I am using Ubuntu 14.04 32-bit LTS for a while and I'd love to try Ubuntu 16.04 64-bit LTS. In Ubuntu download page I found 64-bit ISO image as ubuntu-16.04-desktop-amd64.iso, I am bit confused because it mentioned amd64.
Can this image ubuntu-16.04-desktop-amd64.iso can be run on intel 64-bit processors?
amd64 is the one you want. It works for both Intel and AMD x86-64 processors.
The reason it's named amd64 is because Intel created a 64-bit processor line called Itanium that wasn't based on x86, and it didn't do very well. AMD decided instead to base their 64-bit chips on x86, so the name amd64 was initially used in certain areas like Linux processor type names, and it stuck.
amd64 is the x86 instruction set, so it's Intel as well as AMD. It's also sometimes called x86-64 or x64.
So yes, amd64.iso can run on Intel 64-bit processors, just as i386 works on 32-bit ones.
