List CPU

Jan 2018

I am unsure if lscpu is installed by default, on the servers I have used so far it always seems to be there (even on my Raspberry Pi's).
To list the CPU(s) fitted to a Linux server, use the following:

lscpu

Here is the output from a server:

Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 48
On-line CPU(s) list: 0-47
Thread(s) per core: 2
Core(s) per socket: 12
Socket(s): 2
NUMA node(s): 2
Vendor ID: GenuineIntel
CPU family: 6
Model: 63
Stepping: 2
CPU MHz: 2501.000
BogoMIPS: 4988.08
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K

L3 cache: 30720K
NUMA node0 CPU(s): 0-11,24-35
NUMA node1 CPU(s): 12-23,36-47

Here is what it looks like on a Raspberry Pi v3

Architecture: armv7l
