ubuntu - 了解 CPU 架构缩写

Question

我已经在电脑上安装了ubuntu。现在我想知道它的CPU架构。我读过 uname -a 可以用于此目的，因此:

~$ uname -a
Linux desknode1 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

从此页面:

http://en.wikipedia.org/wiki/X86-64

我推断它是 AMD cpu。但如果我运行:

~$ grep --color "model name" /proc/cpuinfo
model name  : Intel(R) Xeon(R) CPU           E5430  @ 2.66GHz
model name  : Intel(R) Xeon(R) CPU           E5430  @ 2.66GHz
model name  : Intel(R) Xeon(R) CPU           E5430  @ 2.66GHz
model name  : Intel(R) Xeon(R) CPU           E5430  @ 2.66GHz
~$ 

表明它是英特尔四核。我还尝试运行 lscpu :

$ lscpu

: 供应商 ID:GenuineIntel

表示 Intel CPU。那么这台机器上的CPU是什么？

Answer 1

“uname -a”仅显示编译内核的架构。例如，在64位cpu(/proc/cpuinfo)上使用32位内核(uname)没有问题。
