it hard to find a gigabyte rx 5700 that did do less than 140w from the wall. if you want rx 5700 xt with good power consumption get a Sapphire nitro+ or a pulse.
i have a nitro +SE that is doing 58.3mh with 100w from the wall(74w In software)

Is this your sapphire setting?
1331/1860
vcore=756mv
mvddc=775
mvddc if I'm not wrong is the voltage of memory controller, why you reduce this? any effect on mem temp and power?
To get 58.x MH i need to mod bios, push mem to 1900, and the power at wall hit 158W. How can you manage to get that high speed with only 1331/1860
