right direction now. So, let's start. All right. Well, our first email is from Logan, who explained why the 64-bit download of a distribution is called AMD64. So, he wrote, 64-bit is listed as AMD because AMD created the current 64-bit and Intel adopted that. At least that's the logic I use for the reason. And we also got an explanation from Ken. So, I've combined two emails together here. I'm sorry, Bill. That's cheating. Well, it was a short one. Who expanded on that and said AMD didn't create the first 64-bit CPU. They existed long before that. Intel's 64-bit was a new architecture, IA64. AMD extended the x86 or IA32 architecture to 64-bit, hence AMD64. Intel followed on with their own extension to the x86 architecture called IA32e, later EM64T. AMD64 and EM64T are software compatible, but there are architectural differences. AMD64 nomenclature is a distro-specific choice. Ubuntu and their derivatives use AMD64, while CentOS and OpenSUSE use x86 underscore 64. Yeah, I've seen the (4/45)
