This article introduces a hardware-centric definition of compute cluster bisection bandwidth as a performance metric for AI-scale 448 Gbps systems. Unlike traditional abstractions, this metric is grounded in physical interconnect layout and IO port availability, enabling system architects to evaluate bandwidth provisioning through real, bidirectional link paths.
Infineon supports the 800 VDC power architecture announced by NVIDIA at Computex 2025 for AI infrastructure. A shift to a centralized 800 VDC architecture allows for reduced power losses, higher efficiency and reliability. However, the new architecture requires new power conversion solutions and safety mechanisms to prevent potential hazards and costly server downtimes.
With the expansion of its power protection portfolio Infineon supports the growing requirements for power path protection solutions for current and future high-power AI server ecosystems ranging from 48 V to +/-400 V and 800 V.
