Introducing AMD CDNA™ 5 and the AMD Helios™ Rackscale Solution
- 04 August 2026
AI infrastructure is being redefined at the scale of the entire rack. This blog will walk you through how the AMD CDNA™ 5 architecture, the AMD Instinct™ MI455X GPU, and the AMD Helios rackscale solution come together as a single open platform for large-scale AI training and inference. You will see how AMD balances compute, memory, and networking across 72 GPUs, how open standards keep the platform flexible, and how the AMD ROCm™ software stack ties it all into a complete, deployable system, from silicon to rack. By the end, you will understand what changes when AI infrastructure is designed as a unified rack rather than a collection of discrete GPU servers, and where AMD is taking it next.
