10 月 29 日消息，在今日举行的 NVIDIA GTC 2025 年 10 月大会（GTC DC）上，英伟达发布了多项重磅新品，其中一项尤为引人注目：下一代 NVIDIA BlueField-4 DPU 不仅将支持 800G 高速网络和 NVIDIA ConnectX-9 网络技术，还将集成多达 64 个 Arm 核心。IT之家注意到，英伟达尚未披露 BlueField-4 DPU 完整的规格参数，但已确认新款 NVIDIA BlueField-4 DPU 集成了高达 1260 亿个晶体管，并将搭配 NVIDIA ConnectX-9 网络技术，全面支持 800G 网络连接能力。最引人关注的是，这款新型 DPU 将配备一个拥有 64 个核心的“Grace”CPU。这一设计颇具深意，因为英伟达此前已将其 Grace 架构应用于当前一代基于 Arm Neoverse V2 的处理器，以及 GB10 平台中 —— 后者同时集成了两种不同类型的 Arm Cortex 核心。鉴于 BlueField-4 属于 Rubin 架构产品线并计划于 2026 年面世，业界普遍预期该芯片至少将支持 PCIe Gen6 接口标准。根据英伟达官方声明：“NVIDIA BlueField-4 预计将作为 NVIDIA Vera Rubin 平台的一部分，于 2026 年初进入早期可用阶段。”在发布会上，英伟达 CEO 黄仁勋（Jensen Huang）指出，新一代网卡（NIC）的关键驱动力之一，是加速其系统中的 KV 缓存（Key-Value Cache）处理能力。虽然 NVIDIA Rubin CPX 更侧重于预填充（prefill）阶段的性能优化，但 KV 缓存在诸如恢复与大语言模型（LLM）的历史对话等场景中发挥着关键作用。对于整个网络生态系统而言，这一产品意义重大。英伟达的战略始终是通过打造更大、更强大的芯片，集成更多功能，以提升 AI 工厂的运行效率。尽管 BlueField-4 并非市场上首款采用 64 核 Arm 架构的 DPU，但由英伟达推出的这一产品仍将对行业产生深远影响，尤其是在当前全球大量资本支出（CapEx）持续投向基于英伟达 GPU 的 AI 集群背景下，其生态主导地位愈发凸显。广告声明：文内含有的对外跳转链接（包括不限于超链接、二维码、口令等形式），用于传递更多信息，节省甄选时间，结果仅供参考，IT之家所有文章均包含本声明。","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"1","news_tag":"productRelease","news_rank":0,"symbols":[],"gpt_button":0,"need_auth":false,"code":"91000000","status":"200"}}}
