64 bit Assembly introduction

Question

I am looking for an articles which introduce Intel 64 bit processor and Assembly: list of x64 registers, commands syntax etc. for programmers familiar with 32 bit Assembly. Kind of "What's new" for 64 bit processor.

The ["Gentle Introduction to x86-64 Assembly"](http://web.archive.org/web/20160315213751/http://www.x86-64.org/documentation/assembly.html) article on x86-64.org is exactly what you're looking for (archive.org link because it's down ATM). It uses AT&T syntax, but the concept doesn't change for Intel syntax. See also other links in the [x86 tag wiki](http://stackoverflow.com/tags/x86/info) — Peter Cordes, Aug 26 '16 at 23:27
