消息面上，国内CPU龙头企业受益于海外高端CPU涨价趋势。据KeyBanc，Intel和AMD在2026年的服务 器CPU产能已被锁定大部分，计划在一季度提价10%-15%。 业内指出，需求端看，AI推理需要CPU总管，推理规模越大，CPU 就很容易成为瓶颈。以AI Agent为 例，一次"用户请求"会触发多次模型调用、工具调用、检索等功能，还要做计划、反思、回滚、权限、 状态持久化。CPU 在"控制面 + 数据面"的占比变大，尤其影响尾延迟与吞吐稳定性。供给端看，先进 制程与先进封装等关键资源扩张节奏慢，GPU等芯片过去挤压了CPU可得性、拉长交期，强化了CPU核 心厂商提价能力。 此外，韩国两大存储芯片巨头三星电子和SK海力士据报将继续削减NAND闪存产量，或加剧供应短缺 情况。美光科技近日表示，过去一个季度内存芯片短缺的情况愈演愈烈，并重申由于人工智能基础设施 所需的高端半导体需求激增，这种短缺状况将持续到今年以后。 格隆汇1月21日｜A股主要指数上涨，芯片股领涨，龙芯中科20CM涨停，海光信息涨超12%，带动科创 芯片设计ETF易方达(589030)大涨4.17%。 华福证券认为，存储供需矛盾有望触发 ...
