芯东西2月5日报道，今日，美国AI芯片独角兽Cerebras Systems宣布完成10亿美元（约合人民币69亿元）F轮融资，估值达到230亿美元（约合 人民币1596亿元）。 本轮融资由Tiger Global领投，Benchmark、Fidelity Management & Research Company、Atreides Management、Alpha Wave Global、Altimeter、 AMD、Coatue以及1789 Capital（合伙人包括小唐纳德·特朗普）等机构跟投。 成立于2015年的Cerebras，以餐盘大小的AI芯片而闻名。其晶圆级引擎3（WSE-3）芯片是全球最大、速度最快的AI芯片，体积是当前最大 GPU的56倍，单位计算功耗却远低于同类产品，同时推理和训练速度比竞品快20倍以上。 其芯片用于处理AI推理所需的顺序执行、内存密集型工作负载。与需要在芯片和内存之间来回传输数据的GPU不同，WSE将所有运算都保存 在芯片内部，从而消除了限制GPU推理能力的内存带宽瓶颈。 Cerebras上一轮融资是在2025年9月宣布完成的11亿美元（约合人民币76亿元）G轮融资，当时 ...
