公众号记得加星标⭐️，第一时间看推送不会错过。 HBF采用多层3D NAND芯片堆叠技术，与HBM互补，用于GPU。 人工智能工作负载的爆炸式增长给内存系统带来了前所未有的压力，迫使企业重新思考如何向加速器 提供数据。 高带宽内存 (HBM) 已用作 GPU 的快速缓存，使AI 工具能够高效地读取和处理键值 (KV) 数据。 然而，HBM 价格昂贵、速度快、容量有限，而高带宽闪存 (HBF) 则以较慢的速度提供更大的容量。 HBF 如何与 HBM 互补 HBF 的设计允许GPU访问更广泛的数据集，同时限制写入次数（每个模块大约 100,000 次），这就 需要软件优先处理读取操作而不是写入操作。 HBF 将与 HBM 集成到 AI 加速器附近，形成分层内存架构。 韩国科学技术院 (KAIST) 的金钟浩教授将 HBM 比作家里的书架，方便快速学习；而 HBF 则像一 个图书馆，内容更丰富，但访问速度较慢。 该概念设想未来的迭代产品（如 HBM7）可以作为"内存工厂"运行，数据可以直接从 HBF 进行处 理，而无需通过传统的存储网络。 HBF 将多个 3D NAND 芯片垂直堆叠，类似于 HBM 将 DRAM ...

18A良率仍是关键 从业务结构看，英特尔2025财年第四财季呈现出"核心增长、基础承压"的分化特征。 增长动力主要来自数据中心与人工智能（DCAI）业务。该板块在第四财季的营收达47.4亿美元，同比 增长9%，超过44.2亿美元的市场预期，环比增幅达到15%。Granite Rapids、Sapphire Rapids等服务器芯 片需求强劲，叠加与英伟达合作定制Xeon+NVLink芯片的协同效应，成为财报最大亮点。 凯投银行在研报中明确指出，超大规模云服务商对数据中心的强劲需求，将持续为DCAI业务提供增长 支撑，并将英特尔评级从"行业标配"上调至"增持"，目标价60美元/股。 造成第四财季营收同比下滑的核心因素是客户端计算组（CCG）业务，该板块全年营收322亿美元，同 比下降3%。一方面，受PC市场整体复苏乏力影响；另一方面，外界认为是英特尔自身产能错配——此 前将产能向新一代Gen6 CPU倾斜，却未能匹配市场对成熟Gen4、Gen5产品的需求，导致部分订单流 失。此外，18A先进制程良率虽每月提升，但尚未达到行业领先水平，新增产能释放缓慢，进一步制约 了整体营收规模。 2026年1月23日，英特尔（ ...
