Well AMD has gone wider - to 5 or 6 wide depending on how you count it in Ryzen. Intel hasn't really been able to make any changes to make any major uarch changes in years, since they've been stuck on Skylake (and all the various Skylake++ variants that followed which were Skylake in name only). In Skylake, most of the effort seemed focused on bringing AVX-512 to bear, and outside of that the basic design is largely the same as Haswell. Here's hoping that Apple's chips portend an increase in width in mainstream x86 chips as well.
