或许是黄仁勋每天在喊"中国市场已经归零，市场要让给中国企业了"，也或许是关税战告一段落，总之，英伟达的芯片限售松开了。 特朗普于2025年12月8日宣布，美国政府将允许Nvidia向中国及其它国家/地区"经批准客户"（"approved customers"）出口H200AI芯片。 图源：网络 这是美国对过去AI芯片严苛出口管制政策的一次重大转向。 不过，美国和英伟达并未把最先进的芯片放开出售。作为折中方案，这次批准仅限H200（基于其 "Hopper" 架构、性能高于此前对华允许的 H20，但低于 Nvidia 最 新的"Blackwell"及未来"Rubin"顶级芯片），而且仅限于获批客户。 因为H200不是最顶尖的AI芯片，美国方面对"技术外泄"的顾虑会少很多，所以会把H200看作恢复对中国这一全球最大 AI 潜在市场销售能力的关键机会。 当然，还有一个原因，H200出口销售收入的25%将上缴美国政府。美国政府希望在国家安全和经济利益间找到一个平衡，在 继续控制"最先进技术"外泄 的同时， 给美国企业（Nvidia、以及如 AMD、Intel 等）一个 有限、可控但有经济回报 的出口渠道。 根据公开报道 ...
