85 Mhs 0 core / 0 mem TDP - 100% 320 Watt
91.5 Mhs 0 core / 500 mem TDP - 75% 240 Watt
96.3 Mhs 0 core / 950 mem TDP - 75% 240 Watt
95.4 Mhs 0 core / 950 mem TDP - 70% 225 Watt
96.5 Mhs 50 core / 950 mem TDP - 75% 240 Watt
96.5 Mhs 100 core / 950 mem TDP - 75% 240 Watt
Two 5700xt hashes 108Mhs with 230w to 250w power consumption
Three 5600xt hashes 114Mhs with 255 to 270w power consumption
There's no big difference in terms of efficiency, at least in my opinion
Maybe the new navi cards will increase this efficiency
Most Nvidia cards I used to reduce TDP to 60% without any decrease in hash, but this 3080 looks very hungry power
In my country it's almost impossible to get one, there's no cards to buy, even the 3090 are out of stock
