Microsoft Chooses AMD Helios for Azure Inference, Giving Nvidia Its First Rack-Scale Challenger

Microsoft will deploy AMD’s Helios rack-scale platform on Azure for production-scale frontier-model inference. Helios integrates MI455X GPUs, sixth-generation EPYC 'Venice' CPUs, Pensando networking and ROCm software; AMD says shipments to customers including Microsoft begin in the second half of 2026. Azure also announced HDv2 and HXv2 CPU VM families and broader Pensando deployment. CNBC estimated a Helios rack costs more than $5 million, while independent market coverage observed AMD shares rising about 5% after the announcement.
