AMD Instinct MI450X

Announced

Helios GPU introduced by AMD on Nov. 12, 2026 with 288 GB of HBM4. AMD says it has the same core compute, memory bandwidth, and scale-up and scale-out connectivity as the MI455X, which the company says offers more memory for larger models, longer contexts, or higher concurrency. The product page lists CDNA 5, a TSMC 2 nm and 3 nm process, 23.3 TB/s peak memory bandwidth, 40.3 PFLOPs peak OCP MXFP4, 3.6 TB/s UALoE scale-up, 600 GB/s UALink scale-out, and direct liquid cooling.
