Română(RO) PSA: DO NOT use Intel consumer platforms for multi-GPU setups

英特尔消费级平台因 PCIe P2P 问题阻碍多 GPU AI 设置

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-25 03:35

Reddit 的 r/LocalLLaMA 论坛上一位用户报告了在使用英特尔消费级平台（特别是配备 Arrow Lake CPU 的 Z890 主板）进行多 GPU 设置时遇到的重大问题。已识别出的主要问题是 GPU 之间 PCIe 点对点 (P2P) 通信失败，这对于 AI 推理和训练工作负载至关重要。尽管该平台提供 PCIe 5.0 通道，但 P2P 功能似乎受到硬件或固件限制的阻碍，导致在使用修补驱动程序尝试 P2P 时带宽急剧下降，甚至出现无意义的输出。 AI

影响可能阻碍用户在消费级英特尔硬件上构建多 GPU AI 推理系统。
