IT之家 8 月 25 日消息,科技媒体 Wccftech 昨日(8 月 24 日)发布博文,报道称在 Hot Chips 2026 大会上,Arm 披露了面向智能体人工智能的 AGI CPU 细节,这是该公司成立 36 年以来首颗自研量产芯片

该处理器基于第 3 代 Neoverse V3 核心,基于 Armv9.2 架构,单颗芯片最多配置 136 个核心,每个核心配备 2 MB 专属 L2 缓存,最高频率为 3.7 GHz。

该芯片采用台积电 3nm 工艺(N3P)和双芯粒(Dual Chiplets)设计,每个芯粒搭载超过 500 亿个晶体管,完整芯片拥有 1,000 亿个晶体管,整颗芯片的最大 TDP 为 300 W。处理器将内存与 I/O 集成在同一芯片上,面向低延迟内存访问,内存延迟低于 100 ns。
