AMD RX 6800 XT Review

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.


Overall performance efficiency for the RX 6800 XT is remarkable. We can see Vega 64 sitting bottom of all three charts, and it is easy to forget that was AMD’s flagship GPU just three years ago. Today, the RX 6800 XT offers well over double the performance per Watt based on the 4K data.

The real comparison is against RTX 3080, however. The RX 6800 XT offers better performance per Watt for 1080p, 1440p and 4K gaming. The differences are small, yes – with about 5% in AMD’s favour using the 1440p data. But even so, this really does show how far AMD has come, with its RX 6800 XT able to compete with Nvidia’s self-proclaimed flagship in terms of overall performance, but also in terms of performance efficiency.
