受到英伟达等科技龙头下跌影响，上周A股科技板块同步出现调整，全球市场关于"AI泡沫"话题的讨论也急剧升温。 担心泡沫的背后，主要是科技巨头的算力需求，超出了自由现金流增长。AI算力巨头们，一方面在消耗自由现金流，另一方面正在寻求债务扩张。 对经历过2000年科网股破裂的人，"泡沫"一词并不新鲜，甚至觉得泡沫是新兴产业发展的必经阶段！AI作为当下的新兴产业，技术应用正在加速渗透至各行 各业，从产业周期角度看，AI产业仍处于康波周期的底部。 可见，提供AI应用的公司，本质上是提供"铲子"，无论哪个行业都离不开。如果说半导体、芯片类公司，提供训练和运行大型AI模型所需要的算力、存储和 平台服务，是AI生态系统的基石，而数据与算法开发、信息技术与软件服务等，提供AI应用开发的公司，就是AI的"赋能者"！ 如下图所示，人工智能、创业板人工智能、SHS云计算，3只指数今年涨幅超过60%，从SW一级行业分布来看，电子或者通信板块占比居前，而这两个板块 恰恰更能代表"AI算力"。但是，中证数据、中证软件、软件指数、软件开发、创业软件、信息安全等，今年以来表现明显落后，甚至跑输上证指数，计算机 行业在这些指数中占比明显更高。 ...

H200放开的消息今天已经传的沸沸扬扬了，国内的新闻基本都是这样写的： 但这个新闻最早 是出自彭博，比路 透要早2个多小时。 而彭博的新闻是下面这个写的，也就是说根据彭博的这个描述，目前只是初步讨论，而且完全有可 能只是停留在讨论，永远不会放开。 这事还得回溯到前段时间中美领导层见面，川普说会谈到Blackwell，大家都以为B30A会放开。后来 的事大家也都知道了，川普说没有谈Blackwell。 但又过了两天，WSJ上的消息说是因为川普的高级顾问们都反对，所以才没有谈，我们当时在星球 中就发过这个： 两国领导开会那天上午，有朋友就发我这样的截图： 所以可能高端的Hopper要放开的事也讨论了很久了。 说话正题，这次的说法是H200要放开，先看下H200的性能： | Specification | H100 | H200 | | --- | --- | --- | | GPU Architecture | Hopper | Hopper | | GPU Memory | 80 GB HBM3 | 141 GB HBM3e | | GPU Memory Bandwidth | 3.35 TB/s | 4.8 ...
