In terms of raw computing power, the top version of Fury reportedly offers over 54 percent more teraflops than the Radeon R9 290X while having a TDP that is 10W higher.
Fiji, and the Fury line of cards which are based on it, feature notable improvements across the board. Performance is obviously significantly improved. Fury X is faster than the R9 290X by a minimum of 54%. Which brings us to the second major improvement. Fury X achieves this performance improvement with a TDP that’s a meager 10W higher. Which makes Fury X 48% more power efficient than AMD’s previous single GPU flagship the R9 290X, which is quite remarkable.
