The new unit is the AMD Pensando Pollara 400, which promises an up to six times performance boost for AI workloads. The AMD Pensando Pollara 400 is a 400 GbE Ultra Ethernet card based on a processor designed by the company's Pensando unit. The network processor features a processor with a programmable hardware pipeline, programmable RDMA transport, programmable congestion control, and communication library acceleration. The NIC will sample in the fourth quarter and will be commercially available in the first half of 2025, just after the Ultra Ethernet Consortium formally publishes the UEC 1.0 specification. The AMD Pensando Pollara 400 AI NIC is designed to optimize AI and HPC networking through several advanced capabilities. One of its key features is intelligent multipathing, which dynamically distributes data packets across optimal routes, preventing network congestion and improving overall efficiency. The NIC also includes path-aware congestion control, which reroutes data away from temporarily congested paths to ensure continuous high-speed data flow. https://www.tomshardware.com/networking/amd-unveils-industrys-first-ultra-ethernet-ready-network-card-for-ai-and-hpc -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
