Cards are Radeon VII, those makes around 88-90MH when stock and more than 95-96MH with OC, could be pushed around 100MH, but I think safe and stable are at 1100MHz Mem and 1900MHz GPU, for 95 to 97MH for 260-290Watts consumption.

More efficient are Radeon 5700XT with under 100Watts consumption for around 51MH, but more cards needed.
