AMD Helios AI System to Power Microsoft Azure as TSMC Expands Arizona Chip Investment

AMD announced an expanded strategic partnership with Microsoft, under which the tech giant will deploy AMD’s next‑generation Helios rack‑scale AI platform on Azure. The Helios system integrates Instinct MI455X GPUs, 6th‑gen EPYC “Venice” CPUs, Pensando DPUs and ROCm software, and shipments to Microsoft and other customers are scheduled for the second half of 2026. Microsoft will launch three new Azure VM families – HDv2 for data processing, HXv2 for semiconductor design, and ND MI455X v7 for AI inference – all powered by the Helios stack. The collaboration broadens Azure’s AI infrastructure and gives customers additional high‑performance compute options.

Separately, Taiwan Semiconductor Manufacturing Co. (TSMC) said it will add a further US$100 billion to its Arizona expansion, raising its total U.S. investment to roughly US$2.65 trillion. The additional funding will support up to ten new fabs, advanced packaging facilities, and an R&D centre, aiming to meet what the company describes as “strong, multi‑year structural demand” for AI chips. CFO Wendell Huang cited robust customer demand and U.S. government support, noting that the expanded capex will lift TSMC’s annual spending outlook to $600‑$640 billion. The Arizona sites are already delivering yields comparable to TSMC’s flagship Taiwan fab, though the company acknowledges labor and construction constraints.
