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):
Efficiency at 4K is not quite as good as it was at 1440p however, as the RTX 4080 does fall away in terms of performance relative to the 4090. Still, it does just about manage an improvement in overall efficiency, but only by 3%, so there's no much in it.
