By using our GPU-only power data in conjunction with the 14-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.

Well well well. RDNA 2 completes a truly astonishing turnaround for AMD. From the sheer inefficiency of Vega 64, the GPU which was AMD's flagship just three years ago, we are now in a situation where the RX 6800 is tied with the RTX 3070 for the most power efficient GPU on the market.

That's right – at 1080p, 1440p and 4K, the RX 6800 offers identical performance per Watt when compared to the RTX 3070, while at 1440p it delivers 18% higher performance per Watt when compared to the RTX 3080. This really is quite remarkable, again considering how far behind AMD was just three years ago, and also when considering it's the same 7nm process as the RX 5700 XT.
