About this tag
AMD Helios is a rack-scale AI server platform that pairs Instinct MI455X accelerators with sixth-generation EPYC Venice CPUs, Pensando networking, and ROCm software. Announced at AMD's Advancing AI 2026 event, Helios entered production with shipments expected in Q3 2026. The system offers up to 31TB of HBM4 memory and 2.9 exaFLOPS of FP4 compute, positioning it as a direct competitor to Nvidia's Vera Rubin NVL72. Microsoft plans to deploy Helios across Azure for frontier-model inference and AI services in the second half of 2026, marking a significant endorsement of AMD's full-stack approach in hyperscale AI infrastructure.
