Modern day Linux also supports additional commands to determine the processor model

1. lscpu - gives a summary of the processor hardware

2. dmidecode - can display quite a bit of information about the total hardware. One can view the processor related information by searching for "Processor" section in the output. "cat  /proc/cpuinfo" mentioned in the previous post also presents similar info.
