For better or worse AMD has always been much more willing to quickly throw everything out to go with a completely new design paradigm. Something it was a massive bust like X2 or Bulldozer. Sometimes it's the Athlon or the Zen.

The only time Intel really did that was with the end of the P4 and frankly even then they waited as long as they could before doing it. The rest of the time it's all carefully planned stepped increase and safe design change.

Both have their advantages, but for your question it means Intel will have to take a leap they clearly don't like taking.

Historically most successful AMD designs came from the outside. 286 was Intel clone, Am386 Intel microcode copy. Am486 lagged by one year, offered lower performance and was still developed using Intel IP. K5 first 100% AMD design, slow and late, competed in the bottom low end, considered a failure. K6 100% external design by NexGen, let AMD move up to middle of the market. K7 designed by DEC Alpha team and manufactured in Motorola partnership, great success.
