> You can reuse a successful core design like the Pentium 4 and adapt it to a modern 14nm or 10nm process
The Pentium 4 is not a technical success. It was an inflexible hot rod with a compromised architecture driven by marketing. That is why its architecture was abandoned.
The 486 started out on a 1000nm process. Shrinking it to a modern process and enhancing it with modern goodies like a larger cache is comparatively easy.
