Both AMD and Nvidia’s next-gen flagship graphics cards could be seriously power-hungry, at least if the latest gossip from the grapevine proves to be true.

3DCenter has been on another rumor-collecting trawl, as picked up by VideoCardz, and the tapped info from multiple hardware leakers (on Twitter and elsewhere) suggests that the top dog cards from what could turn out to be the RTX 4000 and RX 7000 ranges will pull in over 400W in terms of power demands – possibly well over.
