TOP-FLIGHT GRAPHICS cards are notoriously power-hungry. The next generation of Nvidia RTX 4000 cards will continue this trend, and rumor has it that the AD102 GPU will debut with 450W and 600W versions, but talk of an 850W version is wild (think of the cooling that would need). AMD’s next generation of cards, due later this year, is based on RDNA 3 silicon. Power requirements are expected to be less dramatic, but at 450-480W, not exactly parsimonious either.
