Indeed - processors don't loop, they just jmp

Right in general, wrong in detail. The x86 family has the rep, repz and repnz prefixes since at least 1978 that each implement an implicit while loop in combination with "string" instructions cmps, ins, lods, movs, outs, scas, stos, without any jumps in assembly code.
