Getting look into what CPU you’re running is a useful to know.
Sometimes, you need to know information about the CPU on your machine, what kind of CPU your computer has or you need a full details, how many number of cores there or it’s 32- or 64-bit. Here are the ways to get detail information about CPU on linux.
Step 1 : Lets look at lscpu command:
A command-line utility “lscpu” in Linux is used to get CPU information of the system. The “lscpu” command fetches the CPU architecture information.
#lscpu
Step 2 : Check /proc/cpuinfo file
There is alternate way also to ge the information about the system architecture, the “/proc/cpuinfo” file also indicates the number of cores, you can open and the check file with “cat” command.
#cat/proc/cpuinfo
Step 3 : Lets check architecture of the machine:
If you want to know the architecture of the CPU, you use the “arch” command.
#arch
Step 4 : Now lets check model of your CPU with the processor:
#uname – processor
5. Using dmidecode for Hardware Details
dmidecode provides in-depth hardware information, including the CPU serial number:
sudo dmidecode -t processor
6. Using GUI Tools (Optional)
If you prefer a GUI-based approach, use tools like Hardinfo or Sysinfo:
sudo apt install hardinfo
FAQs
1. What is the difference between lscpu and /proc/cpuinfo?
lscpu provides a summary of system-wide CPU details, while /proc/cpuinfo gives core-specific information.
2. How can I check if my CPU supports virtualization?
Run the following command:
lscpu | grep Virtualization
Look for “VT-x” (Intel) or “AMD-V” (AMD) in the flags.
3. Can I monitor real-time CPU performance?
Yes, tools like top, htop, and mpstat allow you to monitor CPU performance in real-time.
4. How do I check the CPU temperature?
Install and use the lm-sensors package:
sudo apt install lm-sensors
5. Is there a way to benchmark my CPU?
Yes, tools like sysbench or the Phoronix Test Suite can benchmark your CPU.
6. How do I check the number of cores and threads?
Use the lscpu command or inspect /proc/cpuinfo for detailed information.
7. What is the best way to monitor CPU performance?
Use tools such as htop, mpstat, or graphical alternatives like Hardinfo for detailed monitoring.
