AMD plans to launch its first two rack-scale Instinct accelerators in 2026 to compete with Nvidia's VR300 NVL144, reports SemiAnalysis. They are named AMD's Instinct MI450X IF64 and Instinct MI450X IF128, and both are designed for AI deployment. If they prove to be a success, it could change the landscape of AI hardware over time.
