Get Number Of Cores and Logical Processors information in SCCM

The default reporting in System Center Configuration Manager (SCCM) does not track the Number of Cores and Number of Logical Processors for each processor.The Win32_Processor WMI class contains number of cores (NumberOfCores) and logical processors (NumberOfLogicalProcessors) for each processor. It displays a unique DeviceID for each physical process in the system. This information is only available in newer version of OS's like Vista, Windows 7, Windows 2008, etc. For older version of OS like windows XP and Windows 2003 hotfix are available from Microsoft to populate this information in WMI. 

Windows XP SP2: http://support.microsoft.com/kb/936235

Windows 2003 SP1 or SP2: http://support.microsoft.com/kb/932370/en-us

The value for NumberOfLogicalProcessors will be higher than the value for NumberOfCores if the processor supports hyperthreading, which effectively splits a core into two logical processors. The challenge is that the reporting on Win32_Processor isn't enabled in the default sms_def.mof.

You can look at the information available in Win32_Processor WMI class using the following VB Script.

To enable this class reporting in SCCM, the guidelines to update sms_def.mof can be found at this MyITForum post. Aditional information about the Win32_Processors call can be found  here.
