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!

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

The simplest way to do this is to use the command created for that, lscpu:

user@host:~$ lscpu

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.

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.

In ubuntu 14.04 desktop, the system monitor tool no longer has a "System" tab. You should see roughly the same screen like this:

1. click the settings wheel (to clarify: the taskbar icon in the absolute upper-right hand corner of the screen: )
2. choose "About this Computer"

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 :

Use the uname -m or arch command from the terminal.

For a 64-bit processor and kernel, the command will output x86_64.

The Hardware Lister application (lshw-gtk) from the default Ubuntu repositories is a user-friendly GUI application that displays detailed information about your computer's hardware including the model name and architecture (32-bit or 64-bit) of the CPU.

Simply select a category to obtain detailed information about a hardware component from the main interface.

The simplest way is from Launcher select System Settings-->Details:

This identifies both your CPU model number and whether 32-bit or 64-bit software is running. It also displays other useful information such as amount of RAM.

Now take your CPU model number in google search engine type 3630QM number of cores:

Replace 3630QM with the model number you get from the first display.

All the other answers are great answers but if you really want the "simplest" way of doing this I believe this is the preferred method without opening a terminal session or installing new software.
