> The 288-GB accelerator adds a memory-capacity option in AMD’s MI400 Series; AMD also plans an equity investment in PsiQuantum.

Advanced Micro Devices introduced the Instinct MI450X, a new AI GPU for data centers with 288 GB of HBM4, and expanded its PsiQuantum partnership to develop quantum-computing hardware.

The MI450X joins AMD’s MI400 Series for data-center and AI workloads. AMD says the GPU matches its MI455X in core compute, memory bandwidth and connectivity, while providing another memory-capacity configuration. AMD also said customers had asked for an AI GPU with less HBM4.

Under the expanded partnership, the companies will develop hardware for quantum computing. AMD plans to make an equity investment in PsiQuantum.
