>Model name: Intel(R) Core(TM) i5-8350U CPU 1. The information will display details like threads,sockets,NUMA (Non-Uniform Memory Access),information about caches and cache sharing,model, bogoMIPS, stepping and byte order. Lscpu fetches the details of system architecture details from sysfs and /proc/cpuinfo.
LSCPU method to get CPU information in Linux:
Apicid:ĭenotes the number of virtual as given by bios. Shows number of processors attached to the same physical processor. Stands for floating point unit.It’s a part of processor used for floating point calculations. Tells us the size of temporary storage area that the computer’s processor can retrieve data in much faster way. Core Id:ĭenotes the number of cores (here we have cores 0-3 i.e. lscpu displays some advanced information about your CPU: linux. In other words, dmidecode acts as a decoder of the DMI table.
#Linux cpuinfo command serial#
Here processor 0 is on core- 0 and processor 7 is on core-3 (see line core_id). uname -p displays the CPU architecture: linux uname command. What is the dmidecode Command in Linux Dmidecode reads the data from DMI (Desktop Management Interface) table, which holds information for the system’s hardware components like BIOS Revision, Serial Number, RAM, CPU, manufacturer information, etc. In case of multiple processors, it will display them sequentially starting from 0. This will display the number of processors on the machine. Let us discuss few important terminology in detail for linux cpu info as below: Processor:
