I am downloading Ubuntu 16.04.2 LTS when I click on download, then it's shows "amd64" somewhere in the name of file like "ubuntu-16.04.2-desktop-amd64.iso" , What does it mean? Is this not for Intel processors?

AMD64 is the standard designation for Intel/AMD architecture 64-bit versions of the operating system. It is AMD64 because AMD produced the first-marketed 64-bit CPU chips, and the competing Intel 64-bit hardware never really took off (Intel wound up copying the AMD instruction set, in the end, as I understand it).

It simply means that you're downloading the 64 bit version of the Ubuntu installer.
amd64 is just the general name of the standard 64 bit architecture used in most modern desktop and laptop devices. This is not specific to CPUs manufactured by AMD but works for all brands.
Note that the 64 bit installer will only run on CPUs that support this 64 bit architecture. Older processors might only support 32 bit, in that case you would not be able to start this installer on those.
