    Astera Labs 发布 Scorpio X PCIe 6.0 交换芯片,面向机架级 AI 系统

    Astera Labs 发布代号 Scorpio X 的 AI fabric 交换芯片,单颗 ASIC 集成 320 条 PCIe 6.0 通道,双向带宽 5.12 TB/s,可与几乎任何加速器配合使用。该芯片内置类似 NVSwitch 的网络内计算能力,并针对 MoE 推理推出名为 Hypercast 的多播操作,以减少 GPU 等待网络的时间。Scorpio X 系列与扩展至 32 至 320 通道的 Scorpio P 系列交换芯片目前处于送样阶段,量产预计在 2026 年下半年启动。

    switches have been used in a variety of applications including scale-out compute fabrics. CPUs alone either didn't offer enough or fast enough lanes for all the GPUs, NICs, and storage required. So, rather than hanging everything off the CPU, a PCIe switch, often built into the NIC, was used to connect everything together. Astera contends that with a big enough switch, PCIe is a viable alternative to interconnects like NVLink, in the scale-up fabrics used to make dozens or more GPUs behave more
