As x86 has been around for a long time, it exists in both 32-bits and 64-bits, so just with x86 there’s no real way of saying. As said in a comment on another answer, x86 usually refers to the architecture (as opposed to SPARC for example). So although both x86 and 圆4 platforms start with an x, the x doesn't stand for the same thing, one being the CPU model number (286, 386.) and the other being the manufacturer (AMD64, Intel64). Answer (1 of 6): TL DR: It doesn’t say, could be both.

AMD originally used the AMD64 moniker for this new platform, but then Intel started making AMD64 compatible chips (as Intel 64), and it was renamed to 圆4 because it wasn't an AMD exclusivity anymore.

When AMD came out with the 64 bits extensions of the classic Intel CPU instruction set, applications and OSes needed to be recompiled to take advantage of the new features, making them incompatible with the previous Intel CPU models. Then marketing concerns took precedence over engineering and Intel started to give its CPUs non-numeric names (Pentium2, Core2) and the technical model number was buried in the tech specs. A partir de MAME v0.216, cette version 32-bit n'est plus mise jour officiellement par son auteur d'origine. Uniquement ddi au jeux d'arcade, il ne contient (volontairement) pas les jeux suivants: flipper, poker, autres jeux d'argent. So you would have the x86 version of an application, the Alpha version of an application, or the SPARC version. Il s'agit de la version pour processeurs 32-bit compatible partir de Windows XP SP3. When comparing architectures, people would use the x86 moniker to refer to the Intel main line of 16/32-bits CPUs. There also used to be competing CPU architectures from other manufacturers, incompatible with Intel, such as SPARC, MIPS, ARM, Alpha.

Applications and operating systems (DOS, Windows) able to run on one of these CPUs would most likely run on another CPU of that line, albeit slower or faster. Intel CPUs at the heart of the PC architecture used to have model numbers ending with number 86.
