Similar to this question, I have a 32-bit OS (Ubuntu), but I want to know if my machine is 64-bit capable... I checked out the question, but the answers are Windows-specific... I also checked this question, but I want to know if it is 64-bit capable, I know my OS is 32-bit.
Thanks, whoever I am

  • usually the best bet is to look up your CPU model online. you can use lshw to tell you. – Frank Thomas Jun 18 '14 at 20:18
  • Please include the output of cat /proc/cpuinfo in your question. – Cristian Ciupitu Jun 18 '14 at 20:20

    lscpu should work as well . . . – ernie Jun 18 '14 at 20:21
  • Surely this is a duplicate question and has been asked many times. grep ' lm ' /proc/cpuinfo - no output = 32 bit processor. lm = long mode == 64 bit capable and is considered the most relilable flag. – Panther Jun 18 '14 at 21:11
  • How can I check if my CPU is AMD64 compatible? from Ask Ubuntu. – Cristian Ciupitu Jun 18 '14 at 21:40

If you have an Intel processor, they provide their own site with tons of information of each processor, called the Intel ARK. Just search for your processor there, and it will have a section called Intel 64, with either a yes or no box.

For AMD processors, here is a list of all their processors, and by pressing View Details you can see if it is 64-bit capable.

run (as root/sudo)

lshw -class CPU

and look at the Width attribute. If its 64bit, your hardware is capable.

    This should be accepted answer. – punund Dec 3 '14 at 20:02

Just to throw a revision of Frank Thomas's answer into the ring. Enter this into your terminal and the answer will be pretty obvious.

lshw -class CPU | grep -i "width"

The way I usually do it is by googling the cpu. You can pull the CPU from the BIOS and a look for the specs from Intel, Newegg, etc.
