It uses Windows Management Instrumentation (WMI) to query installed video controllers and verify their memory capacity. This check is essential for AI workloads that require significant GPU memory. .OUTPUTS [bool] Returns true if a capable GPU is found, false otherwise. .EXAMPLE $hasGpu = Get-HasCapableGpu Write-Host "System has capable GPU: $hasGpu" #> function Get-HasCapableGpu { [CmdletBinding()] [OutputType([bool])] param() begin { # inform user that gpu check is starting Microsoft.PowerShell.Utility\Write-Verbose 'Starting GPU capability verification' } process { # define minimum required gpu memory (4GB in bytes) $requiredMemory = 1024 * 1024 * 1024 * 4 # query system for video controllers meeting memory requirement $videoControllers = CimCmdlets\Get-CimInstance ` -Class Win32_VideoController | Microsoft.PowerShell.Core\Where-Object { $_.AdapterRAM -ge $requiredMemory } # output number of capable gpus found for debugging Microsoft.PowerShell.Utility\Write-Verbose "Detected $($videoControllers.Count) GPUs with 4GB+ RAM" # return true if at least one capable gpu was found return $null -ne $videoControllers } end { } } |
