Using the graphics card-only power draw figures presented earlier in the review, here we present performance per Watt on a per-game basis for all twelve games we tested at 2160p (4K).

12-Game Average at 2160p (4K):
At 4K, performance per Watt numbers converge, and there aren't huge differences between any of the GPUs tested. That said, RX 6800 does prove the most efficient GPU, while the RTX 3080 Ti and RTX 3090 are both on level pegging.
