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).

Lastly, at 4K, the RTX 4090 is in a class of its own in terms of efficiency. Its next closest rival is the RTX 3070, but the 4090 is still over 50% more efficient, and that increases to 84% when compared to the RTX 3090 Ti. It is highly impressive how efficient the Ada architecture is, and we'd expect this to only get better on the lower-power SKUs.
