ubuntu系统中怎么查看cpu型号和频率？

系统运维 2024-06-07 泡泡手机阅读

在Ubuntu上查看CPU型号和频率的方法有很多。以下是几种常用的方法：

1. 使用 lscpu 命令

lscpu 命令会显示有关CPU的信息，包括型号和频率。

lscpu

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: 2

Core(s) per socket: 2

Socket(s): 1

NUMA node(s): 1

Vendor ID: GenuineIntel

CPU family: 6

Model: 142

Model name: Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz

Stepping: 10

CPU MHz: 2112.004

CPU max MHz: 4200.0000

CPU min MHz: 400.0000

2. 查看 /proc/cpuinfo 文件

/proc/cpuinfo 文件包含有关CPU的详细信息。

cat /proc/cpuinfo

输出示例：

3. 使用 dmidecode 命令dmidecode 命令可以获取更多关于硬件的信息，包括CPU的型号和频率。

sudo dmidecode -t processor

输出示例：

# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
