windows下查看cpu的物理个数、核数和线程数

总核数 = 物理CPU个数 X 每颗物理CPU的核数
总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

如果在bios关闭超线程，那么
总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 1

任务管理器也可看：

###1、查看物理CPU的个数
在cmd命令中输入“systeminfo”，以下信息表示物理CPU有一个

###2、查看物理CPU数、CPU核心数、线程数
在cmd命令中输入“wmic”，然后在出现的新窗口中输入“cpu get *”。
NumberOfCores：表示CPU核心数
NumberOfLogicalProcessors：表示CPU线程数
