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:
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 BogoMIPS: 3291.88 Virtualization: AMD-V L1d cache: 32K 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.
