Non-gaming power consumption matches the RX 6800 XT exactly, which isn't surprising because the only difference between both cards is one additional power phase for vGPU, and more CUs, which aren't active in non-gaming states. With this generation, AMD made big improvements in multi-monitor power consumption; it now beats NVIDIA. Media playback, on the other hand, consumes a lot of power because the memory is clocked at full speed.
Gaming power draw is an interesting one. Furmark and gaming maximum power are identical to the RX 6800 XT, but the average gaming power is 10 W higher. Both cards are rated for the same TDP, and people wondered how AMD could achieve additional performance in this scenario: Seems the additional CUs are able to take over fine-grained workloads in situations where the GPU isn't running at its power limit.
Recommended PSU: 850 W
