AMD Instinct MI400

AMD's next-generation Instinct MI400 AI accelerator is expected in 2026 using TSMC's 3nm process, targeting direct competition with NVIDIA's Blackwell architecture. With 192GB of HBM4 memory and ROCm software stack improvements bringing CUDA parity for the most common training frameworks, MI400 may be the first AMD GPU to win large-scale model training deployments from Tier 1 cloud providers.
