AMD has a 64-core Ryzen Threadripper. The only problem is if they wish to sell it for $1000, for instance. Shrinks are solutions, too.
Intel has so serious influence over the entire industry, that fixing the compilers and Microsoft's things straight away will be the single smallest problem.
For Intel, it's more difficult to get the actual hardware done right on the manufacturing lines.
You actually believe that? how many software projects have you been involved in? Furthermore how many software projects have you been involved in that have potential affected user base in the billions? There is a reason it took so long to fix the windows scheduler for Zen and that wasn't because of AMD its because changes in software stacks that have billions of users takes time and testing. Regardless they still fall over at the fabric/interconnect level. When Intel have a scalable low power draw interconnect you let me know
For what it is worth have a look at Intel Xeon Soma-B3 and you can see for yourself that intel have tried and failed to emulate ryzen, the reason they fail? Interconnect...
