Nordic manufacturer s 800G AI server

The 800G AI server leverages high-bandwidth 800G Ethernet, low-latency switching, and advanced 800V power architectures to support large-scale AI workloads efficiently.Networking and PerformanceModern 800G AI servers are designed to handle massive AI datasets and high-performance computing (HPC) workloads. They utilize 800G Ethernet, which doubles the throughput of 400G Ethernet, providing 800 Gbps per port through eight parallel lanes at 100 Gbps each, with advanced Forward Error Correction (FEC) and Media Access Control (MAC) for reliable, low-latency transmission . This enables seamless data movement across GPU clusters, reducing AI training iteration times and alleviating network bottlenecks in hyperscale data centers . Some 800G AI switches, like Asterfusion's CX-N series, offer 64 x 800G ports with total switching capacities up to 51.2 Tbps and port-to-port latencies as low as ~400 ns, ideal for latency-sensitive AI workloads .Power ArchitectureHigh-performance AI servers require robust power delivery. Infineon Technologies, in collaboration with NVIDIA, is pioneering 800V high-voltage direct current (HVDC) architectures for AI data centers . This centralized power system reduces losses, improves efficiency, and allows direct power conversion at the GPU, supporting racks with power outputs exceeding 1 MW per IT rack before 2030 . The architecture uses advanced semiconductor materials like silicon carbide (SiC) and gallium nitride (GaN) to accelerate development cycles and ensure reliability .
