在有电力的地方完成设施建置。"微软首席执行官萨提亚·纳德拉在最近 与OpenAI首席执行官萨姆·奥特曼对话的播客节目中坦言。他补充道："如果做不到这点，我们可能会有一堆芯片躺在仓库里却插不上电。" 缺电，让微软高价购买的显卡在仓库里吃灰 回顾过去几年，AI的能耗增长速度令人震惊。据国际能源署数据，2022年全球数据中心总耗电量约460太瓦时，占全球用电量的2%；到2026年，这一数据 将超过1000太瓦时，大约是整个日本2022年全年的用电量。 "一年多以前短缺的是芯片，接下来短缺的将是电力。"而就在一年之前，埃隆·马斯克在"博世互联世界2024"大会上的警告言犹在耳。几乎在同一时间， 萨姆·奥特曼在达沃斯论坛上也表达了类似担忧，承认人工智 ...

Core Viewpoint - Amazon.com, Inc. has been downgraded to "Neutral" from "Buy" by Rothschild & Co Redburn, with a price target set at $250, due to concerns regarding AWS's potential in the generative AI market and limited upside despite its strong positioning [1][2].

Financial Implications - AWS captures more value within Amazon's overall stack, but the generative AI segment is seen as dilutive to returns, with its share increasing [4].

These chips are smaller, cheaper, accessible and could reduce these companies' reliance on Nvidia GPUs. Daniel Newman of th ...

在人工智能等新科技领域竞争日趋激烈的情况下，提振民间投 资的政策应该进一步调整着力点，合理设置"红绿灯"，让敢 投、能投、愿投的企业，挑起新增投资的大梁，成为在新科技 赛场上实现突破的关键力量。 作者：宋笛 封图：图虫创意 尽管美国AI（人工智能）投资是否存在泡沫还有待时间检验，但一个事实是：AI驱动的巨量投资， 已对美国宏观经济产生了显著影响。 2025年前两个季度，投资对美国GDP的贡献升至每季度年化1个百分点，创下2023年以来的最高 水平。美国经济的"三驾马车"中，消费长期占据主导地位，而2025年AI带动的投资，少见地让投 资对GDP增长贡献率逼近消费。这些投资主要投向了数据中心和相应设备领域。 主导这一轮投资的是美国头部企业。2025年第二季度，美股"七姐妹"（ 苹果、微软、英伟达、 亚马逊、谷歌母公司Alphabet、Meta和特斯拉）的资本开支规模近1000亿美元，较三年前同期 规模翻倍，年增速接近65%。预计2025年全年，美国科技巨头的资本开支将达到5000亿美元。 摩根士丹利预测，从2025年至2028年，全球数据中心支出将接近3万亿美元，其中1.4万亿美元 来自科技巨头。 这俨然是一个 ...
