Nothing wrong with Vega itself but it's really a year late. Then the power consumption is a step back. It performs the same as a GTX 1080 but it consumes more power. 245 - 345 watts vs 180 watts.

The other thing is clock for clock it performs the same as the R9 Fury X which is old meaning they haven't improved their IPC.
