AMD debuts a 400GbE AI network card with an 800GbE PCIe Gen6 NIC coming in 2026, but will the industry be ready?

• AMD ships Pollara 400 AI NIC for open high-speed AI networking
• Supports Ultra Ethernet standard with RDMA and RCCL for efficient communication
• Future Vulcano 800G AI NIC targets PCIe Gen6 and rack-scale GPU clusters

AMD has begun shipping the Pensando Pollara 400 AI network card, part of the company's push for open, high-speed data center networking.

Designed for PCIe Gen5 systems, the card supports the Ultra Ethernet Consortium (UEC) standard, which aims to transform Ethernet for AI and HPC at scale.

The card offers RDMA support and is optimized for scale-out collective communication using RCCL, AMD’s alternative to NCCL.
