Getting Processor Information
Solution 1
It's often overlooked, so worth a shot. Sorry if this is insultingly obvious :
Alt-F2, then gnome-system-monitor
Also, when I ran sudo lshw | grep -i cpu
, I see a line which says cpus=2.
Solution 2
To get the Processor model use the below command in a terminal.
cat /proc/cpuinfo | grep 'name'| uniq
To get the information about number of processors
cat /proc/cpuinfo | grep process| wc -l
Solution 3
The simplest way to do this is to use the command created for that, lscpu
:
user@host:~$ lscpu
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 2
On-line CPU(s) list: 0,1
Thread(s) per core: 1
Core(s) per socket: 2
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 55
Model name: Intel(R) Celeron(R) CPU N2840 @ 2.16GHz
Stepping: 8
CPU MHz: 697.301
CPU max MHz: 2582,3000
CPU min MHz: 499,8000
BogoMIPS: 4331.60
Virtualization: VT-x
L1d cache: 24K
L1i cache: 32K
L2 cache: 1024K
NUMA node0 CPU(s): 0,1
Flags: fpu vme de pse tsc msr pae mce cx8 apic sep
mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm
pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl
xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor
ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 movbe popcnt
tsc_deadline_timer rdrand lahf_lm 3dnowprefetch epb tpr_shadow vnmi
flexpriority ept vpid tsc_adjust smep erms dtherm ida arat
This command will tell you your chipset's characteristics as well as any supported instructions (or flags) in an easy-to-use and simple-to-read manner.
Solution 4
In ubuntu 14.04 desktop, the system monitor tool no longer has a "System" tab. You should see roughly the same screen like this:
- click the settings wheel (to clarify: the taskbar icon in the absolute upper-right hand corner of the screen: )
- choose "About this Computer"
Solution 5
You can just use this : more /proc/cpuinfo
in your command line.
Then you faced with something like this :
You can use this for more information :

Toby over 1 year
I have just ran
lshw
to get some information about a machine I know nothing about, and I just wanted to confirm something.Does this basically mean it is a dual core 64 bit processor that is installed?
*-logicalcpu:0 description: Logical CPU physical id: 0.1 width: 64 bits capabilities: logical *-logicalcpu:1 description: Logical CPU physical id: 0.2 width: 64 bits capabilities: logical
Looking further down I see this
*-cpu:1 physical id: 1 bus info: cpu@1 version: 6.7.6 serial: 0001-0676-0000-0000-0000-0000 size: 3150MHz capabilities: vmx ht configuration: id=0 *-logicalcpu:0 description: Logical CPU physical id: 0.1 capabilities: logical *-logicalcpu:1 description: Logical CPU physical id: 0.2 capabilities: logical
Which makes me almost certain it is dual core but not convinced on the 64 bit.
Any help for this n00b would be greatly appreciated!
-
Scaine about 13 yearsMight be wrong, but that looks more like a single core doing hyperthreading, which presents two "logical cores".
-
Toby about 13 years@Scaine Do you know if there is a way to confirm that?
-
Scaine about 13 yearsI'm no expert on lshw, Toby, sorry. I've amended my answer to reflect the output from my core2Duo processor (no hyperthreading). Hope this helps.
-
Charlie Parker over 4 yearswhat about a single command in the terminal?
-
-
Toby about 13 yearsHa, thanks - that was overlooked! That has listed two processors both Core 2 Duos @3.16GHz. What it doesn't do it confirm if this is a 64 bit machine or not.. (or am I being dense and that fact is staring me in the face?)
-
Scaine about 13 years
uname -r
should help with that, surely? Or the same screenshot shows that I'm running 32-bit (my kernel is "generic"). -
Toby about 13 yearsI didn't set up the machine in the first place and I think the person who did erred on the site of caution and may have went for generic when they could have went higher. Thanks so much for your help. I have all the information I need now!
-
Lekensteyn about 13 yearsActually,
uname -m
tells you whether the OS is 64 bits or not. On a 64-bits machine, it returnsx86_64
. -
Scaine about 13 yearsI'd stick with generic myself, Toby. Arguments for both sides... AGAINST : blog.pault.ag/post/3107062816/… and FOR : jldugger.livejournal.com/41896.html. Unless you're a developer or heavy power user video editor type thingymajig... 32-bit is fine for a while longer.
-
Scaine about 13 years@Lekensteyn : Never knew that! You learn something new every day!
-
Lekensteyn about 13 years@Scaine: 64 bits vs 32 bits is an off-topic discussion here. 64 bits applications cannot run on a 32 bits OS, but the reverse is possible. As 64 bits is the future (even if it is available since 2000), I'll stick to an 64 bits OS and recommend others 64 bits as well.
-
Scaine about 13 yearsHorses for courses. I'm with you actually - the next build I do will be 64-bit, but all I'm saying is that 32-bit is still very much alive and kicking. But you're quite right. This is OT. :-)
-
Kees Cook about 13 yearsIf you stick with 32bit, at least use the -generic-pae kernel so you can get access to all your memory and gain the NX bit for security.

Dennis Golomazov almost 9 yearsSorry, what is the 'settings wheel'?

Ryan almost 9 years@DenisGolomazov - sorry, i just edited the answer to explain
-
WinEunuuchs2Unix about 7 yearsThose commands output "x86_64" which identifies that 64-bit software is being used. However, it doesn't answer question of whether or not there is a dual core processor. Using
sudo lshw -class CPU
will provide model number of processor which can be googled to get full specifications of that chip which could be single core, hyper-threaded. -
Kaz Wolfe about 7 yearsNote, though, that with this result, your system will not output
x86_64
if you do not have the 64-bit kernel installed on your system. -
Batwoman05 about 7 yearsThank you @KazWolfe for the edit. I was searching for this answer to run some Benchmarking suites on different processors, and came across these commands.

stdunbar over 4 yearsFor future Googlers - this command doesn't work on ARM processors as the output is very different in at least 18.04. The
lscpu
command below works well. -

grep
could handle files as well as stdout, so you could simplify it like this:grep name /proc/cpuinfo | uniq
