There's a good reason that there isn't any real competition. Hardware design is extremely difficult, and extremely labor intensive. amd64 has an overwhelming number of op-codes, and competitively implementing all of them is a multi-billion dollar project. If you want to compete with Intel or AMD in the CPU market, you are talking tens of billions in NRE before you ever have something that is remotely competitive. And then you have to do it all over when we switch from 14nm to 7nm, and then again when we go from 7nm to 3nm. If you want more competition, you have to level the playing field by banning most of the op-codes. But even then you still have crazy amounts of pipelining and other optimizations which are nontrivial to figure out and very expensive to implement. Intel is in a great position.
