AMD Unveils Instinct MI350 and MI400 Series GPUs, Previews Open-Standard Helios Rack Server

OpenAI commits to AMD’s MI400 chips ahead of Helios launching in 2026

Overview

  • The Instinct MI350 Series delivers four times the AI compute power and a 35-fold generational leap in inferencing over its predecessor.
  • AMD previewed the Instinct MI400 Series—which it says achieves up to 10× the MI300X’s performance—and plans to integrate it into the Helios rack-scale system in 2026.
  • Helios will feature open networking standards such as UALink and OCP compliance to rival Nvidia’s proprietary NVLink-powered NVL72 racks.
  • The upgraded ROCm7 software stack offers enhanced compatibility with industry-standard AI frameworks and improved performance for training and inference workloads.
  • AMD projects strong double-digit AI chip growth despite export controls and has secured deployments with OpenAI, Meta, Oracle, xAI and Cohere.
