公众号记得加星标⭐️，第一时间看推送不会错过。 多年以后，2025年圣诞节这一天，会载入全球AI算力芯片产业发展史。 12月25日凌晨，英伟达和Groq宣布达成"非排他性授权协议"，以200亿美元（约合1400亿元）现金 价格购买一家"非GPU"架构企业的技术授权。 这场交易是英伟达有史以来规模最大的一笔"投资"，该公司将现金和短期持有资本606亿美元的三分 之一都给了这家公司，超出该公司此前估值的3倍，可见其必须拿下该项技术的决心。 这一激进动作背后，与近期谷歌TPU等"非GPU架构"的风头正劲密切相关。英伟达收购的这家芯片公 司Groq的创始人兼CEO，正是谷歌"TPU芯片"缔造者——乔纳森·罗斯（Jonathan Ross），收购后乔 纳森及Groq的核心技术成员也将集体加盟英伟达。 再来看非GPU派，包括ASIC（专用集成电路）和可重构数据流芯片，其中Groq LPU为可重构数据流 领域的"得意门生"，其精髓在于硬件能够根据瞬息万变计算任务动态重组，构建出高效专用通道，使 得AI芯片具备灵活性和专用集成电路高效性的优势。 早在2015年，可重构计算就被国际半导体技术路线图（ITRS）预见为"未来最具前 ...

文 | 下海fallsea，作者 | 胡不知 2025年12月24日，平安夜的硅谷没有温情。当大多数人沉浸在节日氛围中时，AI算力圈传来一则足以 改写行业格局的消息：英伟达宣布以200亿美元现金，与曾喊出"终结GPU霸权"的AI芯片初创公司Groq 达成技术许可协议。 "这不是收购，却胜似收购。"伯恩斯坦分析师Stacy Rasgon一针见血地指出，"本质是英伟达用金钱换时 间，把最危险的颠覆者变成自己人，同时规避反垄断审查的障眼法。" 这场交易的背后，是AI产业的历史性转折——从集中式模型训练，全面迈入规模化推理落地的新阶 段。推理市场正以年复合增长率65%的速度扩张，预计2025年规模突破400亿美元，2028年更是将达到 1500亿美元。而英伟达的GPU霸权，在推理赛道正遭遇前所未有的挑战：谷歌TPU凭借成本优势抢食大 客户，AMD MI300X拿下微软40亿美元订单，中国的华为昇腾在本土市场份额已飙升至28%。 曾被视为"GPU终结者"的Groq，为何最终选择与英伟达联手？200亿美元的天价交易，能否帮英伟达守 住算力王座？这场"招安"背后，更折射出AI芯片行业创新者的集体困境：当技术颠覆者撞上巨头的 ...
