centos cpuinfo格式是什么

CentOS中CPU信息主要有两种查看方式及对应格式：

• cat /proc/cpuinfo命令：输出为键值对形式，每行一个字段，字段间用冒号分隔，示例：

  processor : 0
  vendor_id : GenuineIntel
  cpu family : 6
  model : 79
  model name : Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz
  stepping : 1
  cpu MHz : 4000.000
  cache size : 8192 KB
  physical id : 0
  siblings : 8
  core id : 0
  cpu cores : 8
  

• lscpu命令：输出为结构化格式，包含CPU架构、操作模式、核心数、线程数、缓存大小等信息，示例：

  Architecture: x86_64
