让我们来看看Win32_Processor类的几个关键属性：
-
AddressWidth On a 32-bit operating system, the value is 32 and on a 64-bit operating system it is 64.
-
Architecture Processor architecture used by the platform.

-
NumberOfCores Number of cores for the current instance of the processor. A core is a physical processor on the integrated circuit. For example, in a dual-core processor this property has a value of 2.
-
NumberOfLogicalProcessors Number of logical processors for the current instance of the processor. For processors capable of hyperthreading, this value includes only the processors which have hyperthreading enabled.
DOS命令查看
C:\Users\xucy>wmic cpu get addresswidth,architecture,deviceid,name,numberofcores,numberoflogicalprocessors
AddressWidth Architecture DeviceID Name NumberOfCores NumberOfLogicalProcessors
64 9 CPU0 Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz 6 12
64 9 CPU1 Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz 6 12
PowerShell查看
PS C:\Users\xucy> Get-WmiObject -Class Win32_Processor | Format-Table -AutoSize AddressWidth,Architecture,DeviceId,Name,NumberOfCores,NumberOfLogicalProcessors
AddressWidth Architecture DeviceID Name NumberOfCores NumberOfLogicalProcessors
64 9 CPU0 Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz 6 12
64 9 CPU1 Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz 6 12
综上所述，我的CPU是双路六核开启超线程。
