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 1440p.
Per-Game Results at 1440p:

12-Game Average at 1440p:
At 1440p, the 4070 remains a highly efficient GPU, now just about edging ahead of the RTX 4070 Ti. It's still 67% more efficient than the RTX 3080, while offering a 17% improvement in performance per Watt versus the RX 7900 XT.
Ray tracing results
As a bonus, we now include the power figures for all six games we test with ray tracing enabled.
6-Game ray tracing average:
For ray tracing, the 4070 is still looking at a 60% uplift versus the RTX 3080. The increase in efficiency over the 7900 XT is lower than it was at 1080p, but is still a healthy 33% in favour of the 4070.
