Sep 05, 2017 · Straight away it is clear that AMD Radeon RX Vega 64 consumes more power than AMD Radeon R9 Fury X. Though, Fury X can reach some high wattages as well, up to 400w. AMD Radeon RX Vega 64 on averages pulls well over 400w all the time though, in every game, where Fury X hits below 400w in many games. Given the fact that AMD Radeon RX Vega 64 is providing 30-40% higher performance, it logically makes sense.
