Getting informationon installed CPUs, Cores and Sockets

A friend and former colleague asked me about a way to obtain rather detailed information on the type and number of CPUs installed in a server, as well as the number of cores present.
This is the function I came up with.

Please note that this function is incapable of coping nicely with limitations implemented using /NUMPROC in boot.ini
The function should work on Windows 2000 Server and above.


function GetCPUinfo {
    param ([array]$servernames = ".")
    foreach ($servername in $servernames) {
        [array]$wmiinfo = Get-WmiObject Win32_Processor -computer $servername
        $cpu = ($wmiinfo[0].name) -replace ' +', ' '
        $description = $wmiinfo[0].description
        $cores = ( $wmiinfo | Select SocketDesignation | Measure-Object ).count
        $sockets = ( $wmiinfo | Select SocketDesignation -unique | Measure-Object ).count
        Switch ($wmiinfo[0].architecture) {
            0 { $arch = "x86" }
            1 { $arch = "MIPS" }
            2 { $arch = "Alpha" }
            3 { $arch = "PowerPC" }
            6 { $arch = "Itanium" }
            9 { $arch = "x64" }
        }
        $manfg = $wmiinfo[0].manufacturer
        $obj = New-Object Object
        $obj | Add-Member Noteproperty Servername -value $servername
        $obj | Add-Member Noteproperty CPU -value $cpu
        $obj | Add-Member Noteproperty Description -value $description
        $obj | Add-Member Noteproperty Sockets -value $sockets
        $obj | Add-Member Noteproperty Cores -value $cores
        $obj | Add-Member Noteproperty Architecture -value $arch
        $obj | Add-Member Noteproperty Manufacturer -value $manfg
        $obj
    }
}

The function is invoked with a list of servers as the single parameter. If no parameter is specified, the local server "." is used.

$result = GetCPUinfo server1, server2, server3

The output can then be piped info a Format-Table or similar.

$result | format-table -auto

The result could look something like this:

Servername CPU                                   Description                         Sockets Cores Architecture Manufacturer
---------- ---                                   -----------                         ------- ----- ------------ ------------
server1    Intel(R) Xeon(TM) CPU 2.80GHz         EM64T Family 15 Model 4 Stepping 8        4    16 x64          GenuineIntel
server2    Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz EM64T Family 6 Model 15 Stepping 6        1     2 x64          GenuineIntel
server3    AMD Opteron(tm) Processor 285         AMD64 Family 15 Model 33 Stepping 2       2     2 x64          AuthenticAMD
server4    Intel(R) Xeon(R) CPU E7340 @ 2.40GHz  EM64T Family 6 Model 15 Stepping 8        2     2 x64          GenuineIntel
server5    Intel(R) Xeon(R) CPU E7340 @ 2.40GHz  EM64T Family 6 Model 15 Stepping 11       4    16 x64          GenuineIntel
server6    Intel(R) Xeon(TM) CPU 2.80GHz         x86 Family 15 Model 4 Stepping 8          1     1 x86          GenuineIntel
server7    Pentium III Tualatin                  x86 Family 6 Model 11 Stepping 1          2     2 x86          GenuineIntel
