Why is x86 not x32

Yea, I left out the because I honestly couldn't remember if it had been a released product and was feeling too lazy to look it up This answer has nothing wrong, but I honestly think Daniel's should be the accepted one, as it's much more detailed. Show 1 more comment. Later, because people are lazy, the x became known simply as the x So, in answer to your question, because x64 is shorter than x Daniel C. Sobral Daniel C.

Not to nit pick but to be compltely exact, AMD never marketed a 64 bit chip. Additionally, I believe Intel faced trademark issues because they were just using numbers and you can't trademark a sequence of numbers, that is why what would have been the became the Pentium, a made-up name that they could continue to trademark. The chip has bit instruction set and bit registers, that makes it bit chip.

I don't know where you get the impression that AMD never marketed a bit chip from. It's true though, that AMD never marketed a bit that breaks compatibility with bit chip, like Intel did with its IA And calls bit x86 i It's only or at least mostly in the Windows world that x86 specifically means bit x Most hardware people talking about CPUs understand x86 to mean any CPU that's backwards-compat with , regardless of what mode its operating in normally bit long mode, or sometimes bit compat mode under a bit kernel.

Add a comment. Joel Coel Joel Coel Overmind: x64 and IA were always separate things. IA is completely unrelated to x86 or x Except that early IA implementations included an x86 core for compat reasons, because Intel Yes, that is correct.

IA short for "Intel Architecture, bit", sometimes also called i is the bit version of the x86 instruction set architecture, designed by Intel and first implemented in the microprocessor in Definition of: x Also called "x," modern xbased laptop and desktop computers have bit CPUs rather than 32 bits.

The x64 generally refers to the hardware, not the operating system. Difference between x64 and x It usually refers to x86 for 32 bit OS and x64 for system with 64 bit. Lucia Cerchie - Nov 9.
