Pretty much every high-power high-efficiency core (whether x86 or arm or PowerPC or whatever) breaks instructions up into an extremely reduced instruction and executes those. There was a point where Pentium processors were effectively just executing RISC. There's a great write-up about it here: https://fanael.github.io/is-x86-risc-internally.html https://fanael.github.io/is-x86-risc-internally.html
