Core Viewpoint - OpenAI is negotiating with Amazon for a financing deal of at least $10 billion, while considering the use of Amazon's AI chips in its operations [2][4]. Group 1: Amazon's AI Chips - The potential deal would provide Amazon's AI chip Trainium with a significant customer, as it aims to reduce reliance on Nvidia [4]. - Amazon's AWS recently launched the next-generation Trainium3 chip, which boasts a performance increase of up to 4.4 times compared to its predecessor, with energy efficiency also improving by 4 times and memory bandwidth nearly doubling [4]. - The UltraServer system built on this chip can support up to 144 chips in a single system and can scale to deploy up to 1 million Trainium3 chips, achieving a total scale that is 10 times that of the previous generation [4]. Group 2: Industry Trends - The move by OpenAI to incorporate Amazon's chips indicates a broader trend among leading AI companies to diversify their supply chains and reduce dependency on a single supplier [4].

AI芯片市场暗流涌动。 巨头之一谷歌正加快自研AI芯片TPU的商业化步伐，有报道称谷歌正与Meta等科技大厂谈外采合作。在 外界看来，如果合作落地，TPU将进入谷歌体系之外的超大规模数据中心，或对英伟达GPU 主导的算 力市场带来冲击。 相关消息一出，英伟达股价随即震荡。周二美股早盘，英伟达股价一度下滑7%，最终收跌约2.6%。而 自10月29日以来，英伟达市值从5.03万亿美元跌至11月25日收盘的4.32万亿美元，不到一个月时间市值 缩水已超过7000亿美元（约合人民币5万亿元）。 11月26日凌晨，英伟达在社交平台上正面回应谷歌的竞争："我们对谷歌的成功感到高兴——他们在人 工智能领域取得了重大进展，而我们仍将继续向谷歌供货。英伟达领先行业整整一代，是唯一能够运行 所有AI模型，并可在所有计算场景中部署的平台。" 作为全球GPU市场的主导者，英伟达用"领先一代"与"全场景优势"回应这场自研芯片带来的挑战。而即 便谷歌TPU得以进入Meta等巨头的数据中心，也并不意味着GPU会在短期内被替代。事实上，谷歌也表 示，自家定制的TPU和英伟达GPU的需求都在加速增长。 记者丨倪雨晴 编辑丨张伟贤 更多业内观点 ...
