Radeon VII can be more power efficient than 2080 actually if you undervolt it a bit and without losing any performance at stock. The German guys did it in their review. There are a few things I really don't like about this card though. broken drivers ridiculously loud cooler a bad contact between a hot spot and the cooling system that can be actually fixed manually which leads to -10C reduction in temperature. Does AMD hire monkeys instead of engineers?? PS About OCing..the card CAN OC and pretty good.. the problem is the driver is buggy as hell. 3dnews managed to push it to 2k without using dry ice, but they had to max its terrible fans 1) 1,13V, +20% power, maxed out fans, 2002 Mhz core clock but they decided to test it with these settings instead 2) 1,08V, 1914/1950Mhz under load.
