Getting CPU Information

To display details about your CPU architecture, you can use the lscpu command. This will show information like:

• Number of CPU cores
• CPU model name
• Supported instruction sets
• CPU frequency
• Cache sizes

For example:

lscpu

Architecture:        x86_64
CPU op-mode(s):      32-bit, 64-bit
Byte Order:          Little Endian
CPU(s):              8
Model name:          Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
CPU MHz:             800.084
Cache size:          6 MB
