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):

Up at 4K, this is where the 7900 XTX is at its most efficient. We can see a generational improvement in performance per Watt of 29% versus the RX 6900 XT, and 35% versus the 6950 XT. Ada Lovelace is the more efficient architecture however – based on the GPUs released so far, at least – as the the 7900 XTX delivers 11% and 14% worse efficiency versus the RTX 4090 and 4080, respectively.
