Microsoft announced Monday it will deploy AMD Helios racks in its Azure data centers, joining other early customers Meta, OpenAI and Oracle.

Helios is AMD's first rack-scale system for AI and its most competitive move against Nvidia yet. It will ship later this year.

CNBC got an exclusive first detailed look inside AMD's new system at the Texas lab where it's being developed and tested.

Helios is AMD’s first AI system to rival Nvidia Vera Rubin — we got an exclusive, first look

After a decade-long comeback, chip giant Advanced Micro Devices is preparing to ship its first rack-scale system for artificial intelligence, called Helios, to a growing list of customers that now includes Microsoft.

It's the first rival to Nvidia's wildly popular Grace Blackwell and Vera Rubin systems, and is aiming to give the world's most valuable chipmaker its first real competition in years.

Microsoft announced Monday it will use the Helios system in its data centers, joining Meta, OpenAI, Oracle and others in a race to grab as much compute as possible.

AMD will begin shipping to customers, including Microsoft, later this year. Shares of AMD climbed more than 4% on Monday. Microsoft stock climbed more than 1%.

Details about financial terms or the amount of compute capacity weren't disclosed.

"We are expanding the Azure infrastructure portfolio with AMD Helios to give customers the performance, scale and choice they need to build and run the next generation of AI applications," Microsoft CEO Satya Nadella wrote in a press release.

The new Helios system will power frontier model inference for Microsoft, its AI customers and support Azure AI services. Microsoft will also add two new computing instances run on AMD's latest "Venice" central processing units, or CPUs, one for agentic AI and data pipelines, and another for semiconductor design.

It's the continuation of a longtime partnership, with AMD chips powering Microsoft's Surface PCs and Xbox gaming consoles for many years. In 2023, Microsoft was also the first to adopt AMD's MI300X graphics processing unit, or GPU, that rivaled Nvidia's AI chips. Microsoft also deploys its own Maia chips in its data centers.
