By using the GPU-Z Board Power data in conjunction with the 11-game average FPS data we presented earlier in this review, we can work out performance per Watt for each graphics card. This is presented as FPS per Watt.
Due to the increase in power, coupled with the very small (2%) performance gains, the RTX 3080 Eagle does offer very slightly worse performance per Watt than the Founders Edition. It's not much at all, but it is an interesting point nonetheless.
