This question already has an answer here:

I have a newer Intel I-7 laptop, with Windows 8, 64-bit. I downloaded the Ubuntu 12.04.2, 64-bit .iso file (as recommended on the website). I'm a little concerned because the filename is "ubuntu-12.04.2-desktop-amd64.iso", which sounds like it's intended for an AMD processor. Do I have the right file for my Intel machine?

amd64 is the name for the 64 bit architecture (as in i386 for the 32 bit). You have the correct file yes. See askubuntu.com/questions/269462/… and askubuntu.com/questions/54296/… –  Rinzwind May 18 '13 at 23:12

"AMD64" is the instruction set as created for 64-bit AMD processors, but the Intel equivalent, IA32e (now called "Intel 64") is very compatible, and Linux and GCC do not contain or (by default) generate code that would work on one but not the other. The ISO you have will work with the i7 CPU.

File is correct: suffix "amd64" is intended for cpu x86_64, intel or amd; x86_64 is 64-bit extension for 32-bit generation of x86 instruction set. AMD named it AMD64, Intel initially used the names IA-32e and EM64T before finally settling on Intel 64. For cpu 64-bit Intel (itanium) the correct file is with prefix "ia64"
