通信周观点： 1）美国商务部 5 月 13 日升级对华芯片管制，撤销《AI 扩散规则》并出台三项新规：全球禁用华为昇腾芯片、限制美 芯片用于中国 AI 训练、强化供应链审查。此外黄仁勋受访时表示英伟达将重新推出面向中国市场的芯片，但不会再 推出 Hopper 系列产品，预计将采用 GDDR7 显存替代 HBM 高带宽内存，以满足美国出口限制要求。我们认为从性能看， 国产芯片性能或将大超英伟达改版后芯片性能，利好国产算力芯片。2）因英伟达 AI 芯片出货量不及预期（GB200 出 货不及预期，且 H20 受到管制，NVIDIA 计提约 55 亿美元的与 H20 相关的费用损失），而国内芯片供应增长需要时间， 阿里、腾讯等互联网厂商 1Q25 资本支出略低于市场预期。我们认为短期看，互联网厂商全年资本开支可能略有下滑， 但这也将加速 AI 芯片的国产替代进程。长期看伴随国产 AI 芯片的起量，AI 仍将驱动业务增长。3）英伟达 5 月 14 日 宣布在上海设立 AI 芯片研发中心，并与沙特签署 18000 台 GB300 服务器订单。此举凸显其全球布局战略，将推动高 速光模块及液冷技术需求。海外算力基建需求激增， ...
