FUD Zilla says there's been no confirmation or assurance that Raja is indeed coming back later this year, the site claims it looks like that decision has yet to be made. The Vega architecture did not result in the hoped success, but AMD still sold every single piece it made thanks to hungry demand from the cryptocurrency market.
Honestly it is hard to imagine who could take over from Raja running the RTG, the graphics part of AMD. It might as well be someone from the outside but as we said above, right now, the teams are working as if Raja is returning in a few months.In the end, it looks like the result of this ordeal is that the Radeon Technologies Group lost some of its autonomy. Vega wasn't what it was hyped up to be, and we expect AMD will soon start hyping up its Navi architecture.
All RTG marketing now reports to the worldwide marketing lead. The guy who use to be a VP of the worldwide market, John Taylor, is now a chief marketing officer. He worked alongside Lisa and helped to make Ryzen and Epyc into very successful and desirable products.
