在 CentOS 系统中,你可以使用多种命令来获取 CPU 的详细信息。以下是一些常用的方法:

  1. lscpulscpu 命令可以显示 CPU 架构的信息。

    lscpu
    

    输出示例:

    Architecture:          x86_64
    CPU op-mode(s):        32-bit, 64-bit
    Byte Order:            Little Endian
    CPU(s):                4
    On-line CPU(s) list:   0-3
    Thread(s) per core:    1
    Core(s) per socket:    4
    Socket(s):             1
    NUMA node(s):          1
    Vendor ID:             GenuineIntel
    CPU family:            6
    Model:                 158
    Model name:            Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
    Stepping:              9
    CPU MHz:               2808.000
    BogoMIPS:              5616.00
    Virtualization:        VT-x
    L1d cache:             32K
    L1i cache:             32K
    L2 cache:              256K
    L3 cache:              6144K
    NUMA node0 CPU(s):     0-3
    
  2. cat /proc/cpuinfocat /proc/cpuinfo 命令会显示所有 CPU 核心的详细信息。

    cat /proc/cpuinfo
    

    输出示例(部分):

    vendor_id	: GenuineIntel
    cpu family	: 6
    model		: 158
    model name	: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz

  3. dmidecodedmidecode 是一个更全面的工具,可以显示硬件系统的详细信息,包括 CPU。

    sudo dmidecode -t processor
    

    输出示例(部分):

    Handle 0x001C, DMI type 4, 42 bytes
    Processor Information
    	Socket Designation: CPU1
    	Type: Central Processor
    	Family: Intel(R) Core(TM) i7-7700HQ Processor
    	Manufacturer: GenuineIntel
    	ID: 2C 06 03 00 FF FB EB BF
    	Version: Intel(R) Core(TM) i7-7700HQ Processor
    	Voltage: 1.2 V
    	External Clock: 100 MHz
    	Max Speed: 3800 MHz
    	Current Speed: 2800 MHz
