Get CPU processor speed via PowerShell

I needed to get number of CPU processor speed as a number. I can't use any extra utility commands. I can use only cmd in Windows or Powershell.

wmic cpu get name | select -Skip 1 | %{$_.Split(' ')[5];} | %{$_.Substring(0, 3)}

Everything is performed correctly, except substring command enter image description here

Does it exist any easy approach to fix it? And why I get 4 warning for single value after split command?

Don't parse wmic output unless you're pressed for performance (and even then you should do (wmic cpu get maxclockspeed) -notlike '*maxclockspeed*' rather than parse the processor name output).

Use Get-WmiObject (all PowerShell versions) or Get-CimInstance (PowerShell v3 or newer) with the Win32_Processor class and expand the relevant property (MaxClockSpeed).

Get-CimInstance Win32_Processor | Select-Object -Expand MaxClockSpeed

The value is in MHz.
