Ubuntu CPU Info - How to Show Processor Information in Terminal

Let’s take a look at how we can view CPU info on Ubuntu Linux. There are a couple ways, one is to look at the /proc/cpuinfo.

Go to Ubuntu terminal and enter the following command:

cat /proc/cpuinfo

The Ubuntu kernel keeps information about your CPU in the /proc/cpuinfo file. When queried, it provides lots of information about the processor on your Ubuntu Computer.

From the preceding output, we can see /proc/cpuinfo file contains lots of information such as vendor_id, model name, cache size, the CPU rate in MHZ, and so on.

Viewing CPU info with lscpu command

The lscpu command on Ubuntu displays CPU information in a user-friendly way. Actually, it collects information from the /proc/cpuinfo file and presents it in a way that the user can understand easily.

lscpu 
Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                2
On-line CPU(s) list:   0,1
Thread(s) per core:    1
Core(s) per socket:    2
Socket(s):             1
NUMA node(s):          1
Vendor ID:             AuthenticAMD
CPU family:            20
Model:                 2
Model name:            AMD E-450 APU with Radeon(tm) HD Graphics
Stepping:              0
CPU MHz:               825.000
CPU max MHz:           1650.0000
CPU min MHz:           825.0000

L1i cache:             32K
L2 cache:              512K
NUMA node0 CPU(s):     0,1

Looking at the lscpu output, we can say that my Ubuntu machine has AMD dual-core processor.
