**What’s the News?** Today at Advancing AI 2026, AMD launched **AMD Instinct™ MI400 Series GPUs**, the next generation of AMD data center GPUs engineered to redefine AI and high-performance computing (HPC) at every scale. The family includes the AMD Instinct™ MI455X GPUs for frontier AI and AI factory deployments and the AMD Instinct™ MI430X GPU for sovereign AI and HPC. The MI400 series combines leadership compute and networking performance, high-bandwidth HBM4 memory, advanced security and scalable system architectures to help organizations deploy, scale, and manage AI and HPC workloads with flexibility and confidence.

**Why It Matters?** AI infrastructure is becoming increasingly specialized as organizations deploy AI across a broader range of environments – from hyperscale AI factories focused on large-scale inference and frontier-model training to sovereign AI and scientific computing centers that demand numerical accuracy, security and long-term operational control. The AMD Instinct MI400 series provides purpose-built solutions for both environments, giving customers the flexibility to deploy optimized AI and HPC infrastructure while maintaining the openness, interoperability and software portability needed to scale future AI workloads.

**What’s the Role for AMD?**

> The next generation of AI will span frontier AI, sovereign AI and scientific computing, and each requires infrastructure optimized for its unique demands. The AMD Instinct MI400 Series extends our AI portfolio with purpose-built solutions optimized for the full spectrum of AI and HPC deployments, built on an open software foundation that gives customers the flexibility to innovate at every scale.

— Vamsi Boppana, senior vice president, AI, AMD

**What are AMD Instinct MI400 Series GPUs?** The AMD Instinct MI400 Series combines purpose-built hardware, open software and scalable system design to address the evolving needs of AI and HPC deployments. Key capabilities of the portfolio include:

- **Purpose-Built AI Infrastructure:** The AMD Instinct MI400 Series portfolio includes the AMD Helios™ rackscale solution powered by AMD Instinct MI455X GPUs for frontier AI and AI factory deployments alongside AMD Instinct MI430X GPUs for sovereign AI and HPC. Together, the portfolio provides purpose-built solutions optimized for hyperscale AI factories, national infrastructure, research institutions and leadership-class HPC environments.
- **Leadership Performance Across AI and HPC:** AMD Instinct MI455X GPUs deliver the compute, memory and networking performance required for high-volume inference, frontier-model training and fine-tuning. AMD Instinct MI430X GPUs deliver uncompromised accuracy and throughput across converged AI and HPC workflows with up to 288 TFLOPS of hardware-based FP64 performance for scientific computing. Across the portfolio, industry-leading HBM4 memory and high memory bandwidth help customers support larger models, reduce infrastructure complexity and improve efficiency at scale.
- **Open Software Foundation:** Powered by AMD ROCm™ software, the MI400 Series provides an open software foundation with programming models, compilers, libraries, runtimes and deployment tools for AI and HPC. This commitment to open standards supports interoperability and long-term portability across software, system and networking choices, helping customers innovate without vendor lock-in.
- **Secure and Scalable by Design:** AMD Instinct MI400 Series GPUs incorporate advanced security capabilities, secure boot, encrypted GPU-to-GPU links and hardware-based protections to help safeguard sensitive AI and HPC workloads. Combined with scalable system architectures – from the AMD Helios rackscale solution for frontier AI to traditional mesh-based HPC deployments – AMD Instinct MI400 series GPUs enable customers to deploy AI infrastructure with flexibility, confidence and long-term operational consistency.
