AMD Radeon RX Vega 56
The new Radeon RX Vega 56 pumps out a respectable 29-31MH/s and stabilizing somewhere in the 30MH/s range, but what I haven't read online is that once the card gets hot (70C) then the ETH mining performance comes down dramatically. Once the card reaches 70C, it drops from a height of 31.4MH/s to 28.9MH/s... before it reaches the lows of 27.2MH/s, it is stable at 28.9MH/s at stock fan settings.
AMD ships the Radeon RX Vega 56 with its 8GB of HBM2 clocked at 800MHz, but I found I could overclock the HBM2 up to 955MHz with 24/7 mining performance at a peak of 36.9MH/s. This pushed the temperatures up to 73-74C again, so I increased the fan RPM speed to 3300RPM, and the temperatures landed back at 65-66C.
Power consumption wise, the Radeon RX Vega 56 without any tweaks sat at 300W. I decreased the power on the card with varying results, but landed on -5% power limit in Radeon Settings, which resulted in 62C maximum temperature on the GPU and 285W power consumption. 15W power savings, but an increase of 8MH/s is DAMN GOOD. This is rock solid stable 24/7.
Maximum OC with 24/7 operation on Radeon RX Vega 56:
- Temps: 62C
- Power: 300W
- Fans: 2800RPM
- ETH mining: 37.3MH/s
- HBM2: 955MHz
- Power: minus 18.5% @ 1269MHz
