I would argue that AMD is not the reason they are more power efficient, it's TSMC.
Intel bet on a fabrication process that did not succeed. I will bet in the next 2 years Intel will be on par with AMD again.

Why ?
For example, the chiplet approach that AMD embraced allowed AMD to put together far more powerful CPUs, i.e. with more cores and at a competitive price, than Intel could.
