乐恒分享

  怎么看电脑cpu信息,以及判断cpu的性能,查看cpu的方法有很多,并且非常的简单,但还是有很多新手不知道怎么做,为此学习啦小编为大家整理推荐了相关的知识,希望大家喜欢。

  linux查看cpu的信息的方法

  1 查看CPU

  1.1 查看CPU个数

  # cat /proc/cpuinfo | grep "physical id" | uniq | wc -l

  2

  **uniq命令:删除重复行;wc –l命令:统计行数**

  1.2 查看CPU核数

  # cat /proc/cpuinfo | grep "cpu cores" | uniq

  cpu cores : 4

  1.3 查看CPU型号

  # cat /proc/cpuinfo | grep 'model name' |uniq

  model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

  总结:该服务器有2个4核CPU,型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

  2 查看内存

  2.1 查看内存总数

  #cat /proc/meminfo | grep MemTotal

  MemTotal: 32941268 kB //内存32G

  2.2 查看内存条数
