Non-gaming power consumption of AMD's new RDNA II architecture is very impressive. In idle, the chip powers off almost completely, which brings down power consumption significantly. AMD also fixed the high multi-monitor power draw—it's now much better than NVIDIA's.
Media playback runs the memory chips at full speed, which consumes a lot of power—power consumption is well above any other card we've tested before. I suspect AMD will fix this with a driver update.
Gaming power consumption is extremely impressive, too. The Radeon RX 6800 XT only uses around 280 W during gaming, 60 W less than the GeForce RTX 3080. The peaks are higher, up to 325 W, and Furmark worst-case power is 316 W.
Originally this review was posted with gaming power measurements taken at 1080p, this has been revised to 1440p, to ensure proper loading of the card.
Recommended PSU: 650 W
