Disappointing. AMD has finally made itself truly relevant again and one of the key movers behind that jumps ship to the opposing team. He might as well call himself Kevin Durant.
I don't think it's necessarily him "jumping ship" so much as it is him not being constantly needed. If he's designing a new CPU architecture, he doesn't necessarily need to stick around after that core design has been finalized. He worked at AMD for a couple years in the late 90s, then left to worked at other companies including Apple, then came back to AMD for a few years to work on Ryzen, then went to Tesla for a couple years, and is now at Intel. He left AMD in 2015, well over a year before the Ryzen processors he worked on were released.
