又一次巨大飞跃:NVIDIA Rubin CPX 专用加速器与机架
NVIDIA 推出面向推理 prefill 阶段的 Rubin CPX,以更高算力占比和低成本内存减少 HBM 与 NVLink 资源浪费。单芯片提供 20 PFLOPS 稠密 FP4 算力、128GB GDDR7 和 2TB/s 带宽,并通过 PCIe Gen 6 联网。该产品将用于固定配置的 VR200 NVL144 CPX 或更灵活的 Vera Rubin CPX 双机架方案。
able to the EFA NIC in the sidecar rack. MTIAv4’s SUE72 (featuring a 72-logical GPU with all to all switched scale-up size just like the VR200 NVL144) design similarly can lean on Meta internal inference workloads. Even emerging designs such as OpenAI’s chip with Broadcom stand to compete given they will be codesigned with Frontier Models in mind and with an internal workload as a backstop. Despite enjoying the benefit of internal demand, the MTIAv3 is excluded from this category due to its smal
