Sorry, not going to happen. Why would Intel add more competitors into a market where it has a duopoly?
- The server and desktop markets move to ARM. The AArch64 instruction set becomes the default that people develop and deploy on. Optimizing for x86_64 CPUs becomes an afterthought. Intel only sells CPUs to organizations that have legacy systems somewhere that cannot be emulated. Intel has to enter the highly commoditized ARM market to stay competitive.
- The server and desktop markets largely stay on x86_64 as a result of Intel licensing x86_64 to three other vendors, increasing competition. The market is not commoditized, because Intel can decide who they license x86_86 to and also control extension to the instruction set. They lose market share due to the increased competition. But they can compete on their own architecture that they control.
Of course, these are extremes. But given that the current fastest supercomputer uses ARM and Apple showed that ARM is fit for the desktop, I am pretty sure that Intel is (or should be) worried about the first scenario.
In any event it's too late. They maybe had an chance of fending off Arm a few years ago - by the time any licensing now kicks in Arm will have established itself in the server / PC market.
So the only sensible strategy for Intel is to make the most of x86 whilst they can.
