    there's no 8-bit x86. although it's possible to emulate other 8-bit architectures Commented Jun 11, 2016 at 16:49

    This question does not make much sense without more clarifications. Why are you mentioning QEMU? Are you asking about whether the x86 can operate as an 8 bit processor or whether QEMU does emulate such (hypothetical) 8 bit mode of the x86 properly? Commented Jul 3, 2016 at 4:54

    @hippietrail 8086 is not an 8-bit architecture. 8088 is just 8086 with a smaller external bus Commented Apr 27, 2020 at 8:20

    @hippietrail no, 4004 and 8008 are 4 and 8-bit CPUs. 8086 and 8088 are 16-bit ones. 80-bit is the width of an x87 register and has no relation to integer registers in x86 whatsoever Commented Apr 27, 2020 at 9:30
