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 1080p.

12-Game Average at 1080p:
Such large increases in power draw, despite fairly insignificant performance improvements, means that performance per Watt efficiency of all three models is well below that of the original RX 6000 series cards. The RX 6650 XT, for instance, is about 10% less efficient than the vanilla RX 6600 XT.
