x86 traces it's DNA all the way back to the 8008 which led to the extended 8080 which led to the backward compatible 8085 then 8086 and the x86 architecture. 8008 was almost a full decade before the launch of the iAPX 432. The roots of x86 were in one of the first major ISAs ever created (and something like the 2nd or 3rd microprocessor architecture) which is pretty remarkable when you think about it.
