The article below show how to check system Processor Type (CPU Type) without open the computer casing on Linux Fedora using Linux dmidecode command. The step by step, Linux command example below show the Linux dmidecode command is execute to show processor type and the properties of Processor type inside the computer.
Linux command example:
/usr/sbin/dmidecode --type processor
or same as
dmidecode --type 4
The dmidecode --type processor could give the output on:
4 Processor
The output of dmidecode command below show, CPU Type (Processor type), CPU Family (Processor Family), CPU Manufacturer (Processor Manufacturer) and other Processor information or CPU information,
[root@localhost ~]# dmidecode --type processor
# dmidecode 2.7
SMBIOS 2.1 present.
Handle 0x0400, DMI type 4, 32 bytes.
