当大家依然在关注光模块、PCB的时候，我们十一假期期间就一直在提电力了，也写过一篇 分析： 如果电力是AI发展的瓶颈，中国是否在领先？ 这段时间我们也经常刷到OpenAI的各种新闻，OpenAI跟AMD、英伟达、甲骨文和 CoreWeave 的交易将 在未来十年内为 OpenAI 提供超过 20GW的计算能力，约等于 20 座核反应堆的电力，而美国目前的电 力情况不容乐观，所以我们认为：目前AI数据中心的下半场，电力和节能是发展的主线。 AI需要的电力与日俱增 从需求端分析，人工智能数据中心的指数级扩张将推动电力需求快速增长。根据Rand的数据预测，到 2030 年，单个地点的 AIDC 训练需求所需电力可能达到 8 吉瓦（GW），这一规模大致相当于 8 座大型 核反应堆的总装机容量；与此同时，数字货币挖矿等领域的电力需求也在持续增长，进一步加剧了电力 消耗压力。 再看供给端，美国现有地面电力基础设施已难以在短期内适配这种爆发式增长的需求。以美国数据中心 核心聚集区 ， 弗吉尼亚州北部为例，当地部分数据中心正面临长达 7 年的电力供应排队等待问题；甚 至像 xAI 这样的企业，也因电力供应等待周期过长，不得不 ...

当然对国内来讲非常重要的就是，一方面从模型层面上来讲，国内的DeepSeek-R1，包括像字节豆包等 大模型从技术实力或者从表现上来讲也在不断追赶海外的头部大模型，另一方面国产的GPU市场还是 有比较巨大的投资机会。 有一些国产的算力产业链标的，前几年还处在业绩亏损的状态，但是在今年市值出现了比较明显的增 长，或者说股价涨幅会比它短期的业绩释放更早。所以大家就会有很多疑问，是不是这里面会存在一些 涨幅过高或者说估值过高的问题。但从产业趋势层面上来讲，包括我们去看市场空间层面来讲，我们觉 得国产算力或者说国产GPU层面还是有比较巨大的投资机会的。 首先我们看到，今年在英伟达二季度的财报说明会里，黄仁勋最新的表述也提到，整个国内能够提供的 算力芯片市场就能够达到500亿美金的体量，并且未来每年还会有差不多30%的年均复合增速。算力芯 片市场折算下来差不多就是3000多亿人民币到4000亿人民币的体量，这个体量我觉得相对还是比较庞大 的，并且未来每年还能够会有30%的增速。 但是在今年我们看到，一方面是由于海外的制裁，另一方面国内也在积极推进算力芯片，包括GPU，包 括国产的ASIC渗透率提升等等。所以未来几年我们 ...
