The Win32_Processor class does not distinguish among the following AMD families:

Athlon
Opteron
Sempron
Turion

After you apply this hotfix, all 64-bit AMD processors are identified by using a Family attribute value of 0x83 (131).

You can use the following Microsoft Visual Basic script to retrieve the Family attribute values of the processors that are installed on a computer.

set WMI = GetObject("winmgmts:\root\cimv2")
set colCPU = WMI.InstancesOf("Win32_Processor") 
for each objCPU in colCPU
	wscript.echo objCPU.DeviceID & " = " & objCPU.Family
