I currently have a netbook with Intel Atom N550 CPU. For the longest time I had been using 32-bit OS's on this PC, until I recently found out that apparently this CPU supports 64-bit. Checking at Intel's site about this CPU's Spec, it supports Intel® 64, and with the help of few checker I confirmed it does supports it. But I have seen that some sites says AMD64 is not same as Intel64 and the latest Ubuntu LTS 18.04 only has AMD64 iso. So can I install that AMD64 on Intel64?
Thanks!
According to the official Intel Atom Processor N550 (1M Cache, 1.50 GHz Product Specifications- Intel ARK webpage, the Intel Atom N550 has a 64-bit instruction set, so the Ubuntu 18.04 amd64 .iso file is compatible with this processor. Ubuntu 18.04 does not have a 32-bit .iso file, so the Ubuntu 18.04 amd64 .iso file is the correct .iso file to install.
In general i386 in a file name means that it is is compatible with Intel 32-bit processors and amd64 is compatible with both Intel 64-bit processors and AMD 64-bit processors. As far as 32-bit vs. 64-bit operating systems are concerned i386 packages are compatible with 32-bit operating systems and amd64 packages are compatible with 64-bit operating systems.
