AI产业链研究 黄仁勋又要来中国了，这次预计他将出席下周举办的链博会。老黄如此频繁的来中国，说明一个问题：中 国市场真的太重要了，英伟达放弃不起。这一次造访中国也无疑跟即将推出中国市场的阉割版blackwell芯 片B30（也有人称为B40）有关。 这篇文章我们重点来聊聊B30的情况。目前英伟达官方还没有正式发布B30的具体参数， 但根 据笔者和第三方机构的调研，目前正在大厂测试的版本是没有Nvlink，显存也不再使用HBM， 而是使用GDDR 。根据大厂的测试结果，该卡虽然不支持NVlink，但用了自己的技术实现多卡 互联，互联带宽大约100到200GB/s，算是绕开美国限制后最好的卡种。 B40在算力指标上与H20不相上下，跟主流国产AI芯片相比，单卡性能，无论是显存带宽还是算 力上都差了不少。B30仍将普遍比国产卡好用。首先CUDA生态目前仍然无法被渠道，国产卡无 论哪家，出来之后在软硬件之间的生态适配上，企业还需要做大量的兼容工作，这部分也会影响 整体的性价比。 另外最重要的一点是B30定价相当低，在6000-8500美金，一张卡可能只是国 ...

智通财经APP获悉，市场调研消息，字节开标，苏美达进了，玉柴价格报到300万; 潍柴与腾讯近期谈 标，潍柴价格报到280万，后续也可能涨超300万; 英伟达B30芯片即将出台，大厂近期已经准备开始启 动招标，下半年招明年的标，以国产柴发为主。 从外资涨价到内资引领、供需紧张时长或超预期。此前柴发涨价的核心逻辑在于外资排产拉长价格提 升，内资则是逐步导入市场，价格跟随策略为主。 市场消息：柴油发电机板块调整，主要受到芯片禁令影响下国内大厂的capex强度和节奏低于预期，目 前看，随着B卡的投放预期市场情绪有望缓解。 从近期调研看，机构预计25H2开始，随着内资排产周期拉长至明年，内资主机厂开始主导涨价旋律。 据第三方媒体快科技，NV正开发中国特供新芯片B30，计划今年生产逾100万颗。 此外，近期从海外巨头的业绩和CAPEX指引看，海外算力需求仍保持高景气，且新一轮中美会谈预期 下，市场风偏也有望改善，核心AIDC电气设备公司近期调整后性价比凸显。 柴油发电机相关港股： 潍柴动力（02338）：在机构调研中表示，2024年，公司M系列大缸径发动机销售8100余台，海外销量 占比62%。收入同比增20%，主要是数 ...

我们之前写过两篇关于英伟达特供中国阉割版H20的文章，都是基于外资投行的分析，这篇文章，我们 来看下substack上的一个分析，这个分析的内容比之前两篇的内容都要更加的详细。 原文链接：https://substack.com/home/post/p-165933497 Substack账户： Global Semi Research 本次转载已获原作者授权 正文 英伟达首席执行官黄仁勋周四在巴黎对CNN记者安娜·斯图尔特表示："未来，我们的预测将不包括中国 市场。"然而，中国对英伟达的重要性不言而喻——否则，黄仁勋不会如此努力地放大华为作为竞争威 胁的形象。他声称华为的芯片可与英伟达最先进的处理器相媲美，但这与中国市场的实际情况不符。 我们的行业调查显示，华为的CloudMatrix384——黄仁勋将其定位为可与英伟达Blackwell架构媲美的产 品——在中国市场上难以推广。虽然一些公司表示了兴趣，但尚未有实质性订单。 B20使用英伟达的ConnectX-8实现互连功能，通过以太网实现连接，最大互连带宽为800Gbps。每块B20 芯片通过NVLink总线连接到ConnectX-8芯片，形成一个相当于P ...
