Vulnerability Itlb multihit: KVM: Mitigation: VMX unsupported Model name: Intel(R) Core(TM) i5-7360U CPU 2.30GHz Simply run: lscpuĪnd you’ll get output that looks something like this: Architecture: x86_64Īddress sizes: 36 bits physical, 48 bits virtual The lscpu command can also be used to display information about your CPU. The -m 1 option supplied to grep will return only the model of one of the CPUs – otherwise, you’ll get the model for each core on a multi-core CPU, and it’s almost certain that they will be the same. Which will output something like: model name : Intel(R) Core(TM) i5-7360U CPU 2.30GHz You probably only really want the model name of your CPU so you can compare it with others – you can limit this output by searching the output with the grep command: grep -m 1 'model name' /proc/cpuinfo My computer has two processor cores, so the information for the two processors is listed.

One of the core concepts which Linux (generally) adheres to is that all aspects of the computer system are represented in the filesystem – including hardware. The type of CPU, how old it is, and how fast it is determines how responsive your computer is and how quickly it can do things. The CPU (Central Processing Unit) in your computer does all of the number crunching and processing and logic that your computer needs to do to, well, compute.
