linux怎么查看cpu的信息
怎么看電腦cpu信息，以及判斷cpu的性能,查看cpu的方法有很多，并且非常的簡單，但還是有很多新手不知道怎么做，為此學(xué)習(xí)啦小編為大家整理推薦了相關(guān)的知識，希望大家喜歡。
linux查看cpu的信息的方法
1 查看CPU
1.1 查看CPU個數(shù)
# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2
**uniq命令：刪除重復(fù)行;wc –l命令：統(tǒng)計行數(shù)**
1.2 查看CPU核數(shù)
# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 4
1.3 查看CPU型號
# cat /proc/cpuinfo | grep 'model name' |uniq
model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
總結(jié)：該服務(wù)器有2個4核CPU，型號Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
2 查看內(nèi)存
2.1 查看內(nèi)存總數(shù)
#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //內(nèi)存32G
2.2 查看內(nèi)存條數(shù)
