How can I check if my CPU is AMD64 compatible?

I am currently under Ubuntu 12.04 LTS 32-bit because when I upgraded to Ubuntu 12.10 it was horrifically slow and crashed after 10 minutes of use by freezing.

I would like to know, from a ubuntu command or menu, if my computer is compatible with Ubuntu 12.10 64-bit. Also, do you think that upgrading will resolve my problem or does it come from something else?

Thanks, mjchopperboy

If you are uncertain, there is no harm in trying the 64-bit version. If your machine turns out to be 32-bit only, the installer will simply fail right at the beginning while letting you know that you have the wrong version of the kernel.

  1. Try installing 64-bit version.
  2. If it fails, install 32-bit version. No harm done.

64 bit is about memory addressing. So if your computer has more than 4 gig memory you use 64bit if less you use 32 bit. There is no command that will tell you if you are compatible.

Best thing to do is use the "Live CD" and test it out. That way you can see if its compatible with your wifi and screen which are the most important aspect.
