x86 is a [bloated](bloat.md), toxic [instruction set architecture](isa.md) (or rather a family of them) used mostly in the [desktop](desktop.md) computers -- it is the most widely used architecture, used in [Intel](intel.md) and [AMD](amd.md) [CPU](cpu.md)s.
It is a [CISC](cisc.md) 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
