I believe transformer based "VRMs" (they are actually unregulated) like these https://www.techspot.com/images2/news/bigimage/2020/05/2020-05-14-image-22.jpg https://www.techspot.com/images2/news/bigimage/2020/05/2020-... is the future as a way more practical way to deal with power supply of few hundred Amp chips. 16 phase buck controllers are greatly, greatly impractical, and the only reason the industry is stuck with them is that nobody was brave enough to do serious research into making responsive magnetic based DC-DC, while everybody knew that such thing should be possible. It's interesting curiosity how Taiwanese made it an industry trend out of multi-phase bucks because people who were making first PCs in Taiwan had rather subpar electronics engineering education, or were basically self-taught, and designed computer boards by trial end error back in nineties.
