All current Intel/AMD processors (since Intel Core/AMD K6) are RISC cores with a complex instruction decoder in front of them. There's more to a processor core than the instruction set, and both pipelining and out-of-order execution have nothing to do with the instruction set architecture. There have been in-order x86 processors (Transmeta and Via, Intel before the Pentium Pro), and there are plenty out-of-order RISC processors: POWER4 and up, SPARC T4, RISC-V, many ARM Cortex models.
