 # Graphics processing unit (GPU) virtual machine (VM) on Azure Stack Hub
 
-This article describes which graphics processing unit (GPU) models are supported on an Azure Stack Hub integrated system. You can also find instructions on installing the drivers used with the GPUs. GPU support in Azure Stack Hub enables solutions such as artificial intelligence, training, inference, and data visualization. The AMD Radeon Instinct MI25 can be used to support graphic-intensive applications such as Autodesk AutoCAD.

 ## Adding GPUs on an existing Azure Stack Hub
 
-Azure Stack Hub now supports adding GPUs to any existing system. To do this, execute stop-azurestack, run through the procedure of stop-azurestack, add GPUs, and then run **start-azurestack** until completion. If the system already had GPUs, then any previously created GPU VMs will need to be **stop-deallocated** and then **restarted**.
