在 CentOS 系统中,可以通过几种方法查看 CPU 型号:

  1. 使用 lscpu 命令

    lscpu
    

    输出中会包含 CPU 的型号信息。例如:

    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:               2800.000
    BogoMIPS:              5600.00
    Virtualization:        VT-x
    L1d cache:             32K
    L1i cache:             32K
    L2 cache:              256K
    L3 cache:              6144K
    
  2. 查看 /proc/cpuinfo 文件

    cat /proc/cpuinfo
    

    这个文件包含了详细的 CPU 信息。你可以查找 flagsmodel name 来识别 CPU 型号。例如:

    processor	: 0
    vendor_id	: GenuineIntel
    cpu family	: 6
    model		: 158
    model name	: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
    stepping	: 9
    microcode	: 0xea
    cpu MHz		: 2800.000
    cache size	: 6144 KB
    physical id	: 0
    siblings	: 8
    core id		: 0
    cpu cores	: 4
    apicid		: 0
    initial apicid	: 0
    fpu		: yes
    fpu_exception	: yes
    cpuid level	: 22
    wp		: yes
    flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch cpuid_fault epb invpcid_single pti ssbd ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid mpx rdseed adx smap clflushopt xsaveopt xsavec xgetbv1 xsaves dtherm ida arat pln pts hwp hwp_notify hwp_act_window hwp_epp md_clear flush_l1d

    bogomips	: 5600.00
    clflush size	: 64
    cache_alignment	: 64
    address sizes	: 39 bits physical, 48 bits virtual
    power management:
    
  3. 使用 dmidecode 命令

    sudo dmidecode -t processor
    

    输出中也会包含 CPU 的详细信息,包括型号名称。例如:

    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: 20 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
    	Status: Populated, Enabled
    	Upgrade: Other
    	L2 Cache: 256 KB
    	L3 Cache: 6144 KB
    

这些方法可以帮助你获取 CPU 的详细型号信息。
