lscpu

lscpu is a simple shell command from the util-linux package which gathers information about a systems CPU from Linux's sysfs, /proc/cpuinfo and other available sources and presents that information in a nice overview.

lscpu will, without any command-line options, show you CPU architecture, the number of CPU cores, min and max frequencies, available CPU instructions (lscpu calls them flags) and known CPU vulnerabilities.

An example of lspcis output when it is executed with no arguments.

lspci has some command-line options which may be specially useful on dual-socket or many-socket systems. -b or --online will limit it's output to online CPUs and -c or --offline limit's it's output to offline CPUs.

The lscpu manual and lspcu -h will show you all the available switches.

It is about time that intel fixes the core meltdown of their processors. Even the Fukushima guys have fixed their reactor core meltdown by now.
