x86 refers to the intel processor numbering from way back
processors were
8086
There was a 186 but not used in processor line ups for desktop PC's AFAIK
80286 (286) My first in PC in 1990
80386 (386)
80486 (486) My second PC in 1993
then the 586 became pentium and so on, the 86 suffix was not used.
x86 became used to describe software compatibility as 32 bit, 8086 was 8 bit, 80286 and 386 16 bit if I recall, the advent of PCI and the 486 gave us the first proper 32bit bus
Now X64 just describes the bit width but it is still x86 compatible.
Trust the history lesson made sense.
It made perfect sense thank you
