x86 is a bloated, toxic instruction set architecture (or rather a family of them) used mostly in the desktop computers -- it is the most widely used architecture, used in Intel and AMD CPUs.
It is a CISC architecture and boy, complex it is. LMAO there are instructions like PCLMULQDQ, MPSADBW (multiple packed sums of absolute difference which does something like cross correlation ??? xD) and PCMPESTRI (which does like many possible string searches/comparisons on strings of different data types like subset or substring with many different options). Basically if you smash your keyboard chances are you produce a valid x86 instruction xD
