AMD Positions Programmable AI NICs for Multiple Ethernet Transports

AMD is positioning its Pensando Pollara 400 and Vulcano 800 AI network interface cards as programmable platforms for adapting Ethernet transports as large AI clusters demand faster, more resilient accelerator-to-accelerator communication. The Pollara 400 uses a fully programmable hardware pipeline based on P4. That design supports RoCEv2, Ultra Ethernet Consortium (UEC) features and custom transport protocols without requiring a replacement networking platform. AMD lists speeds of up to 400 Gbps for the card. The architecture also includes packet spraying, selective retransmission, path-aware congestion control and rapid fault detection.
